Hepatitis B is a serious liver infection
caused by the hepatitis B virus (HBV). A chronic hepatitis B
, which lasts more than six months, increases your risk of developing liver failure, liver cancer or cirrhosis, which is a condition that permanently creates scars of the liver.
A vaccine can prevent hepatitis B, but there's no cure
for it. If you're infected, taking certain precautions can help prevent spreading the virus to others.
Hepatitis B infection is caused by the hepatitis B virus (HBV)
which is passed from person to person through blood, semen or other body fluids, excluding sneezing or coughing. It can spread by:
- Sexual contact if you have unprotected sex with someone who is infected.
- Sharing of needles.
- Accidental needle sticks.
- Mother to child. However, the newborn can be vaccinated to avoid getting infected in almost all cases.
