Novel malaria vectors discovered in Western Kenya

A recent study has found novel vectors of the malaria parasite in Kisii Central District in the highlands of Western Kenya.

These mosquitoes — as yet unidentified — tended to bite outdoors and in the early evening. This ‘outdoor-active, early-biting’ behaviour could undermine current indoor-based malaria control measures and subsequently contribute to malaria parasite transmission in the area. The authors argue that examining the characteristics of local Anopheles spp., including behaviours, based morphological features and DNA analysis, will be important in determining whether the species is contributing to malaria transmission.
