As Temperatures Climb So Does Malaria

Increasing temperatures are now found to be increasing the size of the malaria infected areas, pushing the disease father uphill. Malaria infects about 300 million people per year and it can occur judging on the temperature, rainfall, vectors, parasites, human movement, standard of human health or economics. That would mean that in order to stop the disease scientists would have to try to eliminate all those types of causes, but they have trouble figuring out which ones actually cause it the most. Recent research suggests that temperature only plays a minor role on the mosquito-borne illness or that it wouldn’t cause an increase of the disease in different parts of the world. But another research project found that the Plasmodium parasite that causes it reproduces faster when it’s warmer and that the Anopheles mosquito that infects people with it thrives in higher temperatures. They also found a pattern that the occurrence of malaria infections going uphill into communities increases in hotter times of the year, but decreases in colder times. The main problem is that with climate change, cities that are settled in the mountains, like most in Asia, South America and Africa, will see more malaria problems.
