Hepatitis B


What is hepatitis B?

Hepatitis B (formerly known as serum hepatitis) is a liver disease caused by a virus. The disease is fairly common; more than 2,000 cases are reported in New York State each year.


Who gets hepatitis B?

Anyone can get hepatitis B, but those at greater risk include:


How is the virus spread?

Hepatitis B virus can be found in the blood and, to a lesser extent, saliva, semen and other body fluids of an infected person. It is spread by direct contact with infected body fluids; usually by needle stick injury or sexual contact. Hepatitis B virus is not spread by casual contact.


What are the symptoms of hepatitis B?

The symptoms of hepatitis B include fatigue, poor appetite, fever, vomiting and occasionally joint pain, hives or rash. Urine may become darker in color, and then jaundice (a yellowing of the skin and whites of the eyes) may appear. Some individuals may experience few or no symptoms.


How soon do symptoms appear?

The symptoms may appear two to six months after exposure, but usually within three months.


For how long is a person able to spread the virus?

The virus can be found in blood and other body fluids several weeks before symptoms appear and generally persists for several months afterward. Approximately 10 percent of infected people may become long-term carriers of the virus.


What is the treatment for hepatitis B?

There are no special medicines or antibiotics that can be used to treat a person once the symptoms appear. Generally, bed rest is all that is needed.


What precautions should hepatitis B carriers take?

Hepatitis B carriers should follow standard hygienic practices to ensure that close contacts are not directly contaminated by his or her blood or other body fluids. Carriers must not share razors, toothbrushes or any other object that may become contaminated with blood. In addition, susceptible household members, particularly sexual partners, should be immunized with hepatitis B vaccine. It is important for carriers to inform their dentist and health care providers.


How can hepatitis B be prevented?

A vaccine to prevent hepatitis B has been available for several years. It is safe, effective and is recommended for people in high-risk settings who have not already been infected and infants who are born to mothers who are carrying the virus. It is also recommended that hepatitis B vaccine be universally administered to all children along with their routine childhood immunizations beginning at birth or two months of age. A special hepatitis B immune globulin is also available for people who are exposed to the virus. In the event of exposure to hepatitis B, consult a doctor or the local health department.
