Disclosure of diagnosis by parents and caregivers to children infected with HIV in Hawassa, southern Ethiopia: a multicentre, cross-sectional study.

BACKGROUND: In recent years, the life expectancy of human immunodeficiency virus (HIV)-infected children has increased with the availability of highly active antiretroviral therapy (ART). Regardless of the clinical recommendations encouraging HIV status disclosure, the practice of caregiver disclosure is frequently challenging due to many constraints associated with caregivers and healthcare personnel. As studies suggest, disclosure of the HIV-positive status of children is low, particularly in sub-Saharan Africa, where the majority of infected children reside. Thus the primary objective of this study was to evaluate the prevalence of HIV-positive status disclosure to infected children and the pertinent factors associated with caregivers of these children. Moreover, unlike previous studies conducted in Ethiopia, this study included children residing in orphanages. METHODS: We assessed HIV-positive status disclosure and associated factors among infected children in Hawassa, southern Ethiopia, from 25 May to 20 July 2021. A facility-based cross-sectional study was conducted in six public health facilities that provide HIV treatment and care. Data were collected from 355 randomly selected caregivers using interviewer-administered questionnaires and record reviews. Binary and multiple logistic regression was used to explore the association between independent variables and the outcome. The adjusted odds ratio (aOR) with 95% confidence interval (CI) was computed to determine the strength of the association and a p-value <0.05 was considered statistically significant. RESULTS: Of the 355 children, 132 (37.2%) were informed about their HIV-positive status. Being of young age (≤12 y) (aOR 0.52 [95% CI 0.28 to 0.98]), having caregivers who were not familiar with anyone who disclosed children's HIV status (aOR 0.28 [95% CI 0.16 to 0.49]), children with a family that had a primary education (aOR 0.46 [95% CI 0.23 to 0.89]) and being a child who has taken ART for <5 y (aOR 0.47 [95% CI 0.28 to 0.80]) had a significant association with non-disclosure of HIV-positive status to infected children. CONCLUSIONS: The findings show that disclosure of HIV-positive status to infected children is low. This suggests the need to provide support and education to caregivers, facilitate experience-sharing sessions between caregivers who disclosed the HIV status to infected children and implement age-specific disclosure interventions for young children. In addition, it is important to provide support and counselling to the children when their HIV status is disclosed.

Magnitude, associated factors, and antimicrobial susceptibility pattern of bacterial isolates among adult dental caries patients attending Hiwot Fana comprehensive specialized university hospital, Harar, Eastern Ethiopia.

BACKGROUND: Dental caries is defined as a dynamic diet microbial disease of teeth, which results in localized dissolution and destruction of the mineralized tissues of the teeth. Dental caries develops when there is a susceptible tooth exposed to pathogenic bacteria in the presence of substrate. Under these conditions, the bacteria metabolize substrate to form acid, which decalcifies teeth. Dental caries is among the top oral health problem in both developing and developed nations affecting around 20-50% of the population globally. OBJECTIVE: This study was conducted to assess the magnitude, associated factors, and antimicrobial susceptibility pattern of bacterial isolates among adult dental caries patients visiting Hiwot Fana specialized university hospital dental clinic from April 23 to-June 23, 2021. METHODS: An institutional-based cross-sectional study was conducted among 290 study participants. Convenient sampling techniques were used to select the study participants. Data was entered into Epi-info version 7.2.4.0 and exported to Statistical Package for the Social Sciences version 20 for analysis. The result was explained by using summary measures of texts, tables, and graphs after analysis by using bivariate and multivariate logistic regression. Statistical significance was defined at a p-value of less than 0.05. RESULT: The overall magnitude of bacteria among dental caries patients was 68.3%. S mutans 74(37.4%) and Lactobacillus spp 58(29.3%) were the most predominant isolated bacteria. Lack of teeth brushing (AOR: 2.8, 95% CI:1.6, 4.6), the habit of chewing khat always (AOR:4.8, 95%CI:2.10,8.80), the habit of chewing khat sometimes (AOR: 3.8: 95% CI: 2.520,9.48) and consumption of soft drinks (AOR: 1.9, 95% CI:1.2,3.1) were significantly associated with bacterial dental caries. Almost, all bacterial isolates were susceptible to ceftriaxone and ciprofloxacin compared to Amoxicillin, Azithromycin, chloramphenicol, clindamycin, doxycycline, erythromycin, gentamycin, penicillin, tetracycline, vancomycin and tobramycin. CONCLUSION: Teeth brushing habit, consumption of soft drink and a habit of chewing khat affects dental health and they are associated with bacterial dental caries. Harari regional health bureau better to focus by giving health education to the community about dental caries based on identified associated factors with dental caries.

Seasonal Variability Influence on the Prevalence of Diarrhoea among Under-Five-Year-old Children in Kersa District, Eastern Ethiopia: A Community-Based Longitudinal Study.

Background: The health effects of climate change have been found to be a global concern for the last 2 centuries. However, the effect of climate variability on diarrhoea among under-five-year-old children is perhaps undocumented or otherwise unknown. The aim of the present study was to determine the effect of climate variability on diarrhoea among children under 5 years of age. Methods: A community-based longitudinal study was conducted over 8 repeated visits from June 2016 to May 2018 at the Kersa Demographic Surveillance and Health Research Center. A total of 500 randomly selected households and their 48 improved water sources were included in the survey from 3 agro-ecological zones, the rural and urban areas of the study area. Data was collected on household characteristics, diarrhoea, WASH practices, water quality and quantity in households, and improved water sources. A structured pre-tested questionnaire, an observational check list and laboratory tests were used for data collection. The data was entered into Epi Data Version 3.01 and transferred to Stata Version 12 for analysis. Multilevel mixed-effect Poisson regression was used to determine the relationship between predictors and outcome variables. A P-value of less than .05 was the cut-off point for statistically significant. Results: The prevalence of diarrhoea in 2 weeks among children under 5 years of age was 17.2% (95% CI: 15.8-19.71). Rainfall, E. coli contamination of drinking water at the source and in the home, 20 L of water consumption per capita per day, sharing water sources with animals and home water treatment by residents of the mid- and lowlands were all predictors of diarrhoea. The space-time scan statistic confirmed that child diarrhoea had random variation in both space and time. Conclusion: Climate variability has influenced the prevalence of diarrhoea among under-five-year-old children. Climate-resilient measures should be taken to reduce the burden of diarrhoea in the community.

COVID-19 Testing Experience in a Resource-Limited Setting: The Use of Existing Facilities in Public Health Emergency Management.

Introduction: Coronavirus disease 2019 (COVID-19) is a public health emergency with little testing and treatment experiences at its occurrence. Diagnostic and treatment rapidly changed in the world including Ethiopia. Haramaya University has strived to change its diagnostic capacity using existing facilities in response to the national call to the pandemic.

The pandemic has been an opportunity in harnessing existing resource for the benefit of the public during such times of dire needs to provide critical public health laboratory interventions.

Analysis of salivary level Lactobacillus spp. and associated factors as determinants of dental caries amongst primary school children in Harar town, eastern Ethiopia.

BACKGROUND: Lactobacillus spp. play a major role in the development of dental caries. Although effective methods are known for the prevention and management of dental caries, its prevalence of dental caries is increasing amongst school-age children in Ethiopia. Hence, this study is aimed to determine the association of salivary Lactobacillus spp. level and oral health factors as determinants of dental caries amongst primary school children in Harar town, Eastern Ethiopia. METHODS: A cross-sectional study was conducted amongst primary school children (n = 407) using a questionnaire survey, clinical DMFT (decayed, missing, filled tooth number) examination and enumeration of salivary level Lactobacillus spp. Data were analyzed by SPSS (Statistical Package for Social Science software- version 25.0). The odds ratio was used to determine the predictors of the outcome. The data were expressed as mean ± SD. Statistical significance was defined as a p-value of less than 0.05. RESULTS: The prevalence of dental caries was found to be 36.9% amongst primary school children. The mean DMFT value of the participants was 0.95 ± 1.57. The dental decay component was the primary observation that accounted for 84.6% of the DMFT. Almost, 67% of the saliva culture revealed a significant amount of Lactobacillus spp. COUNT: The mean bacterial count was found to be 14.92 × 105 ± 22.92 × 105. Among various parameters analysed for association with dental caries, a number of them show positive associtation, incluing reduction in academic scores in the prevous academic year (p = 0.034), grade levels of school children 1-4 (p = 0.041), sweet food consumption habit (p = 0.003), absence of daily teeth cleaning habit (p = 0.002), absence of toothpaste use (p = 0.001), dental ache history (p = < 0.001), significant microbial load of salivary Lactobacillus spp. (p = < 0.001), acidic (p = 0.028) and basic salivary pH (p = 0.025). CONCLUSION: A significant salivary Lactobacillus count associated with lower grade level, sweet diet, and poor oral hygiene were found to be the determinant factors for dental caries. Thus, dissemination of oral health information is obligatory to prevent dental caries amongst primary school children in the study area.

Non-critical healthcare tools as a potential source of healthcare-acquired bacterial infections in eastern Ethiopia: A hospital-based cross-sectional study.

BACKGROUND: Outbreaks of healthcare-acquired infections have been linked to contaminated medical devices such as electronic thermometers, sphygmomanometers, stethoscopes, latex gloves, masks, neckties, white coats and other. OBJECTIVE: The aim of this study was to assess non-critical healthcare tools as a potential source of healthcare-acquired bacterial infections and associated factors in public health hospitals of Harar, eastern Ethiopia from March 2016 to February 2017. METHODS: A hospital-based cross-sectional study was conducted on 212 non-critical healthcare tools owned by different health professionals. The data were collected from each owner using self-administered questionnaire. Swab specimens were collected from 187 stethoscopes and 25 sphygmomanometers using sterile cotton tips. Bacterial investigation and antimicrobial susceptibility tests were performed using standard culture tests. The data were double entered into EPI-Data version 3.1 and exported into the Statistical Package for Social Sciences version 16 for analysis. RESULT: The overall prevalence of non-critical healthcare tool contamination was 53.8%. A total of 137 bacterial strains were isolated. Staphylococcus aureus was the most frequent isolate (35%). Resistance to two or more different classes of antimicrobial was found to be 19.3%. The proportion of stethoscopes or sphygmomanometers contamination owned by the health professionals who were not cleaned regularly before and after examining each patient was found to be high (77%). The majority of non-critical healthcare tools used by health professionals working in the intensive care unit were contaminated (75%) followed by medical wards (73.5%). CONCLUSION: This study confirmed that the majority of the stethoscopes and sphygmomanometers were contaminated with pathogenic bacteria known to be associated with healthcare-acquired infections. Most of the healthcare workers did not practice stethoscope and sphygmomanometers disinfection. Strict and careful decontamination of stethoscopes and sphygmomanometers need to be in place before use.
