According to the report in British Daily Mail on May 1, British biotechnology company implants "killer gene" in the Aedes aegypti which spread Zika virus in through genetic modification. Killer gene aegypti mosquito larvae make life shortened, so that the sharp drop in the number of vector mosquitoes to prevent the spread of Zika virus. At the same time, the number of one million mosquito variants will be sent to the United Kingdom the United States, released in Florida, aims to fight Zika virus.
Experiments show that in Brazil, the number of genes is altered mosquitoes dropped 90%, to achieve "an unprecedented degree of control."
World Health Organization has announced that Zika virus outbreak a public health emergency, pregnant women are also reminded not to travel to affected areas.
Zika virus is regarded as thousands of cases of infant cerebellar disease culprit, currently in South America the epidemic is serious threat to the United States are also being increased.
Biologist Derric Nimmo from biotechnology company Oxitec Nemo said, "We expect to release 3.3 million mosquito gene is altered in more than nine months during which we know very well the effect of this technology is currently the key is to expand and develop. release strategy."
It reported that the plan has encountered opposition. West Island section of Florida (Key West) residents said genetically altered insects on the environment and mankind unknown risks, mosquito release may scare tourists.
However, Dr. Amesh Adalja at University of Pittsburgh thinks that the fight of human against the vector mosquitoes spread diseases have been more than one century. Genetically-altered mosquitoe is a "pioneering" tool that can help to improve human life.
