Climate change helps spread mosquitoes

NEW YORK (Reuters Health) – A new study shows that up to one billion people worldwide, global warming threatens mosquitoes prone to disease.

The researchers said mosquitoes, the most common disease-transmitting species, including the Egyptian flock and the white whale, were carrying viruses such as dengue, zika and chikungunya, as well as more than a dozen others could become more serious over the next 50 years.

By creating a monthly model of global temperature changes, scientists have analyzed what could happen if these two types of mosquitoes moved with temperatures for decades.

"Although the numbers are difficult to calculate, we knew this would be a problem for a while," said co-author of the study, Colin Carlson, a professor at the Faculty of Medicine at the University of Toronto. University of Washington. "If there is a human side, we hope to have a different result."

According to the World Health Organization, mosquitoes carry millions of deaths each year. Dengue, zika and chikungunya cause symptoms such as fever, rash and severe muscle pain. For thousands of South American children exposed to the uterus.

Carlson and his team discovered that with global warming, mosquito-borne diseases could be transmitted year-round in the tropics and that seasonal outbreaks could occur almost anywhere. Nearly all of the world's population could be exposed to these diseases over a period of half the next century.

In the United States, where cases of zika have occurred in warmer areas in recent years, dengue and chikungunya could also spread, said Carlson.
