Abstract: Hospital acquired infections (HAI) pose a significant threat to the health of patients and health care employees in developing countries. Limited resources are available for health facilities: It is estimated that 15% of patients in low-income countries develop one or more infections during a hospital stay, of which water, sanitation and hygiene (WASH) is a contributor (Allegranzi et al., 2011). Infections account for a third of the 3.6 million neonatal deaths each year and for 15% of maternal deaths (Lawn et al., 2010). In 2016 Ministry of Health and UNICEF started a pilot project in 55 Zambian health care facilities implementing basic WASH infrastructures including disinfectant production, waste management and hand washing to effectively prevent diseases. A specific focus was given to mother and child health to reduce burden of disease by autonomous production of sodium hypochlorite, using electrolysis to transform saline solution into disinfectant with WATA technology.
