What is the main cause of hepatitis E?
HEV is usually spread by the fecal-oral route. In developing countries, where HEV genotypes 1 and 2 predominate, the most common source of HEV infection is contaminated drinking water. In developed countries, sporadic cases of HEV genotype 3 have occurred following consumption of uncooked/undercooked pork or deer meat.
Is hepatitis E RNA or DNA virus?
Hepatitis E virus (HEV) is a small quasi-enveloped, (+)-sense, single-stranded RNA virus belonging to the Hepeviridae family. There are at least 20 million HEV infections annually and 60,000 HEV-related deaths worldwide.
What type of virus is hepatitis E?
Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus (HEV); it is a type of viral hepatitis. Hepatitis E has mainly a fecal-oral transmission route that is similar to hepatitis A, although the viruses are unrelated.
How is hepatitis E diagnosis?
Definitive diagnosis of hepatitis E infection is usually based on the detection of specific anti-HEV immunoglobulin M (IgM) antibodies to the virus in a person’s blood; this is usually adequate in areas where the disease is common. Rapid tests are available for field use.
What happens if hepatitis is positive e?

What is the fastest way to cure hepatitis E?
There is no specific treatment capable of altering the course of acute hepatitis E. As the disease is usually self-limiting, hospitalization is generally not required. Most important is the avoidance of unnecessary medications.
