Abstract. Given recent outbreaks of Oropouche virus in Latin America and >100 confirmed travel-associated cases in the United States, we evaluated the vector competence of US mosquitoes, including Aedes albopictus, Culex quinquefasciatus, Culex pipiens, and Anopheles quadrimaculatus. Results with historic and recent isolates indicates transmission potential by these species is low [only 1/50 Cx. pipiens transmitted virus].
Note: Similar to the literature, a low percentage of females became infected, but practically all were not able to transmit. This and similar reports indicate the risk of secondary transmission by mosquitoes from imported cases is very low.
