According to a study published this Monday, September 14, tens of millions of inhabitants of African cities are threatened by “anopheles stephensi”, a malaria vector mosquito native to Asia and particularly adapted to the urban environment.

In Africa, malaria is often concentrated in rural areas. But, this trend is likely to change soon. The Anopheles stephensi as for it learned to exploit the water reservoirs of the cities (especially those made of cement and bricks), where it sneaks through the smallest hole to deposit its larvae. “It is the only species to have succeeded in penetrating central urban areas”, explains medical entomologist Marianne Sinka, Researcher at the University of Oxford in her study published by the American scientific journal PNAS.

“44 cities are highly adapted to the insect and 126 million Africans who are today spared are at risk, mainly in the equatorial region. The 40% of people who live in urban areas could suddenly be vulnerable and infected with malaria, it would be very serious, ”the study said.
