Twenty-five people were still missing and 26 others had been rescued after devastating floods in Elgeyo-Marakwet County, government spokesperson Isaac Mwaura said in a statement. Most of the rescued people were receiving treatment.
The government has deployed military planes and disaster response specialists to conduct a search and rescue operation, Mwaura added.
Hundreds of people have been killed in recent years in landslides and flooding in Kenya, with scientists saying climate change is causing more intense and frequent extreme weather events.
In the worst incident last year, 61 people were killed in a mudslide and flash floods in central Kenya.
Landslides in the east of neighbouring Uganda have also killed at least 13 people in the last week, according to the Uganda Red Cross.
