Heavy rain has flooded 10 provinces in the DRC, with more wet conditions forecast over the coming days.
Nord and Sud Ubangui are among the most affected provinces and are also host to more than 130,000 Central African refugees.
260,000 people are affected in these two provinces, with an estimated 35,000 houses and 100 schools or health centres damaged or destroyed and 700 water points flooded.
Affected people are being hosted by family or friends, in public buildings or in makeshifts shelters. Cholera and/or malaria is endemic in the two provinces and the destruction of sanitation facilities and water points increases the risk of the spread of waterborne diseases as well as vector-borne diseases such as malaria.
The Congolese government is coordinating the response at national and provincial levels and a response plan has been developed in collaboration with humanitarian partners.
