First isolation of the Sindbis virus in mosquitoes from southwestern Spain reveals a new recent introduction from Africa.

ABSTRACT: Sindbis virus (SINV), is an Alphavirus of the family Togaviridae. This zoonotic arbovirus is transmitted by mosquitoes, primarily from the Culex genus, with bird species acting as amplifying vertebrate hosts. Occasionally it can also affect humans that are accidental hosts. SINV genotype I (SINV-I) has been isolated in mosquitoes and birds in South Africa and Northern Europe, producing fever outbreaks. In the last decades, there were several detections of SINV in Europe. In 2022, during the West Nile virus (WNV) mosquito surveillance program in Andalucía (Spain) implemented by the regional health administration, we detected the presence of both SINV and WNV in a Culex perexiguus pool, representing the first detection of SINV in Spain. After this finding, we scre
