Role of invasive Aedes (Aedimorphus) vittatus in chikungunya virus transmission in the newly-invaded coastal island city of Mombasa, Kenya.

ABSTRACT:

Background

Countrywide routine entomological surveillance studies in Kenya from 2006 first identified Aedes vittatus, in small numbers (4 specimens), in Mombasa city in 2014 during a dengue outbreak investigation. Significant numbers (1,648 specimens) were collected in January 2018 during a chikungunya outbreak investigation. The presence of Ae. vittatus, and a competent vector of chikungunya virus, complicates disease epidemiology and control efforts in Mombasa underscoring the need to determine its bionomic factors.

Methods

In June 2021 and December 2021, we conducted mosquito sampling at multiple sites in Mombasa, an island city county, using CO₂-baited Biogent sentinel (BGS) traps and human landing collection (HLC) methods. The collected mosquitoes were identified morpho
