Viral Hepatitis

Hepatitis C Virus Electron Microscopy 

Viral hepatitis is an infection that affects the liver. While there are at least six different types of hepatitis (A-G), the three most common types in the United States are hepatitis A, hepatitis B and hepatitis C.

Hepatitis A is an acute infection and people usually improve without treatment. Hepatitis B and hepatitis C can cause chronic, persistent infections, which can lead to chronic liver disease. There are vaccines to prevent hepatitis A and hepatitis B; however there is no vaccine for hepatitis C.
