Description
Summary:Malaria experts and global health agencies are concerned about this spread because An stephensi is not only a good vector for Plasmodium falciparum and P vivax malaria parasites, but also it has several unusual traits that make it a formidable foe to defeat. Before the new vector's arrival, Djibouti was on the verge of malaria elimination, reporting only 27 cases in 2012. Since An stephensi was first detected, the country has “gone pretty rapidly away from that”, said Jan Kolaczinski, Head of the Vector Control and Insecticide Resistance Unit, Global Malaria Programme, WHO. In some surveys we’re doing in Sudan, we’re finding it's pretty much ubiquitous in urban settings, so it's spread very, very quickly and very extensively”, said Martin Donnelly, Head of the Vector Biology Department, Liverpool School of Tropical Medicine, UK, and Principal Investigator of Controlling Emergent Anopheles stephensi in Ethiopia and Sudan, a joint UK–African research project. [...]they are a naive population with no immunity to malaria.
