According to The Guardian of 8 May: 'Heavy rains and severe flash floods have left more than 300 people dead and displaced thousands of others across parts of east Africa with Kenya and Rwanda being the worst hit. ...

The extreme weather has compounded a cholera outbreak in the country as well as an epidemic of the mosquito-borne chikungunya virus, and is increasing the risk of large-scale outbreaks.

The number of cholera cases reported since the beginning of 2018 stands at 2,943, with 55 deaths, according to the UN’s Office for Coordination of Humanitarian Affairs (Unocha).'
