What is hepatitis B?
Hepatitis B is a serious disease that affects the liver. It is caused by the hepatitis B virus (HBV). HBV can cause:
- Acute (short-term) illness. This can lead to:
- Loss of appetite
- Diarrhea and vomiting
- Jaundice (yellow skin or eyes)
- Pain in muscles, joints, and stomach
Acute illness is more common among adults. Children who become infected usually do not have acute illness.
Chronic (long-term) infection. Some people go on to develop chronic HBV infection. This can be very serious, and often leads to
- Acute (short-term) illness. This can lead to:
- liver damage (cirrhosis)
- liver cancer
- death
Chronic infection is more common among infants and children than among adults. People who are infected can spread HBV to others, even if they don’t appear sick.
Hepatitis B virus is spread through contact with the blood or other body fluids of an infected person. A person can become infected by:
- Acute (short-term) illness. This can lead to:
- contact with a mother’s blood and body fluids at the time of birth
- contact with blood and body fluids through breaks in the skin such as bites, cuts, or sores; – contact with objects that could have blood or body fluids on them such as toothbrushes or razors
- having unprotected sex with an infected person
- sharing needles when injecting drugs
- being stuck with a used needle on the job.
