Genetically modified mosquitoes will reduce the risk of contracting fever

Significant progress has been made in the fight against dengue-carrying mosquitoes at Oxitec, a British biotech company. The result of mating of males bred in her laboratories with ordinary females appears offspring, which die before reaching the ability to carry the infection.

It took over a decade to develop this mosquito control method. It was based on the results of the successful destruction of mosquitoes in the Cayman Islands in 2010.

This success is of great importance for the inhabitants of tropical countries, since today there are no effective treatments for dengue fever, which causes severe joint pain and affects the circulatory system. During the year, the number of mosquitoes carrying fever dropped by 95%. The experiment was carried out in northeastern Brazil near the city of Juazeiro.

Brazil was chosen to conduct the experiment because up to 16 million infections annually are recorded there. Disease-carrying mosquitoes are immune to most pesticides, and the infection is spreading in very poor areas, where the administration cannot devote enough funds to control its vectors.
