First serological evidence of Crimean-Congo haemorrhagic fever virus in transhumant bovines in Italy.

ABSTRACT: Crimean-Congo haemorrhagic fever (CCHF) is an emerging tick-borne disease caused by the arbovirus Crimean-Congo haemorrhagic fever virus (CCHFV; family Nairoviridae). Given the public health impact, CCHF is considered a priority disease for the European Union. This study describes the first detection of anti-CCHFV antibodies in transhumant bovines in Italy. Sera from 794 cattle collected across Basilicata region (Southern Italy) were screened using a commercial ELISA kit. The animal-level and herd-level seroprevalences detected were 1.89% [95%CI: 1.12-3.1] and 29.63% [95%CI: 15.68-48.65], respectively. Results of the χ² test for trend show that the exposure to CCHFV was significantly associated with increasing age, with the odds 5 times higher in 11-22-year old cattle than 1-4-y
