A recent study by Spanish researchers has discovered a high rate of Crimean-Congo hemorrhagic fever virus (CCHFV) exposure among wild boar populations in southwestern Spain, suggesting the virus is endemic and widely circulating in the area. Through antibody testing and PCR, the research revealed a significant difference in seroprevalence between wild boars (39.7%) and Iberian domestic pigs (2.8%), indicating that wild boars are a major reservoir for CCHFV, while domestic pigs have a minimal role in its spread. These findings highlight the need for enhanced biosecurity and surveillance programs to monitor the virus and protect human health.

Crimean-Congo hemorrhagic fever virus (CCHFV) is an emerging pathogen transmitted primarily by ticks of the genus Hyalomma. This arbovirus is the causative agent of Crimean-Congo hemorrhagic fever (FCHF), a severe and fatal zoonotic and hemorrhagic disease in humans. In Europe, human cases of FCHF have traditionally been reported only in southeastern countries. However, shortly after the virus was detected in Spain in Hyalomma lusitanicum ticks collected from deer (Cervus elaphus) in 2010, human clinical cases have been confirmed in the west and southwest of the country since 2013. Few studies have evaluated CCHFV circulation in deer and wild boar. Furthermore, these two species of wild ungulates usually coexist with domestic Iberian pigs raised extensively, so direct and indirect contact between these sympatric species is frequent. The majority of Iberian pig farms (80%) are located in the southwest of Spain, where CCHFV circulation is high. For this reason, a group of ...
