**c. Water-related problems of climate change**

Climate change induces profound changes in the volume of water available in a given area, which can materialize either through heavy rainfall and flooding or through drought leading to a scarcity of water in this area for the domestic use of the population and for animals. Floods generally carry certain infectious and parasitic diseases, including vector-borne diseases that are closely linked to the proliferation of mosquitoes and other vectors. Many outbreaks of waterborne diseases are due to the mobilization of pathogens or extensive contamination of water by fecal bacteria such as salmonella and coliforms. Thus, it is not uncommon to observe in Haiti outbreaks of anthrax or anthrax following cyclones and also an abnormally high number of gastrointestinal-dominated pathologies dominated by gastrointestinal disorders. Such contamination has generally had unfortunate consequences on the health of the population by rendering catchment waters that were intended for human consumption completely undrinkable.

Water-borne diseases are not necessarily related to floods since the lack of water can prevent daily hygiene practices, especially at the time of the new coronavirus pandemic or in countries where cholera is still prevalent. This lack of water, in some areas, can be extremely serious for the health of the population because it is important to wash your hands with soap and water several times a day to protect yourself against these two diseases.
