Dengue fever is a viral disease, widespread in tropical and subtropical regions. It is characterized by sudden fever, which lasts 5-7 days, headache, severe pain in joints and muscles, sometimes a rash. This is followed by a period of physical exhaustion and depression lasting at least a week.
The most unpleasant is the fact that fever spread by mosquitoes. So, in the case of expansion of their range, victims of fever can be thousands of people.
Instead of trying to develop a vaccine against the fever, scientists from Oxford University decided to deal with vectors-mosquitoes. Using genetic modification they were able to deprive the wings of female mosquitoes, reports Associated Press.
Researchers have created a genetic modification of the male mosquitoes of the species Aedes aegypti, paired them with females and got a result of “defective” offspring. So the females have underdeveloped wings and can’t fly, which quickly died. In males, the wings were normal, but their scientists have been denied the opportunity to bite.
According to scientists, this method, based on genetic modification can be used with other mosquito species, particularly those that spread malaria and West Nile
