The increase in global temperature will bring the people to this disease

, 1 April (EUROPA PRESS) –

Up to a billion people could be exposed to mosquitoes carrying disease before the end of the century as a result of global warming, according to a new study investigating temperature changes per month across the country. T the world. The authors say that even in areas of limited risk of sufficient climate for mosquitoes, the viruses are bad, as the viruses that they carry are infamous of explosive expeditions when the exposure arises. the correct place under the correct conditions.

"Climate change is the biggest and most significant threat to global health protection," said Colin J. Carlson, a change of international expert in the Department of Biological Studies at Georgetown University in the United States and a combination of climate change. In the new study. “Mosquitoes are just part of the challenge, but after the Zika violation in Brazil in 2015 we are especially concerned about what is happening,” he said.

Published in the access journal PLOS Neglected Tropical Diseases & # 39; ("Expanding the world and re-spreading the threat that the virus will be spread by climate change), the research team managed by Sadie J. Ryan, t since Florida University, in the USA, and Carlson studied what would happen if the two mosquitoes that carry diseases are more common, Aedes aegypti & 39; Aedes albopictus, keeping an eye on movement as temperatures change for decades.

According to the World Health Organization (WHO), mosquitoes is one of the world's deadliest animals and causes disease that causes millions of deaths each year. Aedes aegypti & 39; and 'Aedes albopictus'; to spread the dengue, chikunguyna and Zika viruses, as well as at least a dozen other diseases that all the researchers have said are in danger in the next 50 years.

STRATEGY FOR CHILDREN'S STRATEGY FOR YEARS ONLY

With global warming, scientists say that almost everyone around the world could appear at some point in the next 50 years. As temperature increases, it is expected that transmission throughout the year will increase in the tropics and seasonal risks almost everywhere. It is also thought that larger infections are found.

“These legacies, which we are considering completely tropical, have already appeared in suitable climate areas, such as Florida, because people are very good at moving insects and pathways across the world. , "Ryan said, a professor in Medical Studies at the University of Florida.

"The transmission of the disease is a real problem, even in the decades to come," said Carlson, "places like Europe, North America and the high heights in the tropics which may have occurred." too cold for viruses new diseases like dengue. "

More severe climate change would threaten the worse population for mosquito Aedes aegypti. But in areas with the worst weather increases, including West Africa and South Asia Asia, it is expected that there will be a big reduction in mosquito 'Aedes albopictus', that's good! unique in East Asia and West Africa. This mosquito carries dengue, chikunguyna and Zika.

The team of researchers examined the temperatures month to month to push the risk to 2050 and 2080. The model did not think about the type of mosquito that would move, but it represented an environment where no-one would be in motion. exclusion.

“Based on what we know about the movement of mosquitoes from one area to another, it is 50 years long and we expect large exposures of both types of insect, particularly 'Aedes aegypti', which is working in urban environments, "said Carlson.

"This is just an investigation to start understanding the challenges quickly arising from global warming," Carlson says, "we have a Herculean work ahead of us." We need to trace pathogen patches, region by region, when they encounter difficulties in planning a global health response.
