Cholera remains a significant public health concern in Kenya. Since 1 October 2025, over 231 cases and 13 deaths were reported across three counties, including Narok, one of the hardest hit. To curb transmission, the Ministry of Health, with support from the World Health Organization (WHO), the Kenya National Public Health Institute, the Kenya Red Cross Society and Médecins Sans Frontières, conducted a reactive oral cholera vaccine campaign in Transmara West and Transmara South, targeting residents aged one year and above.
