Transmission

Transmission of the hepatitis E virus generally happens when someone drinks water that is contaminated with the fecal matter—even just microscopic traces—of an infected person. Major outbreaks typically happen in regions of the world where sanitation is poor.

Few cases of hepatitis E have resulted from person-to-person contact, and there is no evidence that the virus can be spread through sexual activity. Transmission through blood is rare.
