Infectious Diseases are Affected by Climate Change in Which Ways

Question

Infectious diseases are affected by climate change in which ways?
A) Their local and global distributions
B) Intensity
C) Prevalence
D) Load

Accepted Answer

Climate change can impact the local and global distribution of infectious diseases, as shifts in temperature and rainfall can alter the habitat range of disease vectors and hosts. Changes in temperature, rainfall patterns, and extreme weather events can also affect the intensity of infectious diseases by affecting the reproduction and survival rates of disease vectors and improving the conditions for their growth and transmission. Additionally, changes in climate can affect the prevalence of infectious diseases by destabilizing local ecosystems, altering the availability of food and water sources, and leading to population displacement, which can increase exposure to diseases. Therefore, all of the listed choices apply when it comes to the impact of climate change on infectious diseases.
