High prevalence of active trachoma and associated factors among school-aged children in Southwest Ethiopia.

BACKGROUND: Active trachoma is a highly contagious ongoing stage of trachoma that predominantly occurs during childhood in an endemic area. This study assessed the prevalence and factors associated with active trachoma among school-aged children. METHODOLOGY/PRINCIPAL FINDINGS: A community-based analytical cross-sectional study was done from March 1st to June 30th, 2021, in Southwest Ethiopia's people's regional state. A total of 1292 school-aged children were surveyed. The quantitative data were collected using a pre-tested, structured interview-based questionnaire and observation check list. The World health organization (WHO) simplified trachoma grading system was used to assess stages of trachoma. In this study, the prevalence of active trachoma was 570(44.1%), 95% CI (41.4, 46.9). Also, age group 6-10; being female; flies at household (HH), flies on child's face, improved water source, improved sanitation, presence of ocular discharge, presence of nasal discharge, and unclean faces of the child were significantly associated with active trachoma. CONCLUSIONS/SIGNIFICANCE: The very high prevalence of active trachoma in the study area is significantly associated with; age group 6-10, female gender, presence of flies in household and on child's face, presence of ocular and nasal discharge, unclean faces, improved water source, improved sanitation in the household. Thus, environmental sanitation and facial cleans trachoma elimination strategy should be intensified in the study area.

SARS-CoV-2 Infections, Clinical Characteristics, and Related Risk Factors: The First 8 Months Surveillance Study Conducted in Southwest Ethiopia.

Coronavirus disease 2019 (COVID-19) is caused by a severe acute respiratory syndrome coronavirus (SARS-CoV-2) and became pandemic after emerging in Wuhan, China, in December 2019. We aimed to investigate the prevalence, clinical characteristics, and risk factors for SARS-CoV-2 infections in districts of southwest Ethiopia. A study was conducted on COVID-19 surveillance data in the diagnostic center of the southwest district of Ethiopia from July 1, 2020, to February 30, 2021. A total of 10 618 nasopharyngeal specimens were tested for SARS-COV-2 using the detection of unique sequences of virus RNA by reverse transcriptase PCR. Data were entered into Epidata version 3.1 and analyzed using SPSS version 25. Logistic regression was used to determine the relationship between COVID-19 and risk factors, with a significance level of P = 0.05. A total of 10 618 individuals were tested for SARS-CoV-2. Of these, 419 (3.9%) patients tested positive for SARS-CoV-2. Among a total of 419 patients who tested positive for SARS-CoV-2, 80.2% were asymptomatic, 264 (63.0%) were males, and 233 (55.6%) were aged 19 to 35 years. Comorbidity was present in 37 (8.8%). The risk of getting SARS-CoV-2 infections was increased with male sex (AOR = 1.248; 95% CI: 1.007, 1.547), health workers (AOR = 3.187; 95% CI: 1.960, 5.182), prisoners (AOR = 2.118; 95% CI: 1.104, 4.062), and comorbid conditions (AOR = 2.972; 95% CI: 1.649, 5.358), such as diabetes (AOR = 4.765; 95% CI: 1.977-11.485) and other respiratory problems (AOR = 3.267; 95% CI: 1.146-9.317). Despite the fact that overall laboratories confirmed prevalence of SARS-CoV-2 infections in the study area was low and dynamic, it was spread to all zones of the study area. This highlights the importance of implementing the most effective public health strategies to prevent the further spread and reduce the burden of SARS-CoV-2 infections.

Utilization of skilled birth attendant at birth and associated factors among women who gave birth in the last 24 months preceding the survey in Gura Dhamole Woreda, Bale zone, southeast Ethiopia.

BACKGROUND: Maternal morbidity and mortality continued to be major issues in many countries. Globally a total of 10.7 million women have died between 1990 and 2015 due to maternal causes where sub-Saharan Africa alone accounts for 66% of maternal death. Since most maternal deaths are avoidable; skilled attendance during pregnancy, childbirth, and the postpartum is among the most critical interventions for improving maternal and neonatal survival. The study aimed to assess the magnitude and associated factors of utilization of skilled birth attendant at birth among women who gave birth in the last 24 months preceding the study in Gura Dhamole Woreda, Bale Zone Southeast Ethiopia, 2017. METHODS: Community based cross-sectional study was implemented from March 25 to April 24, 2017 in Gura Dhamole Woreda on total of 402 study subjects who were selected by Multi-stage sampling technique. The data were collected using pre-tested structured questionnaire and data was coded, entered, cleaned and analyzed using Statistical Package for Social Service (SPSS) Version 20. Odds ratio with 95% Confidence Interval (CI) was used to assess associations the dependent and independent variables. Logistic regression model was employed to identify independent predictors and variables were declared statistically significant at P value < 0.05. RESULT: In this study only 29.2% of women were assisted by Skilled Birth Attendance (SBA) during their child birth. Place of residence, mother education, travel time, joint decision on the place of delivery, ANC visit frequency, birth preparedness and complication readiness status, knowledge on obstetric danger signs after delivery and knowledge of presence of maternity waiting homes were significantly associated with SBA utilization. CONCLUSION: Skilled birth attendant utilization in the study area was low. Strategies that improve attendance of antenatal care utilization and attention to birth preparedness and complication readiness and counseling on danger signs are recommended.

Prevalence and associated factors of treatment failure among HIV/AIDS patients on HAART attending University of Gondar Referral Hospital Northwest Ethiopia.

BACKGROUND: The initiation of highly active antiretroviral therapy (HAART) plays a significant role in the clinical management of HIV infected people by preventing morbidity and mortality. This benefit becomes, the most terrible when treatment failure develops. Thus, this research aims to assess the prevalence and associated factors of treatment failure among HIV/AIDS patients on HAART attending University of Gondar Referral Hospital Northwest Ethiopia. RESULTS: Patients on ART with a minimum of 6 months and up to 12 years of treatment were being enrolled. The prevalence of treatment failure, immunological failure and virological failure among people living with HIV/AIDS attending University of Gondar referral hospital were 20.3, 13.2, and 14.7%, respectively. Patients who had no formal education (Adjusted odds ratio (AOR): 3.8; 95% CI, 1.05-13.77), primary level education (AOR: 4.2; 95% CI, 1.16-15.01) and duration on ART < 6 years (AOR: 2.1; 95%CI, 1.12-3.81) were a significant risk factor. However, initial adult regimen D4T +  3TC+ EFV (AOR: 0.025; 95% CI, 0.002-0.36), AZT +3TC + NVP (AOR: 0.07; 95% CI, 0.01-0.71), AZT +  3TC + EFV (AOR: 0.046; 95% CI, 0.004-0.57) andTDF+3TC + EFV (AOR: 0.04; 95% CI, 0.004-0.46) were significantly protective for treatment failure. CONCLUSIONS: Timely and early identification of associated factors and monitoring antiretroviral therapy treatment failure should be done to enhance the benefit and to prevent further complication of the patients. It is preferable to initiate ART using any one of the following ART regimens: AZT +3TC + NVP, AZT + 3TC + EFV and TDF + 3TC + EFV to prevent treatment failure. Since the prevalence of this treatment failure and its associated factor may be different from other ART centers and community in Ethiopia, further national representative institutional based cross-sectional researches are needed across all ART centers of Ethiopia in order to determine the prevalence of treatment failure and its associated factors.

Analysis of the long control region of bovine papillomavirus type 1 associated with sarcoids in equine hosts indicates multiple cross-species transmission events and phylogeographical structure.

Papillomaviruses are a family of slowly evolving DNA viruses and their evolution is commonly linked to that of their host species. However, whilst bovine papillomavirus-1 (BPV-1) primarily causes warts in its natural host, the cow, it can also cause locally aggressive and invasive skin tumours in equids, known as sarcoids, and thus provides a rare contemporary example of cross-species transmission of a papillomavirus. Here, we describe the first phylogenetic analysis of BPV-1 in equine sarcoids to our knowledge, allowing us to explore the evolutionary history of BPV-1 and investigate its cross-species association with equids. A phylogenetic analysis of the BPV-1 transcriptional promoter region (the long control region or LCR) was conducted on 15 bovine and 116 equine samples from four continents. Incorporating previous estimates for evolutionary rates in papillomavirus implied that the genetic diversity in the LCR variants was ancient and predated domestication of both equids and cattle. The phylogeny demonstrated geographical segregation into an ancestral group (African, South American and Australian samples), and a more recently derived, largely European clade. Whilst our data are consistent with BPV-1 originating in cattle, we found evidence of multiple, probably relatively recent, cross-species transmission events into horses. We also demonstrated the high prevalence of one particular sequence variant (variant 20), and suggest this may indicate that this variant shows a fitness advantage in equids. Although strong host specificity remains the norm in papillomaviruses, our results demonstrate that exceptions to this rule exist and can become epidemiologically relevant.
