Viral hepatitis is a term commonly used for diseases that produce similar signs and symptoms, but are caused by different viruses. At least five types of hepatitis viruses exist. The most common in the United States are hepatitis A, hepatitis B, and hepatitis C. Hepatitis D (delta) is an incomplete virus that requires the helper function of Hepatitis B to replicate. Hepatitis E is rare in the United States. Viral hepatitis can lead to major liver damage and even death. A person who has become infected with one type of hepatitis can, become infected with another type because the viruses are not the same. Blood tests are available to accurately diagnose each type of hepatitis. Hepatitis A and hepatitis B can be prevented by vaccination. Almost everyone is at some risk of getting viral hepatitis, but certain factors are associated with an increased risk. Are you, or someone you know, at risk?
