Almost 1 billion people could suffer from dengue as a result of climate change, warned of monitoring. T


About 1,000 million people they will be open to diseases like this Confidential fever in the late 21st century, as global temperature rises, according to a survey published today in the same edition. Plossal Tropical Diseases.

"Climate change It is the largest and most comprehensive a threat to health security world Mosquitoes are not part of the challenge alone, but after the Zika violation in Brazil in 2015, we are particularly concerned about what is happening, "said lead author Colin Carlson from t University of Georgetown (USA).

It examined the future if the two most common mosquitoes behave dengue, t Aedes aegypti and Aedes albopictus, they move in the places as the global temperature changes over decades.

According to the World Health Organization (WHO), the mosquito is one of the deadliest animals in the worldbecause it causes diseases that cause millions of deaths a year.

Both Aedes aegypti as the Aedes albopictus they can produce the dengue, chikungunya and zika viruses, as well as at least more than a dozen other diseases that may appear, according to the researchers, to be Some 50 risks over the next 50 years.

With global warming, scientists say, t almost every number of the world might be open at one time in the next 50 years.

As the temperature rises, experts say that movements will take place during the year in the tropics and seasonal hazards in almost all locationsadditionally, the diseases are closer.

“These diseases, which we are considering are completely tropical, t has already appeared in suitable climate areas, such as Florida, t because the two people are very good at moving both insects and pathogens around the world, "the authors expressed.

In fact, there are places Europe, North America and the tropics that have been too cold for viruses against new diseases such as dengue will have high elevations.

Another investigator, Sadie Ryan, of Florida University, argued that the work is recommending climate change is recommended. "This will significantly increase the amount possible and “tightening” the spread of the viruses that spread to Aedes mosquitoes in the next century.

The researchers' results show that the range of mosquitoes is moving within the best temperature levels for distribution (between 21.3 and 34 degrees Celsius for the temperature). Aegypti and between 19.9 and 29.4 ° C for the. t Albopictus) be expected changes in the distribution of viruses distributed.

“The expectation is that diseases will be spread to people growth in Europe, spread Albopictus It could be reduced in south-east Asia and in West Africa in the worst case scenario for researchers, ”Ryan said in his views. t
