What is the difference between an “acute” and a “chronic” hepatitis B infection?
A hepatitis B infection is considered to be “acute” during the first 6 months after being exposed. This is the average period of time it takes to recover from a hepatitis B infection. If you still test positive for the hepatitis B virus (HBsAg+) after 6 months, you are considered to have a “chronic” hepatitis B infection, which can last a lifetime.
