Hepatitis D could be a rare kind of liver disease that solely happens in conjunction with viral hepatitis infection. The liver disease D virus can’t multiply while not the presence of viral hepatitis. It’s very uncommon in the United States.

Hepatitis E

Hepatitis E is a waterborne disease caused by the hepatitis E virus (HEV). Hepatitis E is principally found in areas with poor sanitation and usually results from ingesting feces that contaminates the installation. This disease is uncommon in the United States.
