diseases caused by floods
Floods can potentially increase the transmission of the following communicable diseases: 1  Water-borne diseases, such as typhoid fever, cholera, leptospirosis and hepatitis A. 2  Vector-borne diseases, such as malaria, dengue and dengue haemorrhagic fever, yellow fever, and West Nile Fever.his was probably because the flood was complicated by population displacement. Floods in Mozambique in January-March 2000 led to an increase in the incidence of diarrhoea and in 1998, floods in West Bengal led to a large cholera epidemic (01,El Tor, Ogawa).
