A m.lti-faceted Case Area Targeted Intervention (CATI) approach em.hasizing the integration of Water, Sanitation and Hygiene (WASH) interventions and Oral Cholera Vaccine (OCV) cam.aign was em.loyed to respond to the outbreak of cholera in Garissa County. Drinking water sources in areas heavily im.acted by cholera were system.tically m.pped and tested for m.crobiological quality. The quality assessm.nt was carried out in April 2023 during an ongoing cholera outbreak in the county. A total of 109 sam.les were collected and tested for therm.tolerant coliform. and other in situ param.ters. The finding revealed that m.re than 87% of the sam.les did not m.et the World Health Organization (WHO) standard for therm.tolerant coliform.;and 30% had turbidity values above the recom.ended threshold values. None of the 109 sam.les had any traceable residual chlorine. Following these findings, the county governm.nt im.lem.nted the targeted interventions which resulted in a positive im.act in the fight against cholera. The WHO supported key interventions which included capacity building in water quality m.nitoring and prepositioning of critical WASH com.odities to the cholera affected areas.
