Climate change is affecting the distribution of these diseases due to the expanding geographic range and seasonality of these diseases and their vectors. [ 4 ] : 9 Though many infectious diseases are affected by changes in climate, vector-borne diseases, such as malaria, dengue fever and leishmaniasis, present the strongest causal relationship.
ENSO events can create cooler temperatures in the Western Tropical Pacific and warmer temperatures in the Central and Eastern Tropical Pacific leading to intense precipitation and storms. [26] Changes in climate due to ENSO can affect the dynamics of diseases and can affect the water sources humans use.
Climate change and conflict are hitting efforts to tackle three of the world's deadliest infectious diseases, the head of the Global Fund to Fight AIDS, Tuberculosis and Malaria has warned.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Pakistan witnessed the highest global increase in cases, with Ethiopia, Nigeria, Papua New Guinea and Uganda closely following suit.
In 2023, the WHO's World Malaria Report included a chapter on the link between malaria and climate change for the first time, highlighting its significance as a potential risk multiplier ...
Climate patterns influence the lifespan of mosquitos as well as the rate and frequency of reproduction. Climate change impacts have been of great interest to those studying these diseases and their vectors. [60] Additionally, climate impacts mosquito blood feeding patterns as well as extrinsic incubation periods. [54]
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
