Abstract:
Hepatitis E virus(HEV)is one of the most common pathogens in acute viral hepatitis.There are at least eight distinct genotypes of HEV.Only humans can contract HEV genotypes 1 and 2,but zoonotic viruses like genotypes 3 and 4 are mostly spread by eating undercooked or in-fected pork in some affluent nations.As a result,boars,both domestic and wild,are typically regar-ded as primary hosts of HEV.Nevertheless,during the past few years,a growing body of research has demonstrated that a number of other wild ruminant animals,such as wild deer and goats,are also susceptible to HEV infection.Determining their participation in the epidemiological cycle of hepatitis E thus requires an understanding of the risk variables that influence the transmission be-tween wild ruminants and humans.With an emphasis on published serological and molecular re-search,this review offers a broad summary of the body of knowledge currently available on the epi-demiology of HEV in wild ruminants.It addresses potential risk factors that could impact the spread of HEV among animals as well as their potential to serve as a source of infectious zoonotic illnesses.It presents an overview of the most recent developments in the epidemiology of HEV in wild ruminants and offers a framework for HEV prevention and management based on science.
