Reemergence of Human African Trypanosomiasis Caused by Trypanosoma brucei rhodesiense, Ethiopia.

We report 4 cases of human African trypanosomiasis that occurred in Ethiopia in 2022, thirty years after the last previously reported case in the country. Two of 4 patients died before medicine became available. We identified the infecting parasite as Trypanosoma brucei rhodesiense. Those cases imply human African trypanosomiasis has reemerged.

Prevalence of Post-Operative Trichiasis in Southern Ethiopia, 2021: A Community Based Cross Sectional Study.

Background: Post-operative trichiasis (PTT) is a major challenge following corrective eyelid surgery for trachomatous trichiasis. There is a scarcity of research on post-operative trichiasis in Southern Ethiopia, particularly in the study area. This study aimed to assess the prevalence of post-operative trichiasis in patients who underwent corrective surgery. Objective: To assess the prevalence of post-operative trichiasis in the Gamo Zone in Southern Ethiopia in 2021. Methods: A descriptive community-based cross-sectional study was conducted in the Dita district, Southern Ethiopia. The data were collected between 2014 and 2020. Three Qualified trachoma trichiasis (TT) graders working on a trachoma impact survey were recruited for this study. Eye examinations were performed by graders on all study subjects using a loupe to identify post-operative trichiasis. All patients underwent upper eyelid surgery only. A systematic sampling technique was used to select 459 participants from the TT Surgery Logbook. Results: Of the 459 study participants, more than three quarter 353 (76.9%) were female. The mean age of the study subjects was 48.38 years with a standard deviation of +-10.4. A total of 10 upper eyelids (7 bilateral and 3 left upper eyelids) underwent PTT. The prevalence of post-operative trichiasis in the study area was 2.2% (95% CI: 0.9-3.5%. Fourteen (4.7%) unoperated upper eyelids developed trichiasis infection. A few patients had left and right lower eyelid trichiasis (6/459 [1.3%] and 3/459 [0.7%], respectively). Conclusion and Recommendation: The prevalence of post-operative trichiasis in the study area was similar to that recommended by the World Health Organization (WHO) recommendation range. Trachoma trichiasis was observed on the lower and upper unoperated eyelids of the study participants. Therefore, sustainable interventions should be considered in the study area for all the components of the SAFE strategy, particularly on S component.

Soil-transmitted helminthiases among school-age children and their association with water, sanitation, and hygiene, Hawassa City, Southern Ethiopia.

BACKGROUND: Soil-transmitted helminthes pose the main health impact in tropical and sub-tropical regions, with children being at increased risk of infection. This study assessed the prevalence of soil transmitted helminthes among school children and their association with water, sanitation, and hygiene condition in Hawassa City, southern Ethiopia. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional study design was employed on randomly selected 549 school-age children from 11 schools by using a multistage sampling method. Data were collected using a structured questionnaire and observation checklist. Stool samples were collected and tested as fresh within 2 hours using the Kato-Katz technique as standard procedure. Data were analyzed by SPSS software; results were summarized using descriptive statistics, and a logistic regression model. Levels of considerable tests were determined with a 95% confidence interval and P-values <0.05. The overall prevalence of soil-transmitted helminthes was 49.7% (95% CI: 45.7%, 53.9%). Overall, water and latrines services were below the standard of 20 liters per person per day and one latrine seat per 50 boys and 25 girls respectively. In particular, no habit of washing hands with water and soap, 1.9%, (95% CI: 1.2%, 3.0%); inaccessible to safe drinking water, 10.8%, (95% CI: 3.96%, 30.26%); inaccessible to improved latrine, 10.8%, (95% CI: 1.5%, 78.4%); and practicing open defecation at school compound, 9.4%, (95% CI: 1.5%, 57.2%) were the main issues of concern observed. CONCLUSIONS/SIGNIFICANCE: Almost half of the studied children were infected with one or more soil-transmitted helminthes. Schools had inadequate water, sanitation, and poor personal hygiene practices. The infection by soil-transmitted helminthes among school children was high. This study has indicated that water, sanitation, and hygiene-related factors were the main risk factors for helminthes infestation in the study area. The school community needs to focus on actions that promote hygiene practices in the school.
