Despite the critical role that water, sanitation and hygiene (WASH), waste disposal and environmental cleaning services play in the continuum of healthcare, access to WASH services globally remains alarmingly poor. UNICEF Eastern and Southern Africa Regional Office conducted a regional scoping study and deep dive on the enabling environment for WASH services in health care facilities across its 21 programming countries in Eastern and Southern Africa Region. The aim was to assess the status of the enabling environment for WASH services in health facilities, identify related gaps and explore avenues to enhance programming in the region.
