Hotspot of Crimean-congo hemorrhagic fever virus seropositivity in wildlife, northeastern Spain

Abstract

We conducted a serosurvey for Crimean-Congo hemorrhagic fever virus antibodies in various wildlife species in Catalonia, northeastern Spain. We detected high seroprevalence in southern Catalonia, close to the Ebro Delta wetland, a key stopover for birds migrating from Africa. Our fi ndings could indicate that competent virus vectors are present in the region.
