Molecular characterization of flaviviruses from field-collected mosquitoes in northwestern Italy, 2011–2012

Abstract

Our findings confirm the circulation of Usutu virus and of the potentially zoonotic Marisma mosquito virus in Piedmont. This is the first detection of Aedes flavivirus in Piedmont. Finally, further evidence for the integration of Flavivirus nucleic acid into the host genome has been shown. These results underline the importance of continuing intense mosquito-based surveillance in Piedmont, supported by a mosquito control program in areas at high risk for human exposure.
