HEV is the major cause of enterically transmitted hepatitis world wide, and is not limited to countries with low sanitary standards. HEV has been detected in environmental samples (water) in several countries from Europe and Asia, representing a risk factor for waterborne infection. While hepatitis E virus infections are relevant in Europe, knowledge about epidemiology of hepatitis E virus infections in the USA and Latin America is still limited <a class="elsevierStyleCrossRef" href="#bib0040">[1]</a>.</p><p id="par0010" class="elsevierStylePara elsevierViewall">The HEV is classified in the genus Orthohepevirus, with four species that affect different hosts (A–D). The specie with the highest rank of hosts is Orthohepevirus A, which includes 7 reported genotypes that infect humans (1, 2, 3, 4 and 7), pigs (3 and 4), rabbits (3), wild boar (3, 4, 5 and 6), mongooses (3), deer (3), yaks (4) and camels (7) <a class="elsevierStyleCrossRef" href="#bib0045">[2]</a>. Genotypes 1 and 2 are responsible for epidemics outbreaks, mainly in developing countries, and have been isolated from humans exclusively, zoonotic transmission due to contact with infected animals and consumption of contaminated undercooked or raw meat has been identified as an important risk factor, especially in industrialized countries <a class="elsevierStyleCrossRef" href="#bib0050">[3]</a>.</p><p id="par0015" class="elsevierStylePara elsevierViewall">HEV affects mainly young and middle aged adults, mainly between 15 and 40 years of age, however, cases of chronic infection of HEV have been reported in immunosuppressed people, as in people with chronic liver disease, organ transplantation or people infected with the human immunodeficiency virus in which the disease rapidly evolves to liver cirrhosis, loss of the transplanted organ and death.
