What diseases will be affected by climate change?

Multiple factors determine the incidence of climate-sensitive infectious diseases such as malaria, dengue fever, Lyme disease, West Nile virus, and diarrheal diseases.

Why some diseases are likely to spread as a result of global warming?

Increasing carbon dioxide levels impact water and food supply, and a surge in diarrheal diseases can result. Most importantly, changes in ecology and biodiversity affect disease vector populations, potentially leading to higher rates of malaria, dengue, encephalitis, hantavirus, chikungunya, and more.

What are 3 problems caused by global warming?

Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.

How does global warming affect infectious diseases?

Mordecai’s research has found that warmer temperatures increase transmission of vector-borne disease up to an optimum temperature or “turn-over point,” above which transmission slows. Just as they carry different diseases, different mosquitoes are adapted to a range of temperatures.

What are the effects of global warming on people’s health?

Climate change increases the risk of illness through increasing temperature, more frequent heavy rains and runoff, and the effects of storms. Health impacts may include gastrointestinal illness like diarrhea, effects on the body’s nervous and respiratory systems, or liver and kidney damage.

What are infectious diseases?

Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They’re normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.
