​Infectious Diseases and Microbiology - Hepatitis E ( Hepatitis E Virus) 
The hepatitis E virus (HEV) is a calicivirus that causes hepatitis E. Sewage-contaminated drinking water is a common vector for the transmission of HEV, which occurs via the fecal-oral pathway. Acute hepatitis in underdeveloped nations is mostly caused by a lack of proper sanitation, and HEV is present everywhere. People in industrialized countries who have recently traveled to locations where HEV infection is common are more likely to have clinical hepatitis E.

The symptoms of hepatitis E are similar to those of other types of acute viral hepatitis, including lethargy, nausea, vomiting, pain in the upper right quadrant, dark urine, jaundice, and exhaustion. Particularly dangerous for pregnant women in their third trimester, HEV infections can cause fulminant hepatitis.

HAV and HEV pathophysiology are comparable. When infected with HEV, a chronic infection or carrier status is not established.
The presence of an IgM or IgG antibody specific to HEV allows for a laboratory diagnosis of the virus.

Hepatitis E virus (HEV) vaccines and treatments are inconclusive. Lower transmission rates would be achieved by using improved sanitary conditions, such as boiling drinking prevention water.
