Scientists are manipulating the DNA of mosquitoes to fight the spread of malaria

R. Min,  EURONEWS.NEXT,  2022.

Scientists say they have managed to genetically modify mosquitoes so that they are unable to spread malaria, a disease that kills well over half a million people each year. The changes cause mosquitoes to live shorter lives, while the parasites inside them, which cause the fatal infection, develop more slowly. This slashes the chances of mosquitoes living long enough to carry fully grown parasites – and transmit the disease to the humans they bite.Malaria is spread by the parasite Plasmodium falciparum, which grows and reaches maturation inside the female Anopheles mosquito. The average mosquito survives on average seven to 10 days in the wild. “By prolonging the developmental time that the parasite needs inside the mosquito to become infectious, this 10 per cent becomes now much smaller”.
