Hepatitis E Virus in the Wild Boar Population: What Is the Real Zoonotic Risk in Portugal?

Ana Carolina Abrantes,
Sérgio Santos-Silva,
João Mesquita
et al.

Abstract: Hepatitis E virus (HEV) is an important zoonosis in wild boar. Reported zoonotic cases are mainly associated with the consumption of raw/undercooked meat and/or liver. This study aims to determine the occurrence of HEV in the Portuguese wild boar population. During the hunting season 2021/2022, 123-matched samples (liver, faeces, and blood) were collected from hunted wild boars throughout Portugal. An RT-PCR assay tested liver and faeces samples to detect HEV-RNA. From blood samples, an ELISA test was performe… Show more

“…However, there was no statistically significant association between gender and HEV RNA detection among the livestock recruited in this study. Furthermore, the detection rate of HEV RNA in stool samples of both swine and poultry birds aged 1-6 months agreed with the findings of Martelli et al, (42), Owolodun et al, (19) and Abrantes et al, (43). However, both swine and poultry birds aged 7-12 months had a higher rate of HEV RNA in our study, suggesting that HEV could be circulating in all age groups and that swine that are close to slaughtering age can still be HEV-infected (44)(45)(46)(47)(48)(49).…”
