Following the cholera alert that was reported by the Director of Medical Services on 3 February 2015, a cholera outbreak was declared on 10 February 2015 in Migori and Homa Bay Counties.
A team from the Kenya FELTP comprising of Field Coordinators: Waqo Gufu Boru and Mark Obonyo and residents: Elvis Oyugi, Alfred Wandeba, Eunice Omesa, Joshua Muiruri, Tabitha Mwangi and Hudson Taabuk Kigen joined the Division of Disease Surveillance and Response (DDSR) in the investigation from 16 - 25 February 2015.
The analysis of the outbreak line list showed a delay in detection of the outbreak, possibly due to lack of laboratory capacity to confirm the outbreak. There was clustering of cases in East Kamagambo and East Kabuoch which rely on River Riana for their domestic water supply. The water from River Riana was contaminated with Vibrio Cholerae bacteria.
