Key result
The overall prevalence of HEV infection in wild boars was 23.2%, with a significantly higher risk of infection during the early hunting season compared to the late season (OR 44.73).
Population
142 hunted wild boars from 12 hunting areas in Andalusia (southern Spain) during the 2015/2016 hunting season

HEV infection is highly prevalent in wild boars in southern Spain and exhibits a seasonal pattern, peaking in autumn, which may influence zoonotic transmission risk.
Rivero‐Juárez et al. (2018) conducted a cross-sectional in Hepatitis E virus (HEV) infection (n=142). Early hunting season (Oct 15 - Nov 15) vs. Late hunting season (Jan 16 - Feb 15) was evaluated on HEV infection (amplification of HEV RNA in serum by RT-PCR) (OR 44.73, 95% CI 8.49-235.53, p=<0.001). The overall prevalence of HEV infection in wild boars was 23.2%, with a significantly higher risk of infection during the early hunting season compared to the late season (OR 44.73).
