What is the difference between ACUTE and CHRONIC infection?
Acute hepatitis B virus infection is a short-term illness that occurs within the first 6 months after someone is exposed to the hepatitis B virus; it is usually contracted by teenagers and adults with a full developed immune system. A person is diagnosed with chronic hepatitis B when they have the virus infection for longer than 6 months (confirmed through blood tests). It is usually contracted at birth or at a very young age when the bodys immune system is not fully developed.
