Heavy rainfall since mid-April has caused flash flooding and landslides across Kenya, affecting 36 of 47 counties. At least 237 people have died. The most affected counties are in the western and eastern regions of the country: Turkana, Kisumu, Lalamega, Siaya, Homa Bay, Tana River, and Garissa.?

The Nzoia River and Lake Victoria have burst their banks, with both bodies of water rising to the highest level seen in decades. An estimated 116,000 people are displaced. The majority of displaced are staying in temporary shelters, including schools and government-run evacuation centres, though shortages of shelters have been reported, forcing many to sleep in tents in open spaces.??

Floods and landslides saturated hundreds of hectares of crops and gardens, submerged thousands of homes, and destroyed WASH infrastructure across the affected area. Stagnant water from the flooding is likely to result in an increase in mosquito-borne diseases like malaria. Additionally, the inability to practice social-distancing among displaced populations increases vulnerability to COVID-19.?

The flooding comes in the peak of rainy season in East Africa and follows a particularly long and heavy rainy season that began in October 2019. The Government of Kenya has warned of continued rainfall and flooding through June. 

Latest Developments


A new wave of cholera has been confirmed in Marsabit and Turkana counties, including 25 cases in Kakuma refugee camp. As of 22 May, the total number of cases is unknown, but at least 13 people have died, mostly children younger than 10 years. Both counties have experienced flooding since April, leading to an increase in usage of contaminated water. This has likely contributed to the resurgence cholera following an outbreak that was reportedly contained in February.?

Key Priorities


Shelter: Approximately 116,000 people have been displaced, though that is likely an underestimate given that the exact number of damaged and destroyed houses is unknown. There is need for emergency shelter and NFIs.?

WASH: Water contamination and lack of access to sanitation facilities is a concern. The spread of water-borne illnesses is high as WASH infrastructure has been damaged and pit latrines are overflowing. Outbreaks of cholera have been reported in affected communities in Marsabit and Turkana. ?

Health: Mosquito nets, spraying of mosquito-prone areas, and additional protective equipment in emergency shelters are necessary. 

Humanitarian Access


Transportation and communications infrastructure has been disrupted, though the extent of the damage remains unknown. Humanitarian access continues to be a challenge due to flooded roads and bridges.?


Information Gaps and Needs


Widespread needs assessments have not been conducted due to access restrictions caused by flooding, damaged infrastructure, and continuing heavy rainfall.

The effect of the flooding on refugees and IDPs is unknown, though it is likely they have been affected and their needs increased by the rainy season.
