Tessema RA, et al. - Researchers conducted a cross-sectional study examining the adequacy of improved sources of drinking water, sanitation, and hygiene practice for lowering diarrheal disease among people living with HIV/AIDS, Harar region, Ethiopia. 422 PLWHA in the Harar region related to WaSH as home-based care services and the prevalence of diarrheal disease using a standardized survey questionnaire. In the present study of 422 PLWHA in the Harar region, the 2-week prevalence of diarrheal disease was 25%, of which 16% reported two or more diarrheal episodes. Multivariate analysis releared lowering of the adjusted prevalence ratio of the 2-week prevalence of diarrhea by 8%, 7%, and 5% among PLWHA who have good hygiene practice, wash their hands with soap 24 hours before the survey, and use sanitation facilities consistently, respectively. Findings suggest inadequate access to improved drinking water sources, improved sanitation facilities, and hygienic practice among PLWHA; these trigger stakeholders for proper interventions, effective integration of adequate WaSH services to the HIV/AIDS program to improve the quality of life of PLWHA.
