The warmer, wetter and more variable conditions brought by climate change are therefore making it easier to transmit diseases such as malaria, dengue fever, chikungunya, yellow fever, Zika virus, West Nile virus and Lyme disease in many parts of the world.
How does climate change increase infectious disease?
Warming climates increase the range within which a disease can find a home, especially those transmitted by “vectors,” mosquitoes and ticks that carry a pathogen from its primary host to its new victim.
How is disease affected by climate change?
The health effects of these disruptions include increased respiratory and cardiovascular disease, injuries and premature deaths related to extreme weather events, changes in the prevalence and geographical distribution of food- and water-borne illnesses and other infectious diseases, and threats to mental health.
How does temperature affect infectious diseases?
Longer seasons of mild temperatures may increase the transmission likelihood of vector-borne diseases. In warmer temperatures, vectors become infectious more quickly and can transmit virus earlier in their lives .
How does climate change affect Vector Borne Diseases?
Rising global temperatures can lengthen the season and increase the geographic range of disease-carrying insects. As temperatures warm, mosquitoes and other warm-weather vectors can move into higher altitudes and new regions farther from the equator.
What are 5 effects of climate change?

- rising maximum temperatures.
- rising minimum temperatures.
- rising sea levels.
- higher ocean temperatures.
- an increase in heavy precipitation (heavy rain and hail)

What are climate sensitive infectious diseases?
The process of quantitative analysis therefore focused on three categories of climate-sensitive infectious diseases: diarrheal illness, vector-borne diseases and leptospirosis.
Which infectious disease is indirectly caused by climate change?
The major mosquito-borne infectious diseases that have been reported to be affected by global warming include malaria, dengue fever, Japanese encephalitis (JE), and tick-borne encephalitis.
How does climate change affect the spread of malaria?
An increase in temperature, rainfall, and humidity may cause a proliferation of the malaria-carrying mosquitoes at higher altitudes, resulting in an increase in malaria transmission in areas in which it was not reported earlier.
What is the consequence of climate change on biotic component of the ecosystem?
Many studies demonstrate unequivocally that global warming is shifting the distribution of animal and plant species, affecting the composition not only of natural ecosystems but of agricultural ones as well, and also altering the range and impact of pathogenic organisms.
