About Hepatitis B (unspecified)
Hepatitis B is a viral infection of the liver.
Some people will recover within 6 months as their body clears the virus without treatment.
But most people who get infected will develop chronic hepatitis B, where the infection lasts for more than 6 months.
People infected as babies or young children often develop chronic infection.
After many years, chronic hepatitis B can damage the liver and cause serious disease, including primary liver cancer.
Most people don’t get symptoms until the liver is damaged, so testing people who could have hepatitis B is important.
