Hepatitis B is a virus that spreads through contact with body fluids and blood, so it can be transmitted through sexual intercourse. Infection is also possible through sharing of needles, razors, and toothbrushes. Babies can become infected at birth from an infected mother. Symptoms of hepatitis B infection include nausea, abdominal pain, and jaundice (yellowing of the skin and whites of the eyes). Over time, scarring of the liver (cirrhosis) and liver cancer can develop. It’s possible to go for years without symptoms of the infection.
Although there is no cure, there is a vaccine to prevent hepatitis B infection.
