It has been discovered that incorporating technology into geometry instruction improves students' abilities and attitudes. GeoGebra Software is effective at motivating teachers to use technology as a supplement to enhance students' mathematical learning potential. The current study sought to ascertain the effects of GeoGebra software on secondary school students' performance as well as teachers' and students' attitudes toward 3-dimensional geometry. A sample of 84 Senior Five students in upper secondary school from Kicukiro and Musanze District was chosen purposively. The selected sample was divided into two groups for the quasi-experimental design, with the control group having 44 students and the experimental group having 40 students. Additionally, two teachers were chosen to involve in the study. Students in the experimental group used GeoGebra software to study 3D geometry, whereas students in the control group received traditional geometry instruction. The data was collected quantitatively, with both groups taking pre-and post-tests. The obtained data were analyzed using SPSS v.25. The results revealed a statistically significant difference in students' performance between the groups in favour of the experimental group. Furthermore, both teachers' and students' attitudes were improved. These findings support GeoGebra's efficacy in increasing student achievement as well as teachers' and students' attitudes toward 3-D geometry. However, there was no statistically significant difference in attitudes between male and female students, according to the study. Therefore, we advise adding GeoGebra to mathematics curricula across all grade levels in Rwanda, with a focus on geometry.

IntroductionYam is an important crop for food security in East and West Africa due to its high market value and customer demand. High tuber quality with yield and disease resistance are the main traits for acceptability of yam cultivars across the tropical zone. There has been limited progress in enhancing the production and quality traits of yams, despite the significant socio-economic significance of this crop.MethodTo expedite the development of high-quality yam cultivars in Uganda, traits association study was conducted to identify genomic regions associated with key traits such as disease resistance, high yields, and dry matter content. The association mapping was conducted with multi-random mixed linear model (mrMLM) to compute the associations using five genetic models.ResultsA total of 16 significant single nucleotide polymorphisms (SNPs) markers were identified to be associated with the traits studied. Gene identification analysis revealed the presence of key putative genes such as Vicilin-like seed storage protein At2g28490 (ARATH)and Growth-regulating factor 1 involved in a variety of functions ranging from storage and gene regulation for disease resistance.DiscussionThe results obtained from this work have significant implications for the in-depth analysis of the genetic structure underlying key traits in yam. Additionally, this study emphasizes the identification of SNP variants and genes that may be utilized for genomic-informed selection in order to enhance yield and disease resistance in yams.

Despite advances in hookworm control and prevention campaigns, the prevalence remains high in sub-Saharan Africa. Iron deficiency anaemia is a major complication in those with prolonged infection, a high hookworm burden, and undernutrition, though most infected people are asymptomatic. While infected patients are commonly diagnosed by the presence of ova or cysts in the stool, gastrointestinal (GI) endoscopy is required for those with negative stool tests and chronic iron deficiency anaemia. A 48-year-old female with symptoms of anaemia for nearly two years presented to Mbarara Regional Referral Hospital with worsening palpitations, easy fatigability, and dizziness over a period of one month. She was given blood transfusions on two occasions. She lives near the lake where she also gets water for drinking and domestic use. We advise GI endoscopy for all patients with chronic iron deficiency anaemia of unexplained aetiology on standard non-invasive testing. Hookworm’s mass empirical treatment policy in endemic areas should be further emphasised.

Abstract Background Piggery production is highly constrained by diseases, with diarrhoea in piglets being a major cause of economic losses to smallholder farmers in Uganda. Enterotoxigenic Escherichia coli (ETEC) is thought to be one of the major etiologies of this diarrhoea. A cross-sectional study was carried out in two high pig-producing districts of Uganda with the aim of determining the significance of piglet diarrhoea and the pathogenic determinants of causative E. coli. Methodology A total of 40 households with piglets were visited in each district for a questionnaire survey and faecal sample collection. The questionnaire-based data collected included; demographic data and pig management practices. E. coli were isolated from diarrheic (43) and non-diarrheic (172) piglets and were subjected to antimicrobial susceptibility testing against nine commonly used antimicrobial agents. The E. coli isolates were further screened for the presence of 11 enterotoxin and fimbrial virulence gene markers using multiplex polymerase chain reaction. Data entry, cleaning, verification and descriptive statistics were performed using Microsoft Excel. Statistical analysis to determine any association between the presence of virulence markers and diarrhea in piglets was done using SPSS software (Version 23), with a p value of less than 0.05 taken as a statistically significant association. Results Escherichia coli were recovered from 81.4% (175/215) of the faecal samples. All the isolates were resistant to erythromycin, and most showed high resistance to tetracycline (71%), ampicillin (49%), and trimethoprim sulfamethoxazole (45%). More than half of the isolates (58.3%) carried at least one of the 11 virulence gene markers tested. EAST1 was the most prevalent virulence marker detected (35.4%), followed by STb (14.8%). Expression of more than one virulence gene marker was observed in 6.2% of the isolates, with the EAST1/STa combination being the most prevalent. Three adhesins; F17 (0.6%), F18 (6.3%) and AIDA-I (0.6%) were detected, with F18 being the most encountered. There was a statistically significant association between the occurrence of piglet diarrhoea and the presence of the AIDA-1 (p value = 0.037) or EAST1 (p value = 0.011) gene marker among the isolates. Conclusion and recommendation The level of antimicrobial resistance among E. coli isolates expressing virulence markers were high in the sampled districts. The study established a significant association between presence of EAST1 and AIDA-I virulence markers and piglet diarrhea. Further studies should be carried out to elucidate the main adhesins borne by these organisms in Uganda and the actual role played by EAST1 in the pathogenesis of the infection since most isolates expressed this gene.

Abstract Reverse zoonotic respiratory diseases threaten great apes across Sub-Saharan Africa. Studies of wild chimpanzees have identified the causative agents of most respiratory disease outbreaks as “common cold” paediatric human pathogens, but reverse zoonotic transmission pathways have remained unclear. Between May 2019 and August 2021, we conducted a prospective cohort study of 234 children aged 3–11 years in communities bordering Kibale National Park, Uganda, and 30 adults who were forest workers and regularly entered the park. We collected 2047 respiratory symptoms surveys to quantify clinical severity and simultaneously collected 1989 nasopharyngeal swabs approximately monthly for multiplex viral diagnostics. Throughout the course of the study, we also collected 445 faecal samples from 55 wild chimpanzees living nearby in Kibale in social groups that have experienced repeated, and sometimes lethal, epidemics of human-origin respiratory viral disease. We characterized respiratory pathogens in each cohort and examined statistical associations between PCR positivity for detected pathogens and potential risk factors. Children exhibited high incidence rates of respiratory infections, whereas incidence rates in adults were far lower. COVID-19 lockdown in 2020–2021 significantly decreased respiratory disease incidence in both people and chimpanzees. Human respiratory infections peaked in June and September, corresponding to when children returned to school. Rhinovirus, which caused a 2013 outbreak that killed 10% of chimpanzees in a Kibale community, was the most prevalent human pathogen throughout the study and the only pathogen present at each monthly sampling, even during COVID-19 lockdown. Rhinovirus was also most likely to be carried asymptomatically by adults. Although we did not detect human respiratory pathogens in the chimpanzees during the cohort study, we detected human metapneumovirus in two chimpanzees from a February 2023 outbreak that were genetically similar to viruses detected in study participants in 2019. Our data suggest that respiratory pathogens circulate in children and that adults become asymptomatically infected during high-transmission times of year. These asymptomatic adults may then unknowingly carry the pathogens into forest and infect chimpanzees. This conclusion, in turn, implies that intervention strategies based on respiratory symptoms in adults are unlikely to be effective for reducing reverse zoonotic transmission of respiratory viruses to chimpanzees.

Abstract Introduction Victimisation of persons with severe mental illness is recognised as an urgent global concern, with literature pointing to higher rates of violent victimisation of persons with severe mental illness than those of the general population. Yet, for low income countries, there is a huge gap in the literature on the risk, character and victims’ in-depth experiences of victimisation of persons with severe mental illness. We explore the lived experiences and meanings of victimisation of persons with severe mental illness in Uganda, and discuss their implications for care of the mentally ill. Methods A pluralistic qualitative study was undertaken to explore victimisation among patients with severe mental illness. Patients who had suffered victimisation were purposively sampled from Butabika National Referral Mental Clinic and Masaka Regional Referral Hospital, following confirmation of symptom remission. In-depth interviews were held with 18 participants, comprising 13 females and 5 males from low to moderate socioeconomic status. Interpretative phenomenological analysis and thematic content analysis were conducted. Results Victimisation was exhibited in three main forms: (a) psychological, expressed in attitudes towards mentally ill family members as valueless and dispensable, and stigmatisation, (b) physical, as manifested in beatings, indoor confinement and tethering mostly by family members and (c) sexual victimisation, particularly rape. Also observed were victim’s various responses that pointed to the negative impact of victimisation, including a heightened risk of suicide, social withdrawal, a sense of hatefulness and a predisposition to more victimisation. Conclusion The family environment plays a predominant role in perpetrating victimisation of the mentally ill in some sub-Saharan African contexts such as Uganda. We propose a holistic framework for mental health interventions, incorporating biomedical but notably also social determinants of mental health, and targeted at improving familial relationships, social support and a sense of belongingness both within the family and the broader community.

IntroductionRespiratory illness is the most common childhood disease globally, especially in developing countries. Previous studies have detected viruses in approximately 70-80% of respiratory illnesses.MethodsIn a prospective cohort study of 234 young children (ages 3-11 years) and 30 adults (ages 22-51 years) in rural Western Uganda sampled monthly from May 2019 to August 2021, only 24.2% of nasopharyngeal swabs collected during symptomatic disease had viruses detectable by multiplex PCR diagnostics and metagenomic sequencing. In the remaining 75.8% of swabs from symptomatic participants, we measured detection rates of respiratory bacteria Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae by quantitative PCR.Results100% of children tested positive for at least one bacterial species. Detection rates were 87.2%, 96.8%, and 77.6% in children and 10.0%, 36.7%, and 13.3% for adults for H. influenzae, M. catarrhalis, and S. pneumoniae, respectively. In children, 20.8% and 70.4% were coinfected with two and three pathogens, respectively, and in adults 6.7% were coinfected with three pathogens but none were coinfected with two. Detection of any of the three pathogens was not associated with season or respiratory symptoms severity, although parsing detection status by symptoms was challenged by children experiencing symptoms in 80.3% of monthly samplings, whereas adults only reported symptoms 26.6% of the time. Pathobiont colonization in children in Western Uganda was significantly more frequent than in children living in high-income countries, including in a study of age-matched US children that utilized identical diagnostic methods. Detection rates were, however, comparable to rates in children living in other Sub-Saharan African countries.DiscussionOverall, our results demonstrate that nonviral colds contribute significantly to respiratory disease burden among children in rural Uganda and that high rates of respiratory pathobiont colonization may play a role. These conclusions have implications for respiratory health interventions in the area, such as increasing childhood immunization rates and decreasing air pollutant exposure.

ABSTRACT Africa has over 2000 languages; however, those languages are not well represented in the existing natural language processing ecosystem. African languages lack essential digital resources to effectively engage in advancing language technologies. There is a need to generate high‐quality natural language processing resources for low‐resourced African languages. Obtaining high‐quality speech and text data is expensive and tedious because it can involve manual sourcing and verification of data sources. This paper discusses the process taken to curate and annotate text and speech datasets for five East African languages: Luganda, Runyankore‐Rukiga, Acholi, Lumasaba, and Swahili. We also present results obtained from baseline models for machine translation, topic modeling and classification, sentiment classification, and automatic speech recognition tasks. Finally, we discuss the experiences, challenges, and lessons learned in creating the text and speech datasets.

IntroductionRespiratory disease is a major cause of morbidity and mortality in the developing world, but prospective studies of temporal patterns and risk factors are rare.MethodsWe studied people in rural Western Uganda, where respiratory disease is pervasive. We followed 30 adults (ages 22–51 years; 534 observations) and 234 children (ages 3–11 years; 1,513 observations) between May 2019 and July 2022 and collected monthly data on their respiratory symptoms, for a total of 2,047 case records. We examined associations between demographic and temporal factors and respiratory symptoms severity.ResultsThe timing of our study (before, during, and after the emergence of COVID-19) allowed us to document the effects of public health measures instituted in the region. Incidence rates of respiratory symptoms before COVID-19 lockdown were 568.4 cases per 1,000 person-months in children and 254.2 cases per 1,000 person-months in adults. These rates were 2.6 times higher than the 2019 global average for children but comparable for adults. Younger children (ages 3–6 years) had the highest frequencies and severities of respiratory symptoms. Study participants were most likely to experience symptoms in February, which is a seasonal pattern not previously documented. Incidence and severity of symptoms in children decreased markedly during COVID-19 lockdown, illustrating the broad effects of public health measures on the incidence of respiratory disease.DiscussionOur results demonstrate that patterns of respiratory disease in settings such as Western Uganda resemble patterns in developed economies in some ways (age-related factors) but not in others (increased incidence in children and seasonal pattern). Factors such as indoor air quality, health care access, timing of school trimesters, and seasonal effects (rainy/dry seasons) likely contribute to the differences observed.

Malawi—one of the low-income countries in Africa—has witnessed a series of flood-related disasters in many years. The recent tropical cyclone Freddy (TCF) has indispensable effects on the unequal distribution of the social determinants of health with tendencies for increased disease outbreaks across the districts of the country. This narrative study aimed at unravelling the consequences of the TCF and its possible relationship with the already existing cholera epidemic in the fourteen affected districts. Additionally, it aimed to document the immediate humanitarian responses in the acute phase of the disaster. We identified, used and extracted information and data from relevant documents available from the government records, WHO and other multiagency documents, which were summarised along with the humanitarian actions and the associated implications of the entire event. Areas of TCF’s main effects included health, shelter, education, nutrition, water sanitation and hygiene, agriculture and livelihood, transport and logistics including food security. The notable immediate humanitarian responses are donations, camp creation for accommodations, emergency life-saving response and essential healthcare services. Nsanje and Chikwawa districts experienced an increase in cholera cases and deaths post-TCF. The highest proportion of the disaster-impacted and intervention beneficiaries were women and children. The effects of the TCF on the social determinants of health in the affected districts and the associated negative impacts should be considered by the government and disaster management experts in evidence-based policy-making towards disaster risk reduction in the flood-prone districts using an all-hazard approach. This step might be useful in improving the vulnerable population’s standard of living and achievement of related Sustainable Development Goals in Malawi.

Abstract Background Rift Valley Fever (RVF) is a viral zoonosis that can cause severe haemorrhagic fevers in humans and high mortality rates and abortions in livestock. On 10 December 2020, the Uganda Ministry of Health was notified of the death of a 25-year-old male who tested RVF-positive by reverse-transcription polymerase chain reaction (RT-PCR) at the Uganda Virus Research Institute. We investigated to determine the scope of the outbreak, identify exposure factors, and institute control measures. Methods A suspected case was acute-onset fever (or axillary temperature > 37.5 °C) and ≥ 2 of: headache, muscle or joint pain, unexpected bleeding, and any gastroenteritis symptom in a resident of Sembabule District from 1 November to 31 December 2020. A confirmed case was the detection of RVF virus nucleic acid by RT-PCR or serum IgM antibodies detected by enzyme-linked immunosorbent assay (ELISA). A suspected animal case was livestock (cattle, sheep, goats) with any history of abortion. A confirmed animal case was the detection of anti-RVF IgM antibodies by ELISA. We took blood samples from herdsmen who worked with the index case for RVF testing and conducted interviews to understand more about exposures and clinical characteristics. We reviewed medical records and conducted an active community search to identify additional suspects. Blood samples from animals on the index case’s farm and two neighbouring farms were taken for RVF testing. Results The index case regularly drank raw cow milk. None of the seven herdsmen who worked with him nor his brother’s wife had symptoms; however, a blood sample from one herdsman was positive for anti-RVF-specific IgM and IgG. Neither the index case nor the additional confirmed case-patient slaughtered or butchered any sick/dead animals nor handled abortus; however, some of the other herdsmen did report high-risk exposures to animal body fluids and drinking raw milk. Among 55 animal samples collected (2 males and 53 females), 29 (53%) were positive for anti-RVF-IgG. Conclusions Two human RVF cases occurred in Sembabule District during December 2020, likely caused by close interaction between infected cattle and humans. A district-wide animal serosurvey, animal vaccination, and community education on infection prevention practices campaign could inform RVF exposures and reduce disease burden.

Abstract Background The declaration of SARS-CoV-2 as a public health emergency of international concern in January 2020 prompted the need to strengthen infection prevention and control (IPC) capacities within health care facilities (HCF). IPC guidelines, with standard and transmission-based precautions to be put in place to prevent the spread of SARS-CoV-2 at these HCFs were developed. Based on these IPC guidelines, a rapid assessment scorecard tool, with 14 components, to enhance assessment and improvement of IPC measures at HCFs was developed. This study assessed the level of implementation of the IPC measures in HCFs across the African Region during the COVID-19 pandemic. Method An observational study was conducted from April 2020 to November 2022 in 17 countries in the African Region to monitor the progress made in implementing IPC standard and transmission-based precautions in primary-, secondary- and tertiary-level HCFs. A total of 5168 primary, secondary and tertiary HCFs were assessed. The HCFs were assessed and scored each component of the tool. Statistical analyses were done using R (version 4.2.0). Results A total of 11 564 assessments were conducted in 5153 HCFs, giving an average of 2.2 assessments per HCF. The baseline median score for the facility assessments was 60.2%. Tertiary HCFs and those dedicated to COVID-19 patients had the highest IPC scores. Tertiary-level HCFs had a median score of 70%, secondary-level HCFs 62.3% and primary-level HCFs 56.8%. HCFs dedicated to COVID-19 patients had the highest scores, with a median of 68.2%, followed by the mixed facilities that attended to both COVID-19 and non-COVID-19 patients, with 64.84%. On the components, there was a strong correlation between high IPC assessment scores and the presence of IPC focal points in HCFs, the availability of IPC guidelines in HCFs and HCFs that had all their health workers trained in basic IPC. Conclusion In conclusion, a functional IPC programme with a dedicated focal person is a prerequisite for implementing improved IPC measures at the HCF level. In the absence of an epidemic, the general IPC standards in HCFs are low, as evidenced by the low scores in the non-COVID-19 treatment centres.

Introduction: Emergency medicine (EM) is a new specialty in Uganda. There is no current formal EM undergraduate curriculum. The Mbarara University of Science and Technology Emergency Medicine Interest Group (MUST-EMIG) was established to bridge this gap. This survey was done to assess the contributions of MUST-EMIG. Objectives of the study were to: discover students' reasons for joining the MUST-EMIG; assess whether interest in learning emergency medicine was affected by participation in MUST-EMIG; evaluate plans to pursue emergency medicine as a specialty before and after joining MUST-EMIG; determine whether MUST-EMIG affected students’ perception of emergency medicine's importance in Uganda's health care system; and elicit feedback from students on their experience as members of MUST-EMIG. Methods: The MUST-EMIG executive developed a membership survey which was reviewed by MUST-EMIG's faculty advisor for suitability. Members of MUST-EMIG were voluntarily asked to participate in the online survey. Results of the survey were summarized using descriptive statistics and thematic analysis. Results: 49 responses (46.7% response rate) were collected and analyzed. Participants included 29 (59.2%) male and 20 (40.8%) female medical students. The majority of participants were fourth year students 22 (44.9%). 44 (89.8%) students joined MUST-EMIG to learn how to handle medical emergencies, and expressed a desire of at least 6/10 to learn more about emergency medicine after utilizing opportunities provided by MUST-EMIG. Overall, students had a good experience with MUST-EMIG. They reported that our interest group had provided them networking, unique learning, and leadership opportunities. Having an EMIG significantly affects students’ desire to pursue a career in emergency medicine and their perception of the relevance of emergency medicine. Discussion: An EMIG helps develop interest of medical students in emergency medicine. Students passionate about emergency medicine need to be supported to help them preserve and further develop this passion.

The aim of this study is to establish an in-depth understanding of how art and design teacher educators (TEs) develop digital competences in teacher training institutions in Uganda. The study utilizes perspectives from Jan van Dijk's resources and appropriation theory as a conceptual lens to understand how art and design TEs develop digital competence for teaching in Uganda. Based on a case study design, semi-structured interviews and non-participant observations were employed to gather qualitative data from twenty-four informants who were purposively selected. The informants included ten TEs, ten teacher trainees and four administrators from two teacher training institutions in central Uganda. The findings indicate that art and design TEs develop digital competence through formal approaches, such as "continuous professional development" and "pre-service training," and informal approaches, such as "collaboration," "self-teaching" and "repetition." The empirical findings contribute to the existing body of knowledge and provide an understanding of the development of teachers' digital competence in Uganda.

We implemented GeoGebra software in Rwandan secondary schools to check its effectiveness during teaching and learning geometry concepts. The quasi-experimental design was used, and four schools were purposefully selected. Two schools were from Northern Province, while the other two were selected from Kigali city. A geometry-based test composed of 15 open questions was designed to assess the teaching effect before and after learning geometry. The study was conducted from December 2020 through June 2021 with 87 students. Two schools were assigned as control while the other two as experimental groups. Each group comprised one school from Kigali and one from Northern Province. We analyzed data using SPSS and computed multivariate analysis of variance. We found that students who learned with GeoGebra outperformed those who learned without GeoGebra (M = 77.68% and SD = 14.13 versus M = 56.78% and SD = 15.77, with p < 0.001 and d = 0.254). We also found that the number of students who were able to perform each of the 15 questions increased drastically due to the potential of GeoGebra. The study recommends the use of GeoGebra in all teaching and learning activities of mathematics.

Although the use of digital technologies in teacher education has reached advanced stages in the developed world, it is still in its infancy in many developing countries, including Uganda. In their struggle to advance the use of digital technologies in teaching, educators face various challenges that prevent the successful adoption of such technologies in the classroom. This study explores the motivation and material accessibility challenges that art and design (A&D) educators in Uganda encounter when teaching with digital technologies and examines how they cope with these challenges. To address the research question, the study adopts a descriptive case study design that seeks to document the participants' accounts. Semi-structured interviews and non-participant observations were employed to collect data from teacher educators (TEs) and administrators (ADs) in two teacher training institutions (TTIs) in Uganda. The findings indicate that A&D TEs face accessibility challenges relating to motivation and material access. The educators use various strategies to cope with the existing challenges including peer support, continual practice, improvisation, lobbying for technical and financial support, and advocating for Bring Your Own Device (BYOD).

Abstract We evaluated the diagnostic performance of a qualitative stool antigen test (SAT) in individuals with dyspepsia in rural Uganda using the polymerase chain reaction-based 16S ribosomal RNA assay (16S rRNA) for nucleotide sequences for two common H. pylori-associated genes as the reference standard. We enrolled 150 adults with dyspepsia with no self-reported use of antibiotic and/or antiacid medication medications within a fortnight. We performed blinded SAT on fecal specimens and 16S rRNA tests on gastric specimens. Using nonlinear mixed models, SAT had a sensitivity of 85⋅1% (95%CI 76⋅54%, 93⋅6%), and specificity of 97⋅6% (95%CI 94⋅3, 100). Twelve individuals with dyspepsia need to be tested to correctly diagnose 10 with H. pylori infection using SAT. The SAT is a robust diagnostic test to improve the diagnosis of H. pylori infection in people with dyspepsia in resource-limited settings.

Abstract Background From May 2018 to September 2022, the Democratic Republic of Congo (DRC) experienced seven Ebola virus disease (EVD) outbreaks within its borders. During the 10th EVD outbreak (2018–2020), the largest experienced in the DRC and the second largest and most prolonged EVD outbreak recorded globally, a WHO risk assessment identified nine countries bordering the DRC as moderate to high risk from cross border importation. These countries implemented varying levels of Ebola virus disease preparedness interventions. This case study highlights the gains and shortfalls with the Ebola virus disease preparedness interventions within the various contexts of these countries against the background of a renewed and growing commitment for global epidemic preparedness highlighted during recent World Health Assembly events. Main text Several positive impacts from preparedness support to countries bordering the affected provinces in the DRC were identified, including development of sustained capacities which were leveraged upon to respond to the subsequent coronavirus disease 2019 (COVID-19) pandemic. Shortfalls such as lost opportunities for operationalizing cross-border regional preparedness collaboration and better integration of multidisciplinary perspectives, vertical approaches to response pillars such as surveillance, over dependence on external support and duplication of efforts especially in areas of capacity building were also identified. A recurrent theme that emerged from this case study is the propensity towards implementing short-term interventions during active Ebola virus disease outbreaks for preparedness rather than sustainable investment into strengthening systems for improved health security in alignment with IHR obligations, the Sustainable Development Goals and advocating global policy for addressing the larger structural determinants underscoring these outbreaks. Conclusions Despite several international frameworks established at the global level for emergency preparedness, a shortfall exists between global policy and practice in countries at high risk of cross border transmission from persistent Ebola virus disease outbreaks in the Democratic Republic of Congo. With renewed global health commitment for country emergency preparedness resulting from the COVID-19 pandemic and cumulating in a resolution for a pandemic preparedness treaty, the time to review and address these gaps and provide recommendations for more sustainable and integrative approaches to emergency preparedness towards achieving global health security is now.

PurposeThis study established the prevalence of physical and sexual victimization, associated factors and psychosocial consequences of victimization among 1,201 out-patients with severe mental illness at Butabika and Masaka hospitals in Uganda.MethodsParticipants completed structured, standardized and locally translated instruments. Physical and sexual victimization was assessed using the modified adverse life events module of the European Para-suicide Interview Schedule. We used logistic regression to determine the association between victimization, the associated factors and psychosocial consequences.ResultsThe prevalence of physical abuse was 34.1% and that of sexual victimization was 21.9%. The age group of > = 50 years (aOR 1.02;95% CI 0.62–1.66; p = 0.048) was more likely to have suffered physical victimization, while living in a rural area was protective against physical (aOR 0.59; 95% CI 0.46–0.76; p =

Abstract Background Globally, burn related deaths are disproportionately higher among children below 5 years of age compared to other age groups. Although rarely fatal, most burns in this group occur within homes specifically in kitchens. This study assessed the prevalence, risk factors and perceptions of caregivers regarding burns among children under 5 years in an urban slum in Kampala, Uganda. Methods The study used an analytic cross-sectional design with quantitative and qualitative techniques. Quantitative data were collected using a structured questionnaire and observational checklist, while qualitative data involved use of a key informant interview guide. A total of 426 children were involved in the study, while 6 key informants namely an adult mother, teenage mother, community health worker, health practitioner, father and local leader were interviewed. A modified Poisson regression model was used to determine the correlates of burn injuries, prevalence rate ratios and 95% confidence intervals, while thematic analysis was used for qualitative data. Results The prevalence of burns among under-fives was 32%, highest among those aged 24 to 35 months (39%), and least in those below 12 months (10%). Children with single parents (adj PR = 1.56 95% CI 1.07–2.29) and those from households in the middle and least poor wealth quintile (adj.PR = 1.72; 95% CI 1.02–2.89 and adj.PR = 1.77; 95% CI 1.02–3.05, respectively) were more likely to get burns compared to their counterparts in other quintiles. In households where flammables were safely stored, children were less likely to suffer from burn injuries (adj.PR = 0.61; 95% CI 0.44–0.83). Congestion, negligence of caregivers, and use of charcoal stoves/open cooking were the commonest determinants of burns. Although many caregivers offered first aid to burn patients, inadequate knowledge of proper care was noted. Crawling children were perceived as being at highest risk of burns. Conclusion The prevalence of burns among children under 5 years was high, with several household hazards identified. Health education, household modification and applicable public health law enforcement are recommended to reduce hazards and minimise burn risks among children.

IntroductionEvidence-based preventive strategies for cervical cancer in low-resource setting have been developed, but implementation is challenged, and uptake remains low. Women and girls experience social and economic barriers to attend screening and human papillomavirus (HPV) vaccination programs. Male support has been proven successful in uptake of other reproductive healthcare services. This qualitative study with focus groups aimed to understand the perspectives of males on cervical cancer screening and HPV vaccination in Western-Uganda This knowledge could be integrated into awareness activities to increase the attendance of cervical cancer screening and HPV vaccination programs.Materials and methodsFocus group discussions were conducted with men aged 25 to 60 years, who were married and/or had daughters, in Kagadi district, Mid-Western Uganda. All interviews were transcribed verbatim and thematically analyzed using an inductive approach.ResultsEleven focus group discussions were conducted with 67 men. Men were willing to support their wives for screening and their daughters for HPV vaccination. Misperceptions such as family planning and poor personal hygiene leading to cervical cancer, and misperception of the preventative aspect of screening and vaccination were common. Women with cervical cancer suffer from stigmatization and family problems due to loss of fertility, less marital sexual activity, domestic violence and decreased economic productivity.ConclusionsUgandan men were willing to support cervical cancer prevention for their wives and daughters after being informed about cervical cancer. Limited knowledge among men about the risk factors and causes of cervical cancer, and about the preventative aspect of HPV vaccination and screening and their respective target groups, can limit uptake of both services. Screening and vaccination programs should actively involve men in creating awareness to increase uptake and acceptance of prevention.

BackgroundRift Valley Fever virus (RVF) is a zoonotic virus in the Phenuiviridae family. RVF outbreaks can cause significant morbidity and mortality in humans and animals. Following the diagnosis of two RVF cases in March 2016 in southern Kabale district, Uganda, we conducted a knowledge, attitudes and practice (KAP) survey to identify knowledge gaps and at-risk behaviors related to RVF.Methodology/principal findingsA multidisciplinary team interviewed 657 community members, including abattoir workers, in and around Kabale District, Uganda. Most participants (90%) had knowledge of RVF and most (77%) cited radio as their primary information source. Greater proportions of farmers (68%), herdsmen (79%) and butchers (88%) thought they were at risk of contracting RVF compared to persons in other occupations (60%, p

Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming the most damaging and economically important disease of this crop. The identification and characterization of genes that regulate infection processes and pathogenicity in P. fijiensis will provide important knowledge for the development of disease-resistant cultivars. In many fungal plant pathogens, the Fus3 and Slt2 are reported to be essential for pathogenicity. Fus3 regulates filamentous-invasion pathways including the formation of infection structures, sporulation, virulence, and invasive and filamentous growth, whereas Slt2 is involved in the cell-wall integrity pathway, virulence, invasive growth, and colonization in host tissues. Here, we used RNAi-mediated gene silencing to investigate the role of the Slt2 and Fus3 homologs in P. fijiensis in pathogen invasiveness, growth and pathogenicity. The PfSlt2 and PfFus3 silenced P. fijiensis transformants showed significantly lower gene expression and reduced virulence, invasive growth, and lower biomass in infected leaf tissues of East African Highland Banana (EAHB). This study suggests that Slt2 and Fus3 MAPK signaling pathways play important roles in plant infection and pathogenic growth of fungal pathogens. The silencing of these vital fungal genes through host-induced gene silencing (HIG) could be an alternative strategy for developing transgenic banana and plantain resistant to BSD.

The onset of the pandemic revealed the health system inequities and inadequate preparedness, especially in the African continent. Over the past months, African countries have ensured optimum pandemic response. However, there is still a need to build further resilient health systems that enhance response and transition from the acute phase of the pandemic to the recovery interpandemic/preparedness phase. Guided by the lessons learnt in the response and plausible pandemic scenarios, the WHO Regional Office for Africa has envisioned a transition framework that will optimise the response and enhance preparedness for future public health emergencies. The framework encompasses maintaining and consolidating the current response capacity but with a view to learning and reshaping them by harnessing the power of science, data and digital technologies, and research innovations. In addition, the framework reorients the health system towards primary healthcare and integrates response into routine care based on best practices/health system interventions. These elements are significant in building a resilient health system capable of addressing more effectively and more effectively future public health crises, all while maintaining an optimal level of essential public health functions. The key elements of the framework are possible with countries following three principles: equity (the protection of all vulnerable populations with no one left behind), inclusiveness (full engagement, equal participation, leadership, decision-making and ownership of all stakeholders using a multisectoral and transdisciplinary, One Health approach), and coherence (to reduce the fragmentation, competition and duplication and promote logical, consistent programmes aligned with international instruments).

In this study, we evaluate the performance of a lab-scale filtration system for greywater treatment and reuse using sand and granular activated carbon as filter media. Using a laboratory, Physico-chemical and microbiological parameters are determined. The treatment efficiency comparison is made between lab-scale filtration systems that use gravel + sand and gravel + sand + GAC using pre-filtration and post-filtration mean values at different hydraulic retention times (HRT) and different filter columns. For both filter columns used, the treatment efficiency of the system increased with HRT at 12 h and 24 h and later on it decreased at 36 h. The pollution reduction was from 60.8% - 100% for selected parameters (pH, turbidity, BOD, COD, TC, and FC) in filter column B and from 47.2% - 100% for filter column A. Thus, filtration systems are efficient at improving hygiene, and water shortage at the university. Also, the results of the willingness to use the treated greywater (TGW) revealed that on the average, about 84.75%, 91.75%, and 100% of the respondents are willing to adopt the TGW for toilet flushing, pavement washing, and flower garden watering respectively.

Abstract Background Since the declaration of the 10th Ebola Virus Disease (EVD) outbreak in DRC on 1st Aug 2018, several neighboring countries have been developing and implementing preparedness efforts to prevent EVD cross-border transmission to enable timely detection, investigation, and response in the event of a confirmed EVD outbreak in the country. We describe Uganda’s experience in EVD preparedness. Results On 4 August 2018, the Uganda Ministry of Health (MoH) activated the Public Health Emergency Operations Centre (PHEOC) and the National Task Force (NTF) for public health emergencies to plan, guide, and coordinate EVD preparedness in the country. The NTF selected an Incident Management Team (IMT), constituting a National Rapid Response Team (NRRT) that supported activation of the District Task Forces (DTFs) and District Rapid Response Teams (DRRTs) that jointly assessed levels of preparedness in 30 designated high-risk districts representing category 1 (20 districts) and category 2 (10 districts). The MoH, with technical guidance from the World Health Organisation (WHO), led EVD preparedness activities and worked together with other ministries and partner organisations to enhance community-based surveillance systems, develop and disseminate risk communication messages, engage communities, reinforce EVD screening and infection prevention measures at Points of Entry (PoEs) and in high-risk health facilities, construct and equip EVD isolation and treatment units, and establish coordination and procurement mechanisms. Conclusion As of 31 May 2019, there was no confirmed case of EVD as Uganda has continued to make significant and verifiable progress in EVD preparedness. There is a need to sustain these efforts, not only in EVD preparedness but also across the entire spectrum of a multi-hazard framework. These efforts strengthen country capacity and compel the country to avail resources for preparedness and management of incidents at the source while effectively cutting costs of using a “fire-fighting” approach during public health emergencies.

Abstract Background HIV/AIDS continues to be a major global public health problem with Eastern and Southern Africa being the regions most affected. With increased access to effective antiretroviral therapy, HIV has become a chronic and manageable disease, bringing to the fore issues of quality of life including mental wellbeing. Despite this, the majority of HIV care providers in sub-Saharan Africa, including Uganda’s Ministry of Health, do not routinely provide mental health care including depression management. The purpose of this paper is to explore stakeholders’ perspectives on the feasibility and acceptability of integrating depression management into routine adult HIV care. The paper addresses a specific objective of the formative phase of the HIV + D study aimed at developing and evaluating a model for integrating depression management into routine HIV care in Uganda. Methods This was a qualitative study. Data were collected through in-depth interviews with 11 patients at enrollment and follow-up in the pilot phase, and exit interviews with 11 adherent patients (those who completed their psychotherapy sessions) and six non-adherent patients (those missing at least two sessions) at the end of the pilot phase. Key informant interviews were held with four clinicians, five supervisors and one mental health specialist, as were three focus group discussions with lay health workers. These were purposively sampled at four public health facilities in Mpigi District. Data were analysed thematically. Results Patients highlighted the benefits of treating depression in the context of HIV care, including improved adherence to antiretroviral therapy, overcoming sleeplessness and suicidal ideation, and regaining a sense of self-efficacy. Although clinicians and other stakeholders reported benefits of treating depression, they cited challenges in managing depression with HIV care, which were organisational (increased workload) and patient related (extended waiting time and perceptions of preferential treatment). Stakeholders generally shared perspectives on how best to integrate, including recommendations for organisational level interventions–training, harmonisation in scheduling appointments and structural changes–and patient level interventions to enhance knowledge about depression. Conclusions Integrating depression management into routine HIV care in Uganda is acceptable among key stakeholders, but the technical and operational feasibility of integration would require changes both at the organisational and patient levels.

Black Sigatoka disease, caused by Pseudocercospora fijiensis is a serious constraint to banana production worldwide. The disease continues to spread in new ecological niches and there is an urgent need to develop strategies for its control. The high osmolarity glycerol (HOG) pathway in Saccharomyces cerevisiae is well known to respond to changes in external osmolarity. HOG pathway activation leads to phosphorylation, activation and nuclear transduction of the HOG1 mitogen-activated protein kinases (MAPKs). The activated HOG1 triggers several responses to osmotic stress, including up or down regulation of different genes, regulation of protein translation, adjustments to cell cycle progression and synthesis of osmolyte glycerol. This study investigated the role of the MAPK-encoding PfHog1 gene on osmotic stress adaptation and virulence of P. fijiensis. RNA interference-mediated gene silencing of PfHog1 significantly suppressed growth of P. fijiensis on potato dextrose agar media supplemented with 1 M NaCl, indicating that PfHog1 regulates osmotic stress. In addition, virulence of the PfHog1-silenced mutants of P. fijiensis on banana was significantly reduced, as observed from the low rates of necrosis and disease development on the infected leaves. Staining with lacto phenol cotton blue further confirmed the impaired mycelial growth of the PfHog1 in the infected leaf tissues, which was further confirmed with quantification of the fungal biomass using absolute- quantitative PCR. Collectively, these findings demonstrate that PfHog1 plays a critical role in osmotic stress regulation and virulence of P. fijiensis on its host banana. Thus, PfHog1 could be an interesting target for the control of black Sigatoka disease in banana.

Abstract Background An estimated 8–30 % of people living with HIV (PLWH) have depressive disorders (DD) in sub-Saharan Africa. Of these, the majority are untreated in most of HIV care services. There is evidence from low- and middle- income countries of the effectiveness of both psychological treatments and antidepressant medication for the treatment of DD among PLWH, but no evidence on how these can be integrated into routine HIV care. This protocol describes a cluster-randomised trial to evaluate the effectiveness and cost-effectiveness of the HIV + D model for the integration of a collaborative stepped care intervention for DD into routine HIV care, which we have developed and piloted in Uganda. Methods Forty public health care facilities that provide HIV care in Kalungu, Masaka and Wakiso Districts will be randomly selected to participate in the trial. Each facility will recruit 10–30 eligible PLWH with DD and the total sample size will be 1200. The clusters will be randomised 1:1 to receive Enhanced Usual Care alone (EUC, i.e. HIV clinicians trained in Mental Health Gap Action Programme including guidelines on when and where to refer patients for psychiatric care) or EUC plus HIV + D (psychoeducation, Behavioural Activation, antidepressant medication and referral to a supervising mental health worker, delivered in a collaborative care stepwise approach). Eligibility criteria are PLWH attending the clinic, aged ≥ 18 years who screen positive on a depression screening questionnaire (Patient Health Questionnaire, PHQ-9 ≥ 10). The primary outcome is the mean depressive disorder symptom severity scores (assessed using the PHQ-9) at 3 months’ post-randomisation, with secondary mental health, disability, HIV and economic outcomes measured at 3 and 12 months. The cost-effectiveness of EUC with HIV + D will be assessed from both the health system and the societal perspectives by collecting health system, patient and productivity costs and mean DD severity scores at 3 months, additional to health and non-health related quality of life measures (EQ-5D-5 L and OxCAP-MH). Discussion The study findings will inform policy makers and practitioners on the cost-effectiveness of a stepped care approach to integrate depression management in routine care for PLWH in low-resource settings.

On April 20, 2018, the Kween District Health Office in Kween District, Uganda reported 7 suspected cases of human anthrax. A team from the Uganda Ministry of Health and partners investigated and identified 49 cases, 3 confirmed and 46 suspected; no deaths were reported. Multiple exposures from handling the carcass of a cow that had died suddenly were significantly associated with cutaneous anthrax, whereas eating meat from that cow was associated with gastrointestinal anthrax. Eating undercooked meat was significantly associated with gastrointestinal anthrax, but boiling the meat for >60 minutes was protective. We recommended providing postexposure antimicrobial prophylaxis for all exposed persons, vaccinating healthy livestock in the area, educating farmers to safely dispose of animal carcasses, and avoiding handling or eating meat from livestock that died of unknown causes.

Abstract Background On 23 February 2018, the Uganda Ministry of Health (MOH) declared a cholera outbreak affecting more than 60 persons in Kyangwali Refugee Settlement, Hoima District, bordering the Democratic Republic of Congo (DRC). We investigated to determine the outbreak scope and risk factors for transmission, and recommend evidence-based control measures. Methods We defined a suspected case as sudden onset of watery diarrhoea in any person aged ≥ 2 years in Hoima District, 1 February–9 May 2018. A confirmed case was a suspected case with Vibrio cholerae cultured from a stool sample. We found cases by active community search and record reviews at Cholera Treatment Centres. We calculated case-fatality rates (CFR) and attack rates (AR) by sub-county and nationality. In a case-control study, we compared exposure factors among case- and control-households. We estimated the association between the exposures and outcome using Mantel-Haenszel method. We conducted an environmental assessment in the refugee settlement, including testing samples of stream water, tank water, and spring water for presence of fecal coliforms. We tested suspected cholera cases using cholera rapid diagnostic test (RDT) kits followed by culture for confirmation. Results We identified 2122 case-patients and 44 deaths (CFR = 2.1%). Case-patients originating from Demographic Republic of Congo were the most affected (AR = 15/1000). The overall attack rate in Hoima District was 3.2/1000, with Kyangwali sub-county being the most affected (AR = 13/1000). The outbreak lasted 4 months, which was a multiple point-source. Environmental assessment showed that a stream separating two villages in Kyangwali Refugee Settlement was a site of open defecation for refugees. Among three water sources tested, only stream water was feacally-contaminated, yielding > 100 CFU/100 ml. Of 130 stool samples tested, 124 (95%) yielded V. cholerae by culture. Stream water was most strongly associated with illness (odds ratio [OR] = 14.2, 95% CI: 1.5–133), although tank water also appeared to be independently associated with illness (OR = 11.6, 95% CI: 1.4–94). Persons who drank tank and stream water had a 17-fold higher odds of illness compared with persons who drank from other sources (OR = 17.3, 95% CI: 2.2–137). Conclusions Our investigation demonstrated that this was a prolonged cholera outbreak that affected four sub-counties and two divisions in Hoima District, and was associated with drinking of contaminated stream water. In addition, tank water also appears to be unsafe. We recommended boiling drinking water, increasing latrine coverage, and provision of safe water by the District and entire High Commission for refugees.

Uganda established a domestic Viral Hemorrhagic Fever (VHF) testing capacity in 2010 in response to the increasing occurrence of filovirus outbreaks. In July 2018, the neighboring Democratic Republic of Congo (DRC) experienced its 10th Ebola Virus Disease (EVD) outbreak and for the duration of the outbreak, the Ugandan Ministry of Health (MOH) initiated a national EVD preparedness stance. Almost one year later, on 10th June 2019, three family members who had contracted EVD in the DRC crossed into Uganda to seek medical treatment. Samples were collected from all the suspected cases using internationally established biosafety protocols and submitted for VHF diagnostic testing at Uganda Virus Research Institute. All samples were initially tested by RT-PCR for ebolaviruses, marburgviruses, Rift Valley fever (RVF) virus and Crimean-Congo hemorrhagic fever (CCHF) virus. Four people were identified as being positive for Zaire ebolavirus, marking the first report of Zaire ebolavirus in Uganda. In-country Next Generation Sequencing (NGS) and phylogenetic analysis was performed for the first time in Uganda, confirming the outbreak as imported from DRC at two different time point from different clades. This rapid response by the MoH, UVRI and partners led to the control of the outbreak and prevention of secondary virus transmission.
