Transmission, symptoms and screening for hepatitis A, B and C

What are hepatitis A, B and C?

Hepatitis is a virus that attacks the liver. In most cases, no treatment is necessary. Hepatitis is usually eliminated by the body between 2 to 6 months depending on the type of virus. In doing so, the body produces antibodies that protect the individual for life. However, this is not the case for hepatitis C; healing does not protect against a new infection.

Some people with hepatitis B or C become long-term carriers. By attacking the liver, hepatitis B and C can cause chronic diseases (cirrhosis, cancer).
