This new study led by Dr Marianne Sinka (Senior Postdoctoral Researcher) mapped the potential extent of suitable habitats for the invading Asian malaria vector An. stephensi, recently identified in the Horn of Africa. Contrary to most African malaria vectors, An. stephensi is able to thrive in urban habitats and the study concludes that without swift action to halt its invasion, over 20 million additional people could be exposed to this deadly parasite.
