Global climate change has had a considerable impact on infectious disease transmission in a number of ways. As with other climate change consequences on human health, climate change exacerbates existing inequities and challenges in controlling infectious diseases. Additionally, it increases the likelihood of several developing infectious disease concerns. Climate change may impact the spread of infectious diseases like dengue fever, malaria, tick-borne infections, leishmaniosis, and Ebola. There is no conclusive evidence that COVID-19 is getting worse or that climate change is to cause, despite continuous study. Global climate change has increased the number of instances of malaria and dengue, and this tendency is expected to continue as temperatures rise and more extreme weather events take place.
