Abstract Introduction Salmonella Typhi infections cause significant morbidity and mortality worldwide, especially in developing countries including Ethiopia. This study aimed to determine the prevalence of Salmonella Typhi, its associated factors and antibiotic susceptibility profile among suspected typhoid patients. Methods A cross-sectional study was conducted on 270 typhoid fever suspected patients at Hawassa University Comprehensive Specialized Hospital from June 2022 to September 2022. Data were collected using questionnaires by face-to-face interview. Stool samples for microbiological culture, blood samples for S. Typhi IgM/Entero-check WB rapid test and isolates for antimicrobial susceptibility tests were used through standard procedures and according to the reagents manufactures’ instructions. Hygiene implementation of patients was also assessed using interview. Sociodemographic and clinical characteristics of the patient’s were considered. Descriptive statistics were used to summarize the data, and logistic regression model analysis was performed to assess associations between S. Typhi infection and the associated sociodemographic and clinical factors. Results The prevalence of S. Typhi IgM/Entero-check WB rapid test and stool culture results were 3.3%; (95% CI: 1.5–5.6) and 3.7%; (95% CI: 1.9–6.3) respectively. Not washing hands after latrine [AOR = 0.85, 95% CI (0.15–4.79), p = 0.05] is not significant but, not washing hands before meal [AOR = 0.053, 95% CI (0.08–0.36), p = 0.03], eating raw vegetables [AOR = 0.024, 95% CI (0.001–0.48), p = 0.015] and drinking water from a stream [AOR = 0.12, 95% CI (0.19–0.70), p = 0.001] were significantly associated with S. Typhi infection, but in terms of AOR, all are preventive. Susceptibility of isolates was 9/10 (90%), 8/10 (80%), and 8/10 (80%) to ciprofloxacin, ceftriaxone, and chloramphenicol, respectively. The majorities 100% and 80% of the isolates were resistant to ampicillin and cotrimoxazole, respectively. About 40% of the isolates were MDR. Conclusion The prevalence of Salmonella Typhi with MDR has been observed. Therefore, health programmers and stakeholders should make efforts to improve the habit of sanitation, strengthen the capacity of laboratory diagnostic methods and increase awareness of the misprescription and misuse of antibiotics to reduce the impact of MDR bacteria.

Abstract Introduction Proper diagnosis of tuberculosis (TB) lymphadenitis is critical for its treatment and prevention. Fine needle aspirate cytology (FNAC) is the mainstay method for the diagnosis of TB lymphadenitis in Ethiopia; however, the performance of FNAC has not been evaluated in the Eastern Region of Ethiopia. This study aimed to evaluate the performance of FNAC and Ziehl-Neelsen (ZN) staining compared with that of GeneXpert for the diagnosis of TB lymphadenitis. Methods Fine needle aspiration (FNA) specimens collected from 291 patients suspected of having TB lymphadenitis were examined using FNAC, ZN, and GeneXpert to diagnose TB lymphadenitis. Gene-Xpert was considered the reference standard method for comparison. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and kappa coefficient were determined using SPSS version 25. Results The sensitivity, specificity, PPV, and NPV of ZN for diagnosing TB lymphadenitis were 73.2%, 97.4%, 96.2%, and 80.1% respectively. There was poor agreement between ZN and GeneXpert (Kappa=-0.253). The sensitivity, specificity, PPV, and NPV of FNAC were 83.3%, 94.8%, 93.5%, and 86.3% respectively. There was moderate agreement between the FNAC and GeneXpert (Kappa = 0.785). Conclusion The fine needle aspiration cytology (FNAC) is a more sensitive test for the diagnosis of TB lymphadenitis than ZN. The FNAC showed a moderate agreement with the GeneXpert assay. This study recommends the FNA GeneXpert MTB/RIF test in preference to FNAC for the diagnosis of TB lymphadenitis to avoid a missed diagnosis of smear-negative TB lymphadenitis.

BackgroundEight years into the Sustainable Development Goal period, Ethiopia is not on track to achieve good hygiene practices among school children. Ensuring good hygiene practices among primary school children to prevent the spread of communicable diseases remains a challenge in most primary schools in Ethiopia. Therefore, the aim of this study was to identify factors associated with hygiene practices among primary school children in southern Ethiopia.MethodsA school-based cross-sectional study was conducted from June 3 to July 28, 2022, in five primary schools. The simple random sampling technique was used to select the school. Subsequently, 640 students were selected from the proportionally allocated sample size. Pretested semi-structured interviewer-administered questionnaires and observational checklists were utilized to collect data. The data was then entered into EpiData version 4.6 and analyzed using SPSS version 25. Variables with a p ≤ 0.25 at bivariate analysis were used to develop a multivariable logistic model to identify factors associated with hygiene practices. P < 0.05 with a 95% confidence interval was considered statistically significant.ResultsThe magnitude of overall good hygiene practices was 29.2% (95% CI: 25.81–32.59). Urban residence (AOR = 3.4, 95% CI 2.1–5.55), knowledge of handwashing (AOR = 4.5, 95% CI 2.8–7.36), being a member of a hygiene and sanitation club (AOR = 3.7, 95% CI 2.4–6.86), and experience of visiting a model school (AOR = 3.1, 95% CI 2.1–5.55) were found to be significantly associated with hygiene practices.ConclusionThe overall level of good hygiene practices in Kedida district was low. Therefore, it is essential to enhance health education on handwashing, establish sanitation and hygiene clubs, and conduct visits to district model elementary schools.

IntroductionEthiopia has one of the highest maternal death rates in the world, with 412 deaths for every 100,000 live births. A qualified healthcare professional's care during pregnancy, delivery, and the postnatal period is crucial to saving the lives of the mother and her child. The continuum of maternity health services in Ethiopia is still shallow, despite efforts to increase the use of these services. This study's goal was to evaluate the magnitude and factors influencing the entire continuum of care for maternal health services in Chiro City in 2024.MethodsA community-based cross-sectional study was conducted from 15 January to 15 February 2024, among mothers who gave birth in the last year preceding the data collection period in Chiro City, Eastern Ethiopia. Data were collected through face-to-face interviews using a structured questionnaire. Multivariable logistic regression analysis was done to identify determinants of the complete continuum of care. A P-value of

IntroductionBreast cancer continues to be the most common malignancy and the leading cause of cancer-related deaths in Ethiopia. The poor prognosis and high mortality rate of breast cancer patients in the country are largely caused by late-stage diagnosis. Hence, understanding the epidemiology of late-stage diagnosis is essential to address this important problem. However, previous reports in Ethiopia indicated inconsistent findings. Therefore, this literature review was conducted to generate dependable evidence by summarizing the prevalence and determinants of late-stage diagnosis among breast cancer patients in Ethiopia.MethodsPertinent articles were retrieved by systematically searching on major electronic databases and gray literature. Data were extracted into an Excel spreadsheet and analyzed using the STATA 17 statistical software. The pooled estimates were summarized using the random effect meta-analysis model. Heterogeneity and small study effect were evaluated using the I2 statistics and Egger's regression test in conjunction with the funnel plot, respectively. Meta-regression, sub-group analysis, and sensitivity analysis were also employed. Protocol registration number: CRD42024496237.ResultsThe pooled prevalence of late-stage diagnosis after combining reports of 24 studies with 8,677 participants was 65.85 (95% CI: 58.38, 73.32). Residence (adjusted OR: 1.92; 95% CI: 1.45, 2.53), patient delay at their first presentation (adjusted OR: 2.65; 95% CI: 1.56, 4.49), traditional medicine use (adjusted OR: 2.54; 95% CI: 1.89, 3.41), and breast self-examination practice (adjusted OR: 0.28; 95% CI: 0.09, 0.88) were significant determinants of late-stage diagnosis.ConclusionTwo-thirds of breast cancer patients in Ethiopia were diagnosed at an advanced stage. Residence, delay in the first presentation, traditional medicine use, and breast self-examination practice were significantly associated with late-stage diagnosis. Public education about breast cancer and its early detection techniques is crucial to reduce mortality and improve the survival of patients. Besides, improving access to cancer screening services is useful to tackle the disease at its curable stages.

BackgroundWith the persisting low vaccination intake, particularly in children of low-and middle-income countries (LMICs), seroepidemiological studies are urgently needed to guide and tailor COVID-19 pandemic response efforts in schools and to put mitigation strategies in place for a future post-pandemic resurgence. However, there is limited data on SARS-CoV-2 infection-induced and vaccine-induced humoral immunity in schoolchildren in LMICs, including Ethiopia.MethodsAs the spike receptor binding domain (RBD) is the major target for neutralization antibodies and useful to predict the correlates of protection, we used an in-house anti-RBD IgG ELISA to assess and compare infection-induced antibody response at two-time points and BNT162b2 (BNT) vaccine-induced antibody response at a one-time point in schoolchildren in Hawassa, Ethiopia. In addition, we measured and compared the levels of binding IgA antibodies to spike RBD of SARS-CoV-2 Wild type, Delta, and Omicron variants in a small subset of unvaccinated and BNT-vaccinated schoolchildren.ResultsWhen we compare SARS-CoV-2 infection-induced seroprevalences among unvaccinated school children (7-19 years) at the two blood sampling points with a 5-month interval, we observed an over 10% increase, from 51.8% (219/419) in the first week of December 2021 (post-Delta wave) to 67.4% (60/89) by the end of May 2022 (post-Omicron wave). Additionally, we found a significant correlation (p = 0.001) between anti-RBD IgG seropositivity and a history of having COVID-19-like symptoms. Compared to the levels of SARS-CoV-2 infection-induced anti-RBD IgG antibodies before vaccination, higher levels of BNT vaccine-induced anti-RBD IgG antibodies were observed even in SARS-CoV-2 infection-naïve schoolchildren of all age groups (p = 0.0001). Importantly, one dose of the BNT vaccine was shown to be adequate to elicit a strong antibody response in schoolchildren with pre-existing anti-RBD IgG antibodies comparable to that of SARS-CoV-2 infection-naive schoolchildren receiving two doses of BNT vaccine, suggesting a single dose administration of the BNT vaccine could be considered for schoolchildren who had prior SARS-CoV-2 infection when a shortage of vaccine supply is a limiting factor to administer two doses irrespective of their serostatus. Despite the small sample size of study participants, the BNT vaccine is shown to be immunogenic and safe for schoolchildren. Irrespective of schoolchildren’s vaccination status, we observed a similar pattern of significantly higher levels of IgA antibodies to Delta-RBD than to Omicron-RBD (p < 0.001) in a randomly selected subset of schoolchildren, yet comparable to Wuhan-RBD, suggesting these schoolchildren were more likely to have had SARS-CoV-2 infection with Delta variant. Additionally, we noted a broader IgA antibody reactivity to SARS-CoV-2 variants in vaccinated schoolchildren with prior SARS-CoV-2 infection, supporting the superiority of hybrid immunity.ConclusionOur serological data indicate a significant increase in SARS-CoV-2 seroprevalence in children at a post-Omicron five-month follow-up compared to a post-Delta enrolment. Despite the small sample size of study participants, the BNT vaccine is shown to be immunogenic and safe for schoolchildren. Hybrid immunity would likely provide a broader humoral immunity against Wuhan strain, Delta, and Omicron variants than natural infection or vaccination alone does. However, future longitudinal cohort studies in SARS-CoV-2-naïve and COVID-19-recovered schoolchildren receiving the BNT vaccine are needed for a better understanding of the kinetics, breadth, and durability of BNT vaccine-induced multivariant-cross reactive immunity.
