Core Tip

Core Tip: Hepatitis E is a common viral infection that has been increasing in developed nations. It usually causes a self-resolving acute hepatitis. It can sometimes lead to chronic hepatitis, and even cirrhosis/hepatic failure. Several subtypes exist, however the types responsible for infections in humans are generally spread via pork consumption or contaminated water. Treatment is usually supportive, however, ribavirin has shown efficacy in those with severe or chronic infection. Immunocompromised and pregnant patients should be evaluated with particular caution. Vaccination is currently licensed in China, and many studies are underway assessing vaccination efficacy in other nations as well.
