Anemia is a nutritional disorder that affects mostly children below 2 years and is mainly contributed by iron deficiency. Moringa oleifera leaves are rich in iron and other essential nutrients necessary for iron metabolism. We investigated the effect of M. oleifera leaf powder supplementation on reducing anemia among children below 2 years. A community‐based interventional study was conducted that enrolled 95 anemic children who were followed for 6 months. The intervention communities received M. oleifera leaf powder and nutrition education, while control communities only received nutrition education. Changes on mean hemoglobin (Hb) concentration and anemia prevalence were compared between the two groups using t test and proportional test where appropriate. At baseline, the mean Hb concentrations of control and intervention groups were 7.9 g/dl (SD = 1.3) and 8.3 g/dl (SD = 1.6) g/L, respectively (p‐value = 0.0943). After 6 months, anemia prevalence significantly decreased in the intervention group by 53.6% (100%–46.4%; p

Introduction:childhood undernutrition is one of the leading causes of morbidity and mortality in children below five years of age especially in developing countries like Tanzania, particularly in rural area. Inappropriate child caring and feeding practices have been strongly associated with it. Many actions have been taken to reduce prevalence of undernutrition in children in Ngorongoro district, however, the problem persist. This study identified risk factors associated with undernutrition in children under-five years of age in Ngorongoro district, Arusha region. Methods:a health facility-based unmatched case-control study was conducted with 400 (100 cases and 300 controls) children aged 6-59 months. Cases included children with undernutrition according to the WHO anthropometric indicators. Controls were children within the normal range of these indicators. Both cases and controls, were obtained from children attending the Reproductive and Child Health (RCH) for assement of growth and development or admitted in pediatric ward. A questionnaire was used to collect demographic characteristics, child health and caring practices and environmental factors. Height, weight and Mid Upper Arm Circumference (MUAC) were measured using standard approaches. We employed logistic regression analysis to identify significant risk factors for undernutrition. Results:undernutrition was associated with young age of mothers/caregivers (adjusted Odds Ratio (aOR)=38.8, 95% CI: 15.38-59.03.); early age of initiation complementary foods (aOR=13.6, 95%CI: 3.15-59.06); a child having diarrhoea in past one month (aOR=4.0; 95%CI: 1.76-12.85); large family size (aOR=6.1, 95% CI: 2.16-16.90); low frequency of feeding (aOR=3.9, 95%CI: 1.59-9.58); low birth weight (aOR:=7.3, 95%: CI: 1.15-46.70); and source of drinking water; well (aOR=16.3, 95%: CI: 1.81-147.05) and surface water (aOR=16.18, 95%CI: 1.85-141.71). Conclusion:household and individual characteristics of the children and mother/caregiver are important predictors of undernutrition in this community. Tailored interventions, instead of blanket approaches, should be designed to mitigate and eliminate childhood undernutrition in Ngorongoro.

Background Precise detection of Plasmodium infections in community surveys is essential for effective malaria control. Microscopy and rapid diagnostic tests (RDTs) are the major techniques used to identify malaria infections in the field-based surveys. Although microscopy is still considered as the gold standard, RDTs are increasingly becoming versatile due to their rapid and adequate performance characteristics. Methods A malaria prevalence cross-sectional survey was carried out in north-western Tanzania in 2016, aimed at appraising the performance of high sensitivity Plasmodium falciparum (HSPf) tests compared to SD Bioline Pf and microscopy in detecting P. falciparum infections. A total of 397 individuals aged five years and above were tested for P. falciparum infections. The sensitivity, specificity, positive, and negative predictive values (PPV and NPV) of microscopy, Pf RDT and HSPf RDT was determined using PCR as the gold standard method. Results The prevalence of P. falciparum infections determined by microscopy, SD Bioline Pf, HSPf and PCR was 21.9, 27.7, 33.3 and 43.2%, respectively. The new HSPf RDT had significantly higher sensitivity (98.2%) and specificity (91.6%) compared to the routinely used SD Bioline Pf RDT(P Conclusions HSPf RDT had better performance when compared to both microscopy and the currently used malaria RDTs. The false negativity could be associated with the low parasite density of the samples. False positivity may be related to the limitations of the expertise of microscopists or persistent antigenicity from previous infections in the case of RDTs. Nevertheless, HS PfRDT performed better compared to routinely used Pf RDT, and microscopy in detecting malaria infections. Therefore, HS Pf RDT presents the best alternative to the existing commercial/regularly available RDTs due to its sensitivity and specificity, and reliability in diagnosing malaria infections.

ObjectiveThis study compares two methods for clinical diagnosis of childhood pneumonia that aim to estimate rates of underdiagnosis and overdiagnosis of childhood pneumonia by examining the sensitivity of Integrated Management of Childhood Diseases implementation in routine care against lung ultrasound (LUS) diagnosis.SettingWe conducted observations in 83 public health facilities (dispensaries, health centres and district hospitals) in Pwani, Dodoma and Tabora, Tanzania between October and December 2017.MethodsWe used a novel method to estimate rates of underdiagnosis and overdiagnosis of childhood pneumonia by comparing directly observed public provider diagnoses to the results of diagnoses made by trained clinicians using Mindray DP-10 ultrasound machines. We perform multivariate analysis to identify confounding effects and robustness checks to bound the result. We also explore a number of observable characteristics correlated with higher rates of agreement between provider diagnoses and ultrasound diagnoses.ResultsWe observed 93 providers conducting exams on patients aged 2 months–5 years who presented respiratory symptoms or were given a respiratory diagnosis by the provider. Of these 957 patients, 110 were excluded from analysis resulting in a final sample of 847.17.6% of cases identified as pneumonia via LUS examinations in our sample were diagnosed as pneumonia by providers, suggesting that a significant number of pneumonia cases for which care is sought in the public sector go undiagnosed. Provider knowledge of breath counting and years of experience are positively correlated with higher agreement. While clinical examination rates are not statistically correlated with agreement, it is notable that providers conducted a clinical examination on only about one-third of patients in the sample.ConclusionOur results suggest that provider training and knowledge of clinical examination protocols for pneumonia diagnosis are predictive of correct diagnosis of pneumonia and should be further explored in future research as a tool for improving quality of care.

Background The Lake and Western Zones of Tanzania that encompass eight regions namely; Kagera, Geita, Simiyu, Shinyanga, Mwanza, Mara Tabora and Kigoma have consistently been reported with the poorest Maternal Newborn and Child Health (MNCH) indicators in the country. This study sought to establish the provision of Emergency Obstetric Care (EmOC) signal functions and reasons for the failure to do so among health centers and hospitals in the two zones. Methods All the 261 public and private hospitals and health centers providing Obstetric Care services in Lake and Western Zones were surveyed in 2014. Data were collected using questionnaires adapted from the Averting Maternal Deaths and Disabilities (AMDD) tool to assess EmOC indicators. Managers in all facilities were interviewed and services, medicines and equipment were observed. Spatial Mapping was done using a calibrated Global Positioning System (GPS) Essential Software for Android and coordinates represented on digitalized map with Arc Geographical Information System (GIS) software. Population data were according to the 2012 Housing and Population National Census. Results In total 261 health facilities were identified as providers of Obstetric care services, including 69 hospitals and 192 health centres which constitute an overall facility density of 8 per 500,000 population. The three most common EmOC signal functions available in the 3 months preceding the survey were oxytocics (95.7%), injectable antibiotics (88.9%) and basic newborn resuscitation (83.4%). The lowest proportions of facilities performed Cesarean section (25.7%) and blood transfusion (34.6%). Policy restrictions were the most frequent reasons given in relation to nonperformance of blood transfusion and Cesarean section when needed. Lack of training and supplies were the most common reasons for non availability of assisted vaginal delivery and uterine evacuation. Overall the Direct Case fatality Rate for direct obstetric causes was 3%. The referral system highly depended on hired or shared ambulance. Conclusion The provision of EmOC signal functions in Lake and Western zones of Tanzania is inconsistent, being mainly compromised by policy restrictions, lack of supplies and professional development, and by operating under lowly developed referral services.

Background Folic acid fortification of staple foods has been in place in many countries for over two decades. Studies have shown that folic acid fortification can significantly reduce incidence of neural tube defects. Tanzania adopted a mandatory fortification policy for commercially-produced wheat and maize flour in 2011. We determined factors influencing intake of folic acid-fortified flour among women of reproductive age (WRA). Methods We conducted a cross-sectional study among WRA during March–April 2017 in Ifakara Town Council, Morogoro region. Multistage cluster sampling was used to select study participants. We used a questionnaire to capture information on demographics, awareness of folic acid, awareness of existence of folic acid fortified flour in community and intake of folic acid fortified flour. Intake was defined as reported consumption of folic acid fortified flour products at least once within 7 days before interview. Univariate, bivariate, and multivariable logistic analyses were done to evaluate factors associated with intake of folic acid fortified flour. Results The median age of the 698 participating WRA was 30 years (range: 18–49). Awareness of folic acid and folic acid fortified flour was 6.9% (95% CI: 5.2–9.0%) and 7.5% (95% CI: 5.7–9.6%), respectively. Consumption of folic acid fortified flour was 63.3% (95% CI: 59.7–66.8%). Independent factors associated with intake included being employed (aOR = 1.91; 95% CI: 1.19–3.06), having no children (nulliparity) (aOR = 2.59; 95% CI: 1.36–4.95) or having 1–4 children (aOR = 1.98; 95% CI: 1.17–3.33) (vs. 5 or more children), and folic acid awareness (aOR = 2.53; 95% CI: 1.30–4.92). Conclusion Folic acid fortified flour was used by most respondents in our study despite low awareness of existence of folic acid fortified flour in the community. Being employed, having fewer than five children, and folic acid awareness were independent factors associated with intake. We recommend scaling up of mandatory flour fortification program and doing further studies on blood folate level among women of reproductive age in Ifakara to assess fortification program effectiveness.

Introduction in 2014, Tanzania introduced the combined measles-rubella vaccine in the routine immunization schedule. Two doses of measles-rubella vaccine (MR1 and MR2) are recommended at 9 and 18 months, respectively. In 2015, MR2 coverage among eligible 18-month-old children in Tanzania was only 57%, lower than the WHO-recommended coverage (95%). During the same period Mtwara District Council (MDC) reported a coverage of 52% which is lower than the nation average. We determined factors associated with non-uptake of MR2 among children in MDC Tanzania. Methods we conducted a community-based cross-sectional survey using cluster sampling during January - April 2017 in MDC. Caretakers of children born during January 2014 - January 2015 and residing in MDC for the past three years were recruited. We interviewed participants and reviewed vaccination cards. Logistic regression modeling was employed to identify independent factors associated with uptake of MR2. Results of 1,000 children assessed, 558 (55.8%) were unvaccinated with MR2. Factors independently associated with non-uptake of MR2 included the caretaker being unaware of the ages for MR1 and MR2 administration [aOR=3.50; 95%CI 1.98-6.21; p

Background A nationwide, school, malaria survey was implemented to assess the risk factors of malaria prevalence and bed net use among primary school children in mainland Tanzania. This allowed the mapping of malaria prevalence at council level and assessment of malaria risk factors among school children. Methods A cross-sectional, school, malaria parasitaemia survey was conducted in 25 regions, 166 councils and 357 schools in three phases: (1) August to September 2014; (2) May 2015; and, (3) October 2015. Children were tested for malaria parasites using rapid diagnostic tests and were interviewed about household information, parents’ education, bed net indicators as well as recent history of fever. Multilevel mixed effects logistic regression models were fitted to estimate odds ratios of risk factors for malaria infection and for bed net use while adjusting for school effect. Results In total, 49,113 children were interviewed and tested for malaria infection. The overall prevalence of malaria was 21.6%, ranging from

Sickle cell disease (SCD) is common across Sub-Saharan Africa. However, the investigation of SCD in this area has been significantly limited mainly due to the lack of research facilities and skilled personnel. Here, we present optical measurements of individual red blood cells from healthy individuals and individuals with SCD and sickle cell trait in Tanzania using the quantitative phase imaging technique. By employing a quantitative phase imaging unit, an existing microscope in a clinic is transformed into a powerful quantitative phase microscope providing measurements on the morphological, biochemical, and biomechanical properties of individual cells. The present approach will open up new opportunities for cost-effective investigation and diagnosis of several diseases in low resource environments.

Objective To assess the validity of health facility (HF)-based data on bednet and insecticide-treated bednet possession and use by children

Use of insecticide-treated bednets (ITNs) to prevent malaria remains low, and effective distribution strategies are needed. An integrated child health campaign with free distribution of 162,254 untreated bednets bundled with insecticide, measles vaccination, vitamin A, and mebendazole for children < 5 years old ("under-5s") was conducted in Lindi Region, Tanzania. We conducted a representative household survey 3 months after the campaign. Altogether, 574 households with 354 under-5s were visited. In households with an under-5, possession of bednets and ITNs increased from 60.9% to 90.7% (P < 0.001) and from 16.5% to 37.3% (P < 0.001), respectively. Increases occurred in all wealth quintiles and equity improved. Reported bednet and ITN use the previous night among under-5s was 46.3% and 21.5%, respectively. Integrated campaigns rapidly and equitably increase bednet possession and use meriting continued large-scale implementation. However, our study found that bednets were rarely treated; thus, future campaigns should provide factory-treated long-lasting ITNs. Low ITN use underscores the need for further efforts to increase use after campaigns.

Background Community participation (CP) is a key concept under ‘primary health care’ programmes and ‘Health Sector Reform’ (HSR) in many countries. However, international literature with current empirical evidence on CP in health priority setting and HSR in Tanzania is scanty. Objectives To explore and describe community views on HSR and their participation in setting health priorities. Methods A multistage sampling of wards and villages was done, involving group discussions with members of households, Village Development Committees (VDCs) and Ward Development Committees (WDCs). Results Respondents at village and ward levels in both districts related HSR with a cost sharing system at public health facilities. Views on the advantages or disadvantages of HSR were mixed, most of the residents pointing out that user charges burden the poor, there is a shortage of drugs at peripheral health facilities, the performance of government health service staff and village health workers does not satisfy community needs, health insurance is promoted more than people actually benefit, VDC and WDC poorly function as compared to local communityparticipatory priority-setting structures. Conclusion HSR may not meet the desired health needs unless more efforts are made to enhance the performance of the existing HSR structures and community knowledge and enhance trust and participation in the health sector programmes at all levels.

Background Condoms are scientifically recommended as potential products for preventing infections attributable to human immuno-deficiency viruses (HIV). However, evidence on factors leading to their inadequate use in developing countries is still scanty. This paper reports an exploratory study of factors constraining condoms use in Tanzania from the perspectives of barmaids, guest-house workers and retailers. Methods Data were collected in two districts—Mpwapwa in Dodoma Region and Mbeya Rural in Mbeya Region—between October and December 2011, using structured interviews with 238 individuals including barmaids, guesthouse workers and 145 retailers. Data analysis was performed using STATA 11 software. Results Awareness about condoms was high among all study groups. Male condoms were more popular and available than female ones. A considerable proportion of the barmaids and guesthouses were disappointed with condoms being promoted and distributed to young children and disliked condom use during sexual intercourse. Accessibility of condoms was reported as being lowered by condom prices, shortage of information concerning their availability; short supply of condoms; some people shying away to be watched by children or adult people while purchasing condoms; retailers’ using bad languages to condom customers; occasionally condom shops/kiosks found closed when they are urgently needed; and prevailing social perception of condoms to have low/no protective efficacy. Regression analysis of data from barmaids and guesthouse-workers indicated variations in the degree of condom acceptability and methods used to promote condoms among respondents with different demographic characteristics. Conclusion A combination of psychosocial and economic factors was found contributing to lower the demand for and actual use of condoms in study communities. Concerted measures for promoting condom use need to address the demand challenges and making operational research an integral element of monitoring and evaluation of the launched interventions, hence widening the evidence for informed policy decisions.

Background: In Tanzania HIV Testing and Counselling (HTC) is being implemented through voluntary counselling and testing (VCT), provider initiated counselling and testing (PITC) and work place counselling and testing (HTC). Within these programmes, HIV status disclosure is emphasized. However, among persons who test HIV positive, many do not disclose their status to their partners and social networks. However, data are lacking on the effectiveness of the different HTC strategies on HIV positive status disclosure. Objective: To investigate which of the three HIV Testing and Counselling (HTC) strategies: Voluntary Counselling and Testing (VCT), Provider Initiated Counselling and Testing (PITC) and work place Counselling and testing is associated with improved HIV-positive status disclosure in Eastern Tanzania. Methods: Structured interviews were conducted with 455 newly diagnosed HIV-positive clients at 6 HTC sites during enrolment and at three months follow-up to collect data on disclosure status. Results: We found that PITC strategy attended a relatively higher proportion of clients 182/455(40.1%) as compared to VCT 169/455 (37.1%) and work place HTC strategies 104/455(22.9%) respectively. Among clients, about one third 130/455(28.6%) were found to be HIV-positive. HIV status disclosure rates were variable and were in order of preference of disclosing to family members 86/130(66.2 %), followed by relatives 74/130(56.9%) and sexual partners 71/130(54.6%). A high proportion of participants 77/130(59.2%) experienced violence acts from sexual partners in form of stigma and discrimination, abuse, divorce and termination from employment. In the multivariate logistic regression, disclosure to sexual partners was associated with violence acts of about two times higher (Disclosure to Partners OR=1.89) when compared to the group that did not disclose to their partners. Conclusion: PITC strategy was found to result into higher rates of HIV positive status disclosure when compared to VCT and work place HTC strategies. Stigma, discrimination and violence acts are still prevalent in Tanzania and discourages HIV positive status disclosure. Based on these findings, there is an urgent need of promoting public education on HIV transmission, prevention and treatment and enhancing strategies to reduce risky sexual behaviour and increase condom use.

In May 2003, we studied amodiaquine (AQ) efficacy in children < 5 years of age with uncomplicated falciparum malaria in Magoda and Mpapayu (with insecticide treated nets [ITNs]) and Mgome (without ITNs) in Muheza, Tanzania. The trial involved 28 days of follow-up, and data were adjusted by polymerase chain reaction (PCR) genotyping of msp1 and msp2 genes. Additionally, Pfcrt codon 72-76 polymorphisms were studied by PCR and sequence-specific oligonucleotide probe (SSOP) ELISA. In 54 cases with complete follow-up, a significant difference in late treatment failure (LTF) rates was seen (60.7% in ITN versus 88.5% in non-ITN villages, P = 0.02) before PCR correction. However, after PCR correction, 23 cases (60.5%) were confirmed as reinfections, giving a true LTF rate of 21.4% (6/28) and 34.6% (9/26) in the above settings, respectively. Frequency of Pfcrt CVIET haplotype mutation pretreatment was high (97.0%); the remaining samples were CVMNK. We conclude that AQ alone is no longer effective in the study area.

Background In Tanzania and elsewhere, medicinal plants, including Maytenus senegalensis, are still widely used in the treatment of malaria and other ailments. The aim of the present study was to investigate the in vivo antiplasmodial and toxic effects in mice. Methods Oral antiplasmodial and acute toxicity of the ethanolic root extract of M. senegalensis was evaluated in mice. The Peters 4-day in vivo antiplasmodial effect against early rodent malaria infection in chloroquine-sensitive Plasmodium berghei NK 65 strain in mice. Results The M. senegalensis extract was found non-toxic and the oral median lethal dose in mice was determined to be greater than 1,600 mg/kg body weight. The findings revealed a significant (P = 0.001) daily increase in the level of parasitaemia in the parasitized untreated groups and a significant (P 100 mg/kg > 75 mg/kg > 50 mg/kg > 25 mg/kg body weight of M. senegalensis extract. Conclusion The implications of these findings is that M. senegalensis ethanolic root bark extract possess potent antiplasmodial effect and may, therefore, serve as potential sources of safe, effective and affordable anti-malarial drugs. The displayed high in vivo antiplasmodial activity and lack of toxic effect render M. senegalensis a candidate for the bioassay-guided isolation of compounds which could develop into new lead structures and candidates for drug development programmes against human malaria.

Vitus Nyigo,1 Andrew Kilale,2 Stella Kilima,1 Elizabeth H Shayo,1 Kesheni P Senkoro,1 Jonathan Mshana,1 Adiel K Mushi,1 Lucas Matemba,1 Julius Massaga11National Institute for Medical Research, 2Muhimbili Medical Research Centre, National Institute for Medical Research, Dar es Salaam, Tanzania Introduction: According to the 2011–2012 HIV and Malaria Indicator Survey, the prevalence of HIV infection in Tanzania is 5.1%, with limited information on its magnitude among older people, as the community believes that the elderly are not at risk. Consequently, little attention is given to the fight against HIV and AIDS in this group. The present study investigated the magnitude of HIV and AIDS infection among older people in rural and urban areas of the Tanzania mainland. Subjects and methods: The study was conducted in Mufindi and Babati districts of Iringa and Manyara regions, respectively, through multistage sampling procedures. Dried blood spot cards were used to collect blood samples for HIV testing among consenting participants. HIV testing was done and retested using different enzyme-linked immunosorbent assay kits. Results: A total of 720 individuals, 340 (47.2%) males and 380 (52.8%) females, were randomly selected, of whom 714 (99.2%) consented to HIV testing while six (0.8%) refused to donate blood. The age ranged from 50 to 98 years, with a mean age of 64.2 years. Overall, a total of 56 (7.8%) participants were HIV-positive. Females had a higher prevalence (8.3%) than males (7.4%), with Mufindi district recording the higher rate (11.3%) compared to the 3.7% of Babati district. The prevalence was higher in the rural population (9.4%) compared to 6.4% of their urban counterparts. Conclusion: Although HIV/AIDS is considered a disease of individuals aged 15–49 years, the overall prevalence among the older people aged 50 years and above for Mufindi and Babati districts was higher than the national prevalence in the general population. These findings point to the need to consider strengthening interventions targeting older populations against HIV/AIDS in these districts while establishing evidence countrywide to inform policy decisions.

Background: Many households in sub-Saharan Africa utilize the private sector as a primary source of treatment for malaria episodes. Expanding access to effective treatment in private drug shops may help reduce incidence of severe disease and mortality. This research leveraged a longitudinal survey of stocking of subsidized artemisinin combination therapies (ACTs), an effective anti-malarial, in Accredited Drug Dispensing Outlets (ADDOs) in two regions of Tanzania. This provided a unique opportunity to explore shop and market level determinants of product diffusion in a developing country retail market. Methods: 356 ADDOs in the Rukwa and Mtwara regions of Tanzania were surveyed at seven points between Feb 2011 and May 2012. Shop level audits were used to measure the availability of subsidized ACTs at each shop. Data on market and shop level factors were collected during the survey and also extracted from GIS layers. Regression and network based methodologies were used. Shops classified as early and late adopters, following Rogers’ model of product diffusion, were compared. The Bass model of product diffusion was applied to determine whether shops stocked ACTs out of a need to imitate market competitors or a desire to satisfy customer needs. Results: Following the introduction of a subsidy for ACTs, stocking increased from 12% to nearly 80% over the seven survey rounds. Stocking was influenced by higher numbers of proximal shops and clinics, larger customer traffic and the presence of a licensed pharmacist. Early adopters were characterized by a larger percentage of customers seeking care for malaria, a larger catchment and sourcing from specific wholesalers/suppliers. The Bass model of product diffusion indicated that shops were adopting products in response to competitor behavior, rather than customer demand. Conclusions: Decisions to stock new pharmaceutical products in Tanzanian ADDOs are influenced by a combination of factors related to both market competition and customer demand, but are particularly influenced by the behavior of competing shops. Efforts to expand access to new pharmaceutical products in developing country markets could benefit from initial targeting of high profile shops in competitive markets and wholesale suppliers to encourage faster product diffusion across all drug retailers.

In order to assess the availability of Emergency Obstetric and Neonatal Care (EmONC) services in Tanzania Mainland, a Cross-sectional survey of a National sample of obstetric care facilities was conducted in 2015. We adapted the Averting Maternal Deaths and Disabilities (AMDD) tool and did spatial mapping using a calibrated Global Positioning System (GPS) Essential Software for Android and Arc Geographical Information System (GIS) software. Data were analysed using STATA, SPSS and Excel computer programs. Ethical approval was granted by the National Institute for Medical Research and the Ministry of Health, Community Development, Gender, Elderly and Children. We identified 5207 obstetric care facilities which is equivalent to 59.7 facilities per 500,000 population. We surveyed 2405 (46.2%) facilities of which 251 (10.4%) had provided all the 7 Basic Emergency Obstetric and Neonatal Care (BEmONC) in past 3 months. Among these, 130 had provided Comprehensive Emergency Obstetric and Neonatal Care (CEmONC). The UN benchmarks for BEmONC and CEmONC facility densities were attained or exceeded by 40% and 76% in all 25 regions respectively. EmONC facilities were dominated by hospitals and were clustered in cities and townships. In conclusions, the distribution of EmONC facilities in Tanzania Mainland is suboptimal in more than half of regions with clustering around cities and townships.

Tanzania’s Primary Health Services Development Program (PHSDP) started in 2007 with the aim to establish and staff an additional 5162 dispensaries, 2074 health centres and 8 district hospitals by 2017 which would implicitly increase obstetric care facility density. However, currently obstetric care facility density is not a standard Emergency Obstetric and Neonatal Care (EmONC) indicator and data on its correlation with the standard EmONC indicators is scanty. In 2015 a cross-sectional survey of all hospitals, health centres and a random sample of dispensaries providing delivery services in all the 25 regions of Tanzania Mainland was conducted whereby the presence of EmONC functions in past 3 months was assessed using a standard tool. Where necessary, population data were based on the 2012 National housing and population Census and the 2010 Tanzania Demographic Health Survey (TDHS). Data were analyzed using IBM SPSS version 20 and STATA. Spatial Mapping was done using a calibrated Geographic Positioning System (GPS) Essential Software for Android and coordinates represented on digitalized map with Arc Geographic Information System (GIS). Ethical approval was granted by the Ethical Clearance Committee of Medical Research Council [MRCC], National Institute for Medical research. Of the confirmed 5207 obstetric care facilities 2405 (46.2%) were surveyed including 35.3% of all dispensaries. National Obstetric care facility density was 68/ 500,000 population, 7/500,000 of them provided all the 7 Basic Emergency Obstretic and Neonatal Care (BEmONC) functions in past 3 months. Among all the regions, 40% had attained or exceeded the international benchmark for EmONC facilities per 500,000 population. Institutional delivery rate was 79% and overall Caesarean Section rate was 5.6%. Improved obstetric care facility density was strongly correlated with improved institutional delivery; Caesarean section rate and met need for EmONC but not the quality of case management. In conclusion obstetric care facility density is well correlated with other standard EmONC indicators.

Essential oils from three plant species growing in Dar es Salaam, Tanzania, Ocimum gratissimum (OG), Ocimum tenuiflorum (OT) and Hyptis suaveolens (HS) all from family Labiateae, were extracted by hydrodistillation and evaluated for laboratory and field based repellency against afro-tropical vectors of malaria and lymphatic filariasis. All oils were found to exhibit high mosquito repellency activity against Anopheles gambiae sensu stricto in the laboratory tests with RC50 values ranging from 2.0- to 15-×10−5 mg cm−2, whereas standard N,N-diethyl- 3-toluamide (DEET) was more repelling with RC50 value of 0.1×10−5mg cm−2. The formulation containing 10% of O. gratissimum provided protection against mosquito bites from Anopheles funestus of 70.5 to 95.7%, A. gambiae of 63.2 to 91.5% andCulex quinquefasciatus of 83.8 to 89.5%. The 30% O. gratissimum formulation was more effective with better protection against mosquito bites from A. funestus of 84.2 to 96.6%, A. gambiae of 73.7 to 91.5% and C. quinquefasciatus of 89.5 to 91.5%. The formulation containing 15% DEET showed slightly lower protection against mosquito bites from A. funestus of 70.5 to 78.9%, A. gambiae of 68.4 to 94.0%, C. quinquefasciatus of 85.5 to 89.5% (P

Male circumcision (MC) has been practiced worldwide for religious, cultural, social and medical reasons. Recent studies in Africa have indicated that MC to be highly protective against HIV transmission. However, incorporating MC in HIV/AIDS prevention programme will increase its demand in Tanzania where traditional male circumcision is common and the health care system is weak. The objective of this study was to determine the challenges and opportunities of involving traditional practitioners in scaling up safe MC in the context of HIV prevention in Tanzania. The study was conducted in Monduli, Bahi and Mkuranga districts of Tanzania. Both quantitative and qualitative methods were employed. Household survey involved community members from the selected villages. In-depth interviews involved traditional practitioners and key informants at national, district and facility levels. A total of 601 householders were interviewed. Most (71.4%) household respondents preferred traditional MC as it was part of their culture and tradition. A similar response was obtained from other respondents. It was mostly preferred because it was used as an initiation school, turning of boys to warriors and sense of social cohesion. Only 228 (37.9%) of the respondents were aware of the adverse events associated with MC. The most frequently mentioned adverse effects were severe bleeding (65.0%), delayed wound healing (17.5%) and wound sepsis (8.4%). The risk of acquiring HIV through male circumcision practice was poorly known among community members except medical respondents. Single unsterilized local surgical equipment was used to circumcise several initiates. It was observed that interference with traditional values associated with circumcision to be the main hindrance of linkage between traditional and conventional practitioners. On the other hand it was reported that there was no policy or guidelines on Traditional MC (TMC). Most of respondents supported the efforts to establish and promote formal linkages between traditional and conventional practitioners. In conclusion, under the current HIV pandemic and TMC being prevalent in Tanzania, it is high time for the government to establish a linkage between traditional and conventional practitioners for safe practices in order to minimize HIV transmission.

Background : Rapid malaria diagnostic tests (RDTs) are non microscopic tests that provide a rapid detection of malaria parasites in infected individuals; they are simple and less technical demanding. However they have low detection thresholds particularly in low parasitaemia. Objectives: To compare and evaluate the performance of ParaHit and OptiMAL tests for detection of malaria infections with routine microscopy. Materials and Methods: Blood samples from study participants were obtained after their informed consent and tested for malaria parasite infection for the two RDTs according to instructions from the manufacturers, blood films were made and stained with Giemsa for microscopy. Results: A total of 243 individuals participated in the study with a median age of 22.0 yrs (range 0 -75yrs). Microscopy had a higher detection rate of 19.7% (48/243) as compared to ParaHit 4.5% and OptiMAL 3.7%. Low sensitivity of 21.2% and 17%, but high specificity of 99.4% with both ParaHit and OptiMAL tests were respectively obtained. Of all positive blood slides for P. falciparum malaria, 78.7% of these smears had low parasite density ranged between 80 -720 parasite/µl of blood. These slides were negative for malaria parasite based on both RDTs. Over 80% of study participants who reported fever had negative blood slides for malaria parasites by microscopy, but 44.7% among those who reported no fever had positive blood slides for P. falciparum Malaria. Study participants who reported to have fever and high parasite density above 720 parasite/µl were likely to be positive by both RDTs (OR= 6.8), P= 0.031529. Conclusions: The overall performance of both RDTs in detecting asexual P. falciparum was low as compared to microscopy and their performance were highly affected with parasite density calling for further evaluation studies before its wide use in peripheral health facilities in order to minimize potential severe consequences.

Objective To assess the validity of health facility (HF)-based data on bednet and insecticide-treated bednet possession and use by children5 years old. Methods We compared estimates based on data collected via HF surveys of under-5s attending well-child visits (e.g. immunizations) and sick-child visits vs. representative household surveys (a 'gold standard' method for measuring insecticide-treated net coverage). In Lindi region, Tanzania, we collected contemporaneous data on 637 under-5s via a HF survey (444 well-child visits and 193 sick-child visits), and on 305 households with an under-5 (including 354 children) via a household survey. In Rufiji district, Tanzania, we collected contemporaneous data on 1433 under-5s via a HF survey (911 well-child visits and 522 sick-child visits), and on 328 households with an under-5 (including 455 children) via a household survey. Results Possession of bednets by households with an under-5 was similar using HF data and household data in both Lindi region and Rufiji district. However, reported use of bednets was significantly higher in HF data than household data in both Lindi and Rufiji, as was reported use of insecticide-treated bednets. HF-based data accurately estimated community-level bednet possession in households with an under-5, but overestimated community-level bednet use by 9-35% and insecticide-treated bednet use by 15-21%. Conclusions Information bias rather than selection bias appears to be a key cause for the overestimation of bednet and insecticide-treated bednet use (e.g. social desirability bias: caretakers of under-5s attending health facilities might be more likely to report using bednets and insecticide-treated bednets). Additional studies of the validity, cost and utility of HF-based data to monitor insecticide-treated bednet use are needed before recommending this monitoring strategy for widespread use. Overestimating insecticide-treated bednet use could lead to inappropriate public health actions and missed opportunities for achieving local and global public health goals.

Use of insecticide-treated bednets (ITNs) to prevent malaria remains low, and effective distribution strategies are needed. An integrated child health campaign with free distribution of 162,254 untreated bednets bundled with insecticide, measles vaccination, vitamin A, and mebendazole for children5 years old ("under-5s") was conducted in Lindi Region, Tanzania. We conducted a representative household survey 3 months after the campaign. Altogether, 574 households with 354 under-5s were visited. In households with an under-5, possession of bednets and ITNs increased from 60.9% to 90.7% (P0.001) and from 16.5% to 37.3% (P0.001), respectively. Increases occurred in all wealth quintiles and equity improved. Reported bednet and ITN use the previous night among under-5s was 46.3% and 21.5%, respectively. Integrated campaigns rapidly and equitably increase bednet possession and use meriting continued large-scale implementation. However, our study found that bednets were rarely treated; thus, future campaigns should provide factory-treated long-lasting ITNs. Low ITN use underscores the need for further efforts to increase use after campaigns.

Vital registration of causes of death in Tanzania is incomplete and many deaths occur outside health care settings. Verbal autopsies (VA) are used to determine the underlying cause of death, and the probable diagnosis helps to estimate reasonably cause-specific mortality. In this paper, we report findings of a verbal autopsy survey which involved eight villages in both low and highlands of Muheza district, north-eastern Tanzania. The survey was conducted following a rapid census, which was done to identify households that had lost one or more members within a period of two years from the date of census. Trained research assistants administered VA questionnaires to parents/close relatives. Two physicians reviewed each report independently and a third opinion was sought where there was discordant report between the two. A total of 9,872 households were surveyed and 134 deaths were recorded. A total of 96 (71.6%) deaths were from lowland villages representing high malaria transmission. Majority (72.4%) of the reported deaths occurred at home whilst 32.1% occurred at heath facility settings. Overall, severe malaria was the leading cause accounting for 34.3% of all deaths. Infants were most affected and accounted for 43.5% of the total deaths. Pulmonary tuberculosis ranked second (8.2%) cause of deaths and was exclusively confined to individuals ≥15 years. Probable cause of death could not be determined in 13.4% of deaths. In conclusion, majority of deaths in rural north-eastern Tanzania occur at home and the immediate causes are usually unknown or not documented. These findings indicate that the verbal autopsy is a useful tool for detecting leading causes of death at community level in the absence of health facility-based data.

A review of plague records from 1986 to 2002 and household interviews were carried out in the plague endemic villages to establish a pattern and spatial distribution of the disease in Lushoto district, Tanzania. Spatial data of households and village centres were collected and mapped using a hand held Global Positioning System and Geographical Information System. During the 16-year period, there were 6249 cases of plague of which 5302 (84.8%) were bubonic, 391 (6.3%) septicaemic, and 438 (7.0%) pneumonic forms. A total of 118 (1.9%) cases were not categorized. Females and individuals aged 7-18 years old were the most affected groups accounting for 54.4% (95% CI: 52.4–56.0) and 47.0% (95% CI: 45–49) of all reported cases, respectively. Most cases were found in villages at high altitudes (1700-1900m); and there was a decline in case fatality rate (CFR) in areas that experienced frequent outbreaks. Overall, there was a reduction in mean reporting time (from symptoms onset to admission) to an average of 1.35 days (95% CI: 1.30–1.40) over the years, although this remained high among adult patients (>18 years). Despite the decrease in the number of cases and CFR over the years, our findings indicate that Lushoto district experiences human plague epidemic every year; with areas at high altitudes being more prone to outbreaks. The continued presence of plague in this focus warrants further studies. Nonetheless, our findings provide a platform for development of an epidemic preparedness plan to contain future outbreaks..

A cross-sectional survey was conducted in Kwelumbizi and Shambangeda villages, in the East Usambara Mountains, in north-east Tanzania, to determine the prevalence of malaria parasitaemia and nutritional status in children ≤ 11 years old. In addition, knowledge and practice on malaria among the households were determined using questionnaires and focus group discussions. The results showed that prevalence of malaria (48.5 - 51.0%) and parasite density levels was similar in both villages. A significantly higher malaria prevalence was observed in children ≥ 5 years old than in the < 5 years old (P=0.01). This correlated with the higher spleen rate in the same age group (P=0.022). However, higher anaemia prevalence (both severe and moderate), lower haemoglobin levels were found in children < 5 years old. There was no variation in most of the clinical history/symptoms among children with malaria in the two villages. However, coughing (P=0.014) was frequently observed among children in Shambangeda. The use of mosquito nets was more common among the residents of Shambangeda than Kwelumbizi (P=0.001). Children ≥ 5 years old were significantly malnourished in all levels of measurement. Wasting was more frequently observed among females in the < 5year old while stunting and underweight were more observed among males in all age groups. Malaria, anaemia and malnutrition are prevalent in the East Usambara Mountains. Efforts to address these conditions are urgently needed.

Background: The National Institute for Medical Research, Amani centre, in collaboration with National Malaria Control Programme, has been conducting annual insecticide resistance surveillance since 1999, aimed at early detection of resistance to insecticides used for malaria control in Tanzania. The Standard WHO method for larvae collection and rearing were used but challenges and limitations were encountered. For example rearing the larvae and adult mosquitoes using the Standard WHO method experienced 100% mortality for larvae; and adults in three days. The researchers therefore made modifications to the Standard WHO method to create suitable tools for the field environment. Methods: A ladle was created from an empty water bottle in which an oval hole longitudinally cut halfway from the bottom. Instead of using TetraMin as mosquito larval food, green algae were collected from mosquito breeding sites and used as larval food. Improvised heater of charcoal stoves and humidifier of wet fabric such as “Kanga” and “Kitenge” were also used. Results and conclusion: There was 90% larval survival, adult mosquito survived much better and the scientists had a total of 467 mosquitoes to run the insecticide susceptibility tests. Innovative ways are necessary under field conditions for mosquito breeding in susceptibility studies.

Background The HIV/AIDS pandemic remains a leading challenge for global health. Although condoms are acknowledged for their key role on preventing HIV transmission, low and inappropriate use of condoms persists in Tanzania and elsewhere in Africa. This study assesses factors affecting acceptability of condom promotion and distribution among adolescents in Mpwapwa and Mbeya rural districts of Tanzania. Methods Data were collected in 2011 as part of a larger cross-sectional survey on condom use among 10–19 year-olds in Mpwapwa and Mbeya rural districts of Tanzania using a structured questionnaire. Associations between acceptability of condom promotion and distribution and each of the explanatory variables were tested using Chi Square. Multivariate logistic regression model was used to examine independent predictors of the acceptability of condom promotion and distribution using STATA (11) statistical software at 5% significance level. Results Mean age of the 1,327 adolescent participants (50.5% being males) was 13.5 years (SD = 1.4). Acceptance of condom promotion and distribution was found among 37% (35% in Mpwapwa and 39% in Mbeya rural) of the adolescents. Being sexually active and aged 15–19 was the strongest predictor of the acceptability of condom promotion and distribution (OR = 7.78, 95% CI 4.65-12.99). Others were; not agreeing that a condom is effective in preventing transmissions of STIs including HIV (OR = 0.34, 95% CI 0.20-0.56), being a resident of Mbeya rural district (OR = 1.67, 95% CI 1.28-2.19), feeling comfortable being seen by parents/guardians holding/buying condoms (OR = 2.20, 95% CI 1.40-3.46) and living with a guardian (OR = 1.48, 95% CI 1.08-2.04). Conclusion Acceptability of condom promotion and distribution among adolescents in Mpwapwa and Mbeya rural is low. Effect of sexual activity on the acceptability of condom promotion and distribution is age-dependent and was the strongest. Feeling comfortable being seen by parents/guardians buying or holding condoms, perceived ability of condoms to offer protection against HIV/AIDS infections, district of residence and living arrangements also offered significant predictive effect. Knowledge of these factors is vital in designing successful and sustainable condom promotion and distribution programs in Tanzania.

In order to use a combination of ivermectin and albendazole for the elimination of lymphatic filariasis, it is important to assess the potential risk of increased adverse events in individuals infected with both lymphatic filariasis and onchocerciasis. We compared the safety and efficacy of albendazole (400 mg) in combination with ivermectin (150 micrograms/kg), for the treatment of co-infections of Wuchereria bancrofti and Onchocerca volvulus with single infection of W. bancrofti. The safety study on co-infections was a crossover, double blind design, while for the single infection of bancroftian filariasis an open design comparing two treatments was used. For co-infection, one group was allocated a single dose of ivermectin (150 micrograms/kg) plus albendazole (400 mg) (Group A). The other group received placebo (Group B). Five days later the treatment regime was reversed, with the Group A receiving placebo and Group B receiving treatment. For the single bancroftian filariasis infection, one group received a single dose of albendazole (400 mg) plus ivermectin (150 μg/kg) (Group C) while the other group received a single dose of albendazole (400 mg) alone (Group D). Blood and skin specimens were collected on admission day, day 0, and on days 2, 3, and 7 to assess drug safety and efficacy. Thereafter, blood and skin specimens were collected during the 12 months follow up for the assessment of drug efficacy. Study individuals were clinically monitored every six hours during the first 48 hours following treatment, and routine clinical examinations were performed during the hospitalisation period and follow-up. In individuals co-infected with bancroftian filariasis and onchocerciasis, treatment with ivermectin and albendazole was safe and tolerable. Physiological indices showed no differences between groups with co-infection (W. bancrofti and O. volvulus) or single infection (W. bancrofti). The frequency of adverse events in co-infected individuals was 63% (5/8, Group A, albendazole + ivermectin) and 57% (4/7, Group B, placebo) and of mild or moderate intensity. In single W. bancrofti infection the frequency of adverse events was 50% (6/12, Group C, albendazole + ivermectin) and 38% (5/13, Group D, albendazole) and of a similar intensity to those experienced with co-infection. There were no differences in adverse events between treatment groups. There was no significant difference in the reduction of microfilaraemia following treatment with albendazole and ivermectin in groups with single or co-infection. Our findings suggest that ivermectin plus albendazole is a safe and tolerable treatment for co-infection of bancroftian filariasis and onchocerciasis.

Background Roll-out and implementation of antiretroviral therapy (ART) necessitated many countries in Sub-Saharan Africa to strengthen their national health laboratory systems (NHLSs) to provide high quality HIV diagnostic and supportive services. This study was conducted to assess the performance of health laboratories in provision of HIV diagnostic and supportive services in eight districts (from four regions of Iringa, Mtwara, Tabora and Tanga), after nine years of implementation of HIV/AIDS care and treatment plan in Tanzania. Methods In this cross-sectional study, checklists and observations were utilized to collect information from health facilities (HFs) with care and treatment centres (CTCs) for HIV/AIDS patients; on availability of laboratories, CTCs, laboratory personnel, equipment and reagents. A checklist was also used to collect information on implementation of quality assurance (QA) systems at all levels of the NHLS in the study areas. Results The four regions had 354 HFs (13 hospitals, 41 Health Centres (HCs) and 300 dispensaries); whereby all hospitals had laboratories and 11 had CTCs while 97.5 and 61.0% of HCs had both laboratories and CTCs, respectively. Of the dispensaries, 36.0 and 15.0% had laboratories and CTCs (mainly in urban areas). Thirty nine HFs (12 hospitals, 21 HCs and six dispensaries) were assessed and 56.4% were located in urban areas. The assessed HFs had 199 laboratory staff of different cadres (laboratory assistants = 35.7%; technicians =32.7%; attendants = 22.6%; and others = 9.1%); with >61% of the staff and 72.3% of the technicians working in urban areas. All laboratories were using rapid diagnostic tests for HIV testing. Over 74% of the laboratories were performing internal quality control and 51.4% were participating in external QA programmes. Regional and district laboratories had all key equipment and harmonization was maintained for Fluorescence-Activated Cell Sorting (FACS) machines. Most of the biochemical (58.0%) and haematological analysers (74.1%) were available in urban areas. Although >81% of the equipment were functional with no mechanical faulty, 62.6% had not been serviced in the past three years. Conclusion Diagnostic and supportive services for HIV were available in most of the HCs and hospitals while few dispensaries were providing the services. Due to limitations such as shortage of staff, serving of equipment and participation in QA programmes, the NHLS should be strengthened to ensure adequate human resource, implementation of QA and sustainable preventive maintenance services of equipment.

BACKGROUND: Malaria continues to top the list of the ten most threatening diseases to child survival in Tanzania. The country has a functional policy for appropriate case management of malaria with rapid diagnostic tests (RDTs) from hospital level all the way to dispensaries, which are the first points of healthcare services in the national referral system. However, access to these health services in Tanzania is limited, especially in rural areas. Formalization of trained village health workers (VHWs) can strengthen and extend the scope of public health services, including diagnosis and management of uncomplicated malaria in resource-constrained settings. Despite long experience with VHWs in various health interventions, Tanzania has not yet formalized its involvement in malaria case management. This study presents evidence on acceptability of RDTs used by VHWs in rural northeastern Tanzania. METHODS: A cross-sectional study using quantitative and qualitative approaches was conducted between March and May 2012 in Pangani district, northeastern Tanzania, on community perceptions, practices and acceptance of RDTs used by VHWs. RESULTS: Among 346 caregivers of children under 5 years old, no evidence was found of differences in awareness of HIV rapid diagnostic tests and RDTs (54 vs. 46 %, p = 0.134). Of all respondents, 92 % expressed trust in RDT results, 96 % reported readiness to accept RDTs by VHWs, while 92 % expressed willingness to contribute towards the cost of RDTs used by VHWs. Qualitative results matched positive perceptions, attitudes and acceptance of mothers towards the use of RDTs by VHWs reported in the household surveys. Appropriate training, reliable supplies, affordability and close supervision emerged as important recommendations for implementation of RDTs by VHWs. CONCLUSION: RDTs implemented by VHWs are acceptable to rural communities in northeastern Tanzania. While families are willing to contribute towards costs of sustaining these services, policy decisions for scaling-up will need to consider the available and innovative lessons for successful universally accessible and acceptable services in keeping with national health policy and sustainable development goals.

Background Correct diagnosis of malaria is crucial for proper treatment of patients and surveillance of the disease. However, laboratory diagnosis of malaria in Tanzania is constrained by inadequate infrastructure, consumables and insufficient skilled personnel. Furthermore, the perceptions and attitude of health service providers (laboratory personnel and clinicians) and users (patients/care-takers) on the quality of laboratory services also present a significant challenge in the utilization of the available services. This study was conducted to assess perceptions of users and health-care providers on the quality and utilization of laboratory malaria diagnostic services in six districts from three regions in Tanzania. Methods Questionnaires were used to collect information from laboratory personnel, clinicians and patients or care-takers. Results A total of 63 laboratory personnel, 61 clinicians and 753 patients/care-takers were interviewed. Forty-six (73%) laboratory personnel claimed to be overworked, poorly motivated and that their laboratories were under-equipped. About 19% (N = 12) of the laboratory personnel were lacking professional qualification. Thirty-seven clinicians (60.7%) always requested for blood smear examination to confirm malaria. Only twenty five (41.0%) clinicians considered malaria microscopy results from their respective laboratories to be reliable. Forty-five (73.8%) clinicians reported to have been satisfied with malaria diagnostic services provided by their respective laboratories. Majority (90.2%, N = 679) of the patients or care-takers were satisfied with the laboratory services. Conclusion The findings show that laboratory personnel were not satisfied with the prevailing working conditions, which were reported to undermine laboratory performance. It was evident that there was no standard criteria for ordering malaria laboratory tests and test results were under-utilized. Majority of the clinicians and patients or care-takers were comfortable with the overall performance of laboratories, but laboratory results were having less impact on patient management.

Background The Affordable Medicines Facility for malaria (AMFm) is a pilot supra-national subsidy program that aims to increase access and affordability of artemisinin combination therapy (ACT) in public sector clinics and private retail shops. It is unclear to what extent the AMFm model will translate into wide scale availability and price reductions in ACT, particularly for rural, remote areas where disparities in access to medicines often exist. This study is the first to rigorously examine the availability and price of subsidized ACT during the first year of the AMFm, measured through retail audits in remote regions of Tanzania. Methods Periodic retail audits of Accredited Drug Dispensing Outlets (ADDOs) were conducted in two remote regions of Tanzania (Mtwara and Rukwa). Temporal and spatial variation in ACT availability and pricing were explored. A composite measure of ADDO remoteness, using variables, such as distance to suppliers and towns, altitude and population density, was used to explore whether ACT availability and price vary systematically with remoteness. Results Between February 2011 and January 2012, the fraction of ADDOs stocking AMFm-ACT increased from 25% to 88% in Mtwara and from 3% to 62% in Rukwa. Availability was widespread, though diffusion throughout the region was achieved more quickly in Mtwara. No significant relationship was found between ACT availability and remoteness. Adult doses of AMFm-ACT were much more widely available than any other age/weight band. Average prices fell from 1529 TZS (1.03 USD) to 1272 TZS (0.81 USD) over the study period, with prices in Rukwa higher than Mtwara. The government recommended retail price for AMFm- ACT is 1,000 TZS ($0.64 USD). The median retail ACT price in the final round of data collection was 1,000 TZS. Conclusions The AMFm led to large increases in availability of low priced ACT in Tanzania, with no significant variation in availability based on remoteness. Availability did remain lower and prices remained higher in Rukwa, which is a more remote region overall. Low availability of child and adolescent ACT doses could be due in part to lower quantities of non-adult packs imported into Tanzania. Future research will explore whether increased availability and affordability persists and whether it translates into higher ACT use in Tanzania.
