PIG333 22/05/17 Importance of Hepatitis E virus in pigs

Hepatitis E is caused by hepatitis E virus (HEV; taxonomic name Orthohepevirus A), a non-enveloped RNA virus in the Hepeviridae family. Based on WHO estimates, there are approximately 20 million HEV infections every year in people worldwide. Transmission of this virus occurs frequently via the oro-fecal route often associated with poor sanitation and contaminated drinking water. In humans, HEV is commonly associated with a mild short-term subclinical infection.

Signs of acute hepatitis E may include jaundice, fatigue and nausea and often manifests as self-limiting icteric illness. Table 1: Genotype classification of Hepatitis E virus (HEV) or Orthohepevirus A including host range, geographic distribution and zoonotic potential. In pigs, HEV was first identified in 1997 and to date it is recognized that genotypes 3 (most commonly), 4, 5 and 6 circulate in pigs and wild boars (Table 1).

Introduction Hepatitis E virus (HEV), the causative agent of hepatitis E in humans, is an important public health disease in many parts of the World [1,2,3,4]. Transmission is primarily via the fecal-oral route through contaminated food or water [5]. In developing countries in Asia and Africa, poor sanitation conditions lead to outbreaks of acute hepatitis E; however, sporadic and autochthonous cases of hepatitis E also occur throughout many industrialized countries in Europe, Asia, and North America [6,7]. In humans, the mortality rate ranges from 0.5–4% for immunocompetent individuals, however, mortality in HEV-infected pregnant women can reach up to 20% and immunocompromised individuals may develop a chronic HEV infection [8,9]. 2. 2.1. HEV belongs to the genus Hepevirus in the family Hepeviridae and consists of four recognized genotypes and at least two putative new genotypes [5]. 2.2. 3. 3.1. 3.2. 4. 5. 5.1. 5.2. 5.3. 6.

Hépatite E

L’Hépatite E est une hépatite virale (inflammation du foie) provoquée par une infection par un virus, le virus de l'hépatite E (VHE). L'infection par ce virus a été décrite pour la première fois en 1955 au cours d'une épidémie à New Delhi, en Inde[1]. Virologie[modifier | modifier le code] Les particules virales ont un diamètre de 27 à 34 nanomètres, n’ont pas d’enveloppe et contiennent un seul brin d’ARN et long d'environ 7 300 bases.

Ce génome est dit « de polarité positive » qui signifie que le génome viral est directement traduit par la machinerie cellulaire et sert directement d'ARN messager. Il a été classé initialement dans la famille des caliciviridae. Il existe plusieurs génotypes, numéroté de 1 à 4. Épidémiologie[modifier | modifier le code] L'hépatite E est très répandue dans la plupart des pays en développement et fréquente dans tous les pays au climat chaud. Les statistiques montrent pourtant que les cas sont en augmentation. CDC EID - SEPT 2009 - Hepatitis E Outbreak on Cruise Ship.
