Serological evidence of Crimean-Congo hemorrhagic fever and West Nile virus in livestock in Danube Delta: preliminary results

Abstract

Crimean–Congo hemorrhagic fever virus (CCHFV) and West Nile virus (WNV) are emerging arboviruses of significant public and veterinary health concern in Europe, with increasing evidence of circulation in southeastern regions. The Danube Delta, characterized by extensive wetlands, migratory birds, wildlife reservoirs, and high vector density (Hyalomma spp. ticks and Culex spp. mosquitoes), represents a hotspot for arboviral emergence within a One Health context.
