- Adequate clean water, improved sanitation infrastructure, and better hygiene may significantly improve health outcomes for people living with HIV (PLHIV) in resource-poor settings. Catholic Relief Services Malawi, with support from the World Health Organization and the United States Agency for International Development (USAID), implemented a pilot project to identify household scale changes or actions that could improve WSH conditions for PLHIV. An evaluation showed substantial changes in six targeted behaviors and a reduction in the overall prevalence of diarrhea, suggesting that this is an effective approach to ameliorating WSH conditions for those affected by HIV.
