Genetically modified mosquitoes, a potential antidote to deadly diseases

TRTWorld,  TRTWorld,  2022.

The US approved the release of billions of genetically modified mosquitoes to reduce the transmission of diseases but critics point to possible unintended consequences. Can genetically modified animals combat the spread of deadly diseases? The United States Environmental Protection Agency (EFA) thinks so. The agency has approved the release of over 2 billion mosquitoes that were genetically altered specifically to reduce the transmission of deadly transmissible diseases such as Zika, chikungunya, dengue, and yellow fever.The program in Florida and California will be put into action by the British biotechnology company Oxitec that genetically modify the mosquitos, mainly male Aedes aegypti eggs, in a lab. The mosquitos then will mate with females, only to pass the modified gene that would kill the female offspring. As a result, only the male offspring will stay alive as only the female ones spread the disease. The project also needs the approval of both states’ regulators and will be carried out in partnership with the Delta Mosquito and Vector Control district in Tulare county.
