Some types of hepatitis E virus are spread by drinking water contaminated by an infected persons stool. Hepatitis E is an enterically transmitted infection that is typically self-limited.
The hepatitis E virus HEV is a small RNA virus and the etiological agent for hepatitis E a form of acute viral hepatitis.
Pathophysiology of hepatitis e. Hepatitis E is a RNA virus in the family Hepeviridae. It has a 50 day incubation period. It is spread via fecal oral route through contaminated water or uncooked meat.
It is most common in Asia and Africa. The severity is mild and disease is usually not chronic but if severe enough can lead to acute liver failure of chronic hepatitis. Acute hepatitis E has been noted to progress to chronic disease in HIV infected patients with a low CD4 count.
Solid organ transplanted patients are commonly asymptomatic or have mild symptoms of the disease. 60 of infected patients with an organ transplant develop chronic hepatitis. HEV has an incubation period of 2-10 weeks.
21 Acute HEV infection is generally less severe than acute HBV infection and is characterized by fluctuating aminotransferase levels. Although most hepatitis E virus HEV infections are asymptomatic some can be severe causing fulminant hepatitis and extra-hepatic manifestations including neurological and kidney injuries. Chronic HEV infections may also occur in immunocompromised patients.
Hepatitis E virus HEV is the most common cause of acute viral hepatitis throughout the world. Most infections are acute but they can become chronic in immunocompromised patients such as solid organ transplant patients patients with hematologic malignancy undergoing chemotherapy and those with a human immunodeficiency virus HIV infection. Hepatitis E is an enterically transmitted infection that is typically self-limited.
1 2 It is caused by the hepatitis E virus HEV and is spread by fecally contaminated water within endemic. Hepatitis A virus HAV and hepatitis E virus HEV cause acute self-limiting hepatic infections that are usually spread by the fecal-oral route in humans. Naturally occurring and experimental infections are possible in a variety of nonhuman primates and in the case of HEV a number of other species.
Many advances in understanding the. Hepatitis is an inflammation of the liver most commonly caused by a viral infectionInflammation is the bodys response to injury or irritation. Viruses are responsible for hepatitis in which differ from one another in some ways to share several traits First they generally infect only hepatocytes and then on the other side bacteria can infect different parts of the body.
Hepatitis E virus HEV infection results in hepatitis E an acute and self-limited disease. The virus is transmitted in a faecaloral manner and is a major cause of viral hepatitis in much of the developing world where it causes rampant sporadic infections and large epidemics. The hepatitis E virus HEV is a small RNA virus and the etiological agent for hepatitis E a form of acute viral hepatitis.
The virus has a feco-oral transmission cycle and is transmitted through environmental contamination mainly through drinking water. Recent studies on the isolation of HEV-like viruses from animal species also suggest zoonotic. Hepatitis is inflammation of the liver tissue.
Some people or animals with hepatitis have no symptoms whereas others develop yellow discoloration of the skin and whites of the eyes poor appetite vomiting tiredness abdominal pain and diarrheaHepatitis is acute if it resolves within six months and chronic if it lasts longer than six months.

Historically hepatitis E virus HEV has been known to cause acute hepatic inflammation almost exclusively. Usually in a self-limiting fashion that may infrequently progress to fulminant hepatitis. Transmission is predominantly through the fecal-oral route through contaminated water.
Hepatitis A Virus can be eliminated by heating contaminated foods to 185 F 2. Hepatitis C 75 are asymptomatic until the disease has progressed to a chronic state 3. Hepatitis D Only present if the patient also has HBV infection 4.

Viral hepatitis a disease caused due to liver inflammation is amongst leading human global health threats. A diverse group of viruses spreading through different routes and having a wide range of reservoirs may cause hepatitis in humans accounting for death and disability as well as a huge economic loss. Hepatitis E is typically an acute infection that gets better without treatment after several weeks.
Some types of hepatitis E virus are spread by drinking water contaminated by an infected persons stool. Other types are spread by eating undercooked pork or wild game. Related Conditions Diseases.
