What is hepatitis B?
Hepatitis B is a contagious liver disease caused by the hepatitis B virus. When a person is first infected with the virus, he or she can develop an “acute” (short-term) infection. Acute hepatitis B refers to the first 6 months after someone is infected with the hepatitis B virus. This infection can range from a very mild illness with few or no symptoms to a serious condition requiring hospitalization. Some people are able to fight the infection and clear the virus.
For others, the infection remains and is “chronic,” or lifelong. Chronic hepatitis B refers to the infection when it remains active instead of getting better after 6 months. Over time, the infection can cause serious health problems, and even liver cancer.
What are the symptoms of hepatitis B disease?
Infants and young children usually show no symptoms. Hepatitis B infection causes
- Loss of appetite (not wanting to eat)
- Pain in muscles, joints, and stomach
- Nausea, diarrhea, and vomiting
- Dark urine
These symptoms usually appear 3 or 4 months after a person gets the virus.
Is it serious?
Hepatitis B can be very serious. Most people with a recent hepatitis B infection may feel sick for a few weeks to several months. Some people get over the illness. For other people, the virus infection remains active in their bodies for the rest of their life.
Although people with lifelong hepatitis B usually don’t have symptoms, the virus causes liver damage over time and could lead to liver cancer. There is no cure for hepatitis B, but treatment can help prevent serious problems.
Hepatitis B can cause liver damage and cancer. Mothers can unknowingly pass the disease to their babies at birth.
How does hepatitis B spread?
Hepatitis B is spread through contact with blood of an infected person (even if they show no symptoms).
- At birth
- Open cuts or sores
- Sharing toothbrushes or other personal items
- Food chewed for a baby
- Any infected family member or caregiver can pass the virus to your baby.
- The virus can live on objects for 7 days or more.
