What is hepatitis E?
Hepatitis (hep-ah-TY-tiss) E is an inflammation of the liver caused by the hepatitis E virus, which is found in the stool of an infected person. There are several other very different “hepatitis” viruses that cause the same symptoms but are completely unrelated diseases. Hepatitis E rarely causes long-term liver damage or death but can cause very serious infection in pregnant women, especially during the third trimester (last three months of pregnancy). Hepatitis E is extremely rare in the United States and is almost always related to travel to a country where hepatitis E is common, e.g., Mexico, Africa, the Middle East, India, and China.
How is hepatitis E spread?
Hepatitis E virus is passed in the stool, and people become infected by having contact with the stool of an infected person (fecal-oral route). Most outbreaks have been associated with contaminated drinking water. For this reason, the virus is more easily spread in areas where there are poor sanitary conditions or where good personal hygiene is not observed.
Persons are at risk for hepatitis E infection if they have:
Casual contact, as in the usual workplace or school setting, does not spread the virus. However, most cases of hepatitis E have an unknown exposure, because the time from exposure to the time symptoms begin can be long (range of 15-64 days).
What are the symptoms of hepatitis E?
Symptoms usually occur suddenly. Some people, especially children, may have no symptoms but can still spread the virus to others.
Symptoms usually begin 26-42 days (range of 15-64 days) after exposure. Death from hepatitis E is rare but may be as high as 20 percent among pregnant women in their third trimester. Premature deliveries due to infection have a 33 percent infant mortality rate. People are most contagious from about 2 weeks before symptoms begin until 2 weeks after.
How do I know if I have hepatitis E?
A person having diarrhea lasting more than 24 hours or having jaundice should consult a health care provider immediately. The health care provider may collect a blood sample to test for hepatitis E.
How is hepatitis E treated?
There is no cure for hepatitis E. However, people who have had hepatitis E develop lifelong immunity to the virus. Unlike hepatitis A, there is no vaccine or immune globulin (Ig) to prevent infection.
How can hepatitis E be prevented?
