Low risk of transmission of prototype and newly emerged Oropouche virus strains by European Culex pipiens, Aedes albopictus, and Anopheles atroparvus mosquitoes.

ABSTRACT: Oropouche virus (OROV) is an emerging arbovirus of growing public health concern, with increasing incidence and geographic spread. Since its discovery in 1955, OROV has caused multiple outbreaks in South and Central America, with a new introduction in Cuba since May 2024. Recent travel-related cases in Europe and the Americas underscore its potential for global dissemination. Assessing vector competence outside endemic regions is critical in the context of global travel and climate change. We evaluated the vector competence of three mosquito species commonly found in Europe-Culex (Cx.) pipiens, Aedes (Ae.) albopictus, and Anopheles (An.) atroparvus-using two OROV strains: the prototype TRVL9760 (1955, Trinidad and Tobago) and a recent isolate OROV-IRCCS-SCDC_1/2024 (2024, imported from Cub
