Serendipitous detection of Anopheles stephensi in Kisumu, Kenya in June 2022

In June 2022, a pool of five mosquitoes that were morphologically classified as Anopheles gambiae and caught in Kisumu (Kenya) were tested for blood-meal analysis. Of the 19.6% (11/56) amplicon sequence variants assigned to mosquito species using basic local alignment search tool (BLAST), one had 15 hits matching Anopheles stephensi. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study was funded by the Stanford University Center for Innovations in Global Health Seed Grant 2021 and the Robert E Shope ASTMH (American Society of Tropical Medicine and Hygiene) to Dr. Keli Nicole Gerken. ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.
