WHO initiative to stop the spread of Anopheles stephensi in Africa
The spread of Anopheles stephensi (An. Stephensi) mosquitoes poses a significant threat to malaria elimination in Africa, according to a 2019 vector alert from the World Health Organization (WHO). This malaria vector, formerly only seen in South Asia and parts of the Arabian Peninsula, was detected for the first time in Africa in 2012, in the city of Djibouti. Over the last decade, An.stephensi has been expanding, with cases reported in five different countries on the African continent. To respond to this challenge, the WHO recently announced a new initiative aimed at halting the spread of this invasive mosquito species in the region.
