Background: Acute hepatitis B is a reportable condition in
Objectives: To analyze the epidemiology of hepatitis B in
Methods: Local and regional health departments are notified by laboratories and/or providers about acute cases of hepatitis B. Health department staff then attempt to locate and interview the patient about symptoms, risk factors, and demographic information. The laboratory, clinical and other information is then entered into a computerized surveillance system. This information is electronically transmitted to the CDC for national surveillance purposes and can also be analyzed at the state or local level to assess disease trends.
Results: In 2008, the incidence rate of acute hepatitis B was 1.1 per 100,000 population, which reflects a case count of 562. There were an additional 8 cases of perinatal hepatitis B. The average age at diagnosis was 44 and cases were predominantly male (65.8%). For those with known race, 46.1% were white, non-Hispanic, 33.6% were Hispanic, and 17.2% were Black, non-Hispanic. Vaccine status was known for 19.8% of the cases and only 9.0% of those had received any hepatitis B vaccine.
Conclusions: Vaccination and other prevention efforts have decreased the incidence of acute hepatitis. However, progress can still be made in reducing the incidence of acute hepatitis B in
