Hepatitis B (vaccine-preventable)

Factsheet

Hepatitis B (formerly known as serum hepatitis) is a liver disease caused by a virus. The disease is fairly common. 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. Childhood immunization is recommended.


Disease Reporting

What is required?

Health care providers and clinical laboratories are required by law to report cases and suspect cases of both acute and chronic Hepatitis B to local health departments within one working day of identification. Children in the communicable stages of Hepatitis B may be excluded from attending school or day care if, in the opinion of the local health officer, the child poses an unusually high risk to other children (e.g., exhibits uncontrollable biting or spitting). If sufficient measures have been taken to prevent transmission, or the disease is no longer communicable, worksite, child-care and school restrictions can be removed by the local public health authority.
