What are the case definitions for reportable hepatitis B virus (HBV) infections?
Case definitions have been developed by CDC, in collaboration with the Council of State and Territorial Epidemiologists, to provide uniform clinical and laboratory-testing criteria for the identification and reporting of nationally notifiable infectious diseases. The case definitions for acute, chronic, and perinatal hepatitis B are available at the following links: Acute Hepatitis B Chronic Hepatitis B Perinatal Hepatitis B (Acquired in the United States or U.S. Territories) Additional guidance on viral hepatitis surveillance and case management is available at http://www.cdc.gov/hepatitis/SurveillanceGuidelines.htm.
