Which disease is likely to increase in prevalence because of climate change-related flooding?

Cholera is associated with increases in prevalence linked to climate change-related flooding due to its connection to water sources and sanitation conditions. When flooding occurs, it can overwhelm sanitation systems and contaminate drinking water supplies with Vibrio cholerae, the bacterium that causes cholera. This results in an environment fertile for cholera outbreaks, especially in regions where access to clean water and sanitation is already compromised.

Climate change is expected to intensify extreme weather events, including heavy rainfall and flooding, which leads to more frequent occurrences of such episodes. As a consequence, areas previously unaffected by cholera may experience outbreaks, increasing the disease's overall prevalence.

In contrast, other diseases mentioned, while influenced by a range of environmental and lifestyle factors, do not have the same direct correlation with flooding and waterborne transmission as cholera does. This makes cholera particularly susceptible to increases in prevalence due to flooding caused by climate change.
