Abstract: Hepatitis E virus (HEV) is one of the most frequent causes of acute viral hepatitis of enteric transmission worldwide. In South America the overall epidemiology has been little studied, and the burden of the disease remains largely unknown. A research of all scientific articles about HEV circulation in South America until November 2017 was carried out. Human seroprevalences of HEV varied according to the studied population: blood donors presented prevalence rates ranging from 1.8% to 9.8%, while reports from H… Show more

“…Such age criterion was followed since breastfeeding confers HEV infection immunity to newborns and, in general, animals older than 6 months have already acquired immunity (Vitral et al, ). Our data confirm the circulation of HEV genotype 3, as occur in border or neighbour countries, although with a lower infection rate (Pisano, Santiago, et al, ). However, it is worth mentioning that HEV detection results can be influenced by the nature of the sample analysed.…”

“…Thus, HEV constitutes a risk for these populations, emerging as a public health issue. Emphasizing this, multiple reports have shown that such immunosuppressed individuals present a higher HEV prevalence, compared to the general population (Munné et al, ; Pisano, Santiago, et al, ).…”

“…The seroprevalence rates in many European countries ranging from 1.3% to 52% have been reported. Similarly, seroprevalences of HEV in blood donors ranging from 1.8% to 9.8% in South America, 3.4% to 30% in several Asian countries have been reported. The current study from India, a developing country, showing a prevalence rate of 17.70% goes at par with rates reported in several Asian countries attributing to similar endemicity of HEV infection.…”

“…Four genotypes (HEV-1, HEV-2, HEV-3, and HEV-4) of the species Orthohepevirus A are associated with human illness. HEV−1 and HEV−2 are restricted to humans and are prevalent in regions with poor water sanitation, such as the developing countries of Asia, Africa, South and Central America (Hartl et al, 2016;Pisano et al, 2018). On the other hand, HEV-3 and HEV-4 are considered to be zoonotic pathogens as they have a much wider range of mammalian hosts including, among others, domestic and wild swine and ruminants (Park et al, 2016;Sooryanarain and Meng, 2019).…”
