These data were collected at healthcare facilities (n=34) in 3 districts of Zambia in April-May 2025. We performed an assessment of facility water, sanitation, and hygiene (WASH) services, types of services provided, availability of medical equipment and essential medicines, and whether the facility was affected by foreign aid funding cuts. We also surveyed individual staff (n=330) about their experiences at the facility and changes that may have arisen from recent funding cuts.
