Emerging Infectious Diseases

Global climatic change and emerging infectious diseases

In addition to many human, biological, and ecological drivers, climate factors influence the emergence and re-emergence of infectious illnesses. Climatologists have seen rising global temperatures and now predict an extraordinary rise of 2.0 degrees Celsius by 2100. These changes have the potential to alter the introduction and spread of many dangerous infectious illnesses, which is a major source of concern. Mosquito-borne diseases, such as malaria, dengue fever, and viral encephalitides, are among the diseases most affected by climate change. Climate change would have a direct impact on disease transmission by altering the vector's geographic range, increasing reproduction and biting rates, and decreasing the incubation period of the virus. Increases in sea surface temperature and sea level caused by climate change can lead to a rise in the occurrence of water-borne infectious and toxin-related disorders, including as cholera & shellfish poisoning.
