Co-Circulation of West Nile and Usutu Flaviviruses in Mosquitoes in Slovakia, 2018

Viruses. 2019 Jul 12;11(7):639. doi: 10.3390/v11070639.

Abstract

Monitoring West Nile virus (WNV) and Usutu virus (USUV) activity now has the highest priority among mosquito-borne pathogenic viruses circulating in the European Union. This study documents a first time detection and the co-circulation of WNV lineage-2 (with the minimal prevalence of 0.46%) and USUV clade Europe 2 (with the minimal prevalence of 0.25%) in mosquitoes from the same habitat of south-western Slovakia and underlines necessity to perform rigorous surveillance in birds, mosquitoes, horses and humans in that country.

Keywords: Culex spp.; Usutu virus; West Nile fever; West Nile virus; mosquitoes; surveillance.
