In this post in Management Sciences for Health’s (MSH) “Global Health Impact” blog, Abdul Qawi Qadiri, WASH coordinator for Baghlan Province in Afghanistan, writes about how a community-led program in the village of Baghalak has helped to reduce the incidence of infectious illnesses, particularly diarrheal diseases. The USAID-funded program, Sustainable Water Supply and Sanitation (SWSS), is a community-led total sanitation (CLTS) training aimed at increasing the use of latrines and other hygienic practices, Qadiri notes (8/7).
