Disease!!!!! Disease!!!! Disease!!!! Living on this earth we are exposed to a lot of different infectious Disease. Hepatitis E is a very serious liver disease caused by the Hepatitis E virus (HEV) that usually results in an acute infection.(http://www.cdc.gov/hepatitis). It’s safe to safe to say that Hepatitis E does not lead to a chronic infection according to CDC. In this research paper I will identify the causative agent, geographical distribution, transmission, clinical features, diagnosis, treatment, and the control measures of this serious liver disease. Key facts about Hepatitis E may include:
• Every year there are 20 million hepatitis E infections, over 3 million acute cases of Hepatitis E, and 57,000 hepatitis E related deaths.
• Hepatitis E is found worldwide, but the prevalence in highest in East and South Asia
• Hepatitis E is usually self limiting but may develop into fulminant hepatitis and is transmitted via faecal-oral route, principally via contaminated water.
• China has produced and licensed the first vaccine to prevent hepatitis E virus infection, although it is not yet available globally.
The Causative Agent
The causative agent for hepatitis E is the Hepatitis E virus (HEV). According to my research the virus originated from the stool of a volunteer orally infected with faces from suspect cases of non-A and non-B hepatitis (Balayan et al. 1983) hepatitis E virus is a non-eveloped, positive-sense, single-stranded ribonucleic acid (RNA) virus is approximately 27 to 30 nm in size (veterinami medicina 52, 2007) (HEV) infections are spreads by the faecal – oral route and causes acute sporadic and epidemic viral hepatitis worldwide, usually through contaminated water supply. (Vasickova et al, 200...

...s first observed and described in 1983(Balayan et al., 1983). The virus has been extensively investigated since that time. After a long-termeffort to assign this virus to a taxonomic class, the virus has been classified in the Hepevirus genus, Hepeviridae family in 2004 (Emerson et al., 2004;http://www.ncbi.nlm.nih.gov/ICTVdb/Ictv/fs_hepev.htm).
Anti-HEV antibodies (or viral RNA) have not only been found in people, but also detected in
various animal species (Arankalle et al., 1994,2001; Favorov et al., 1998).
