    • Description:
      Issued September 2000.

      With this issue, we are introducing a revised format for our description of surveillance data, which focuses on presentation of data with figure and tables and limited text. We invite readers to send us comments (see Preface for address). A copy of this report is available on the CDC Internet site at http://www.cdc.gov/hepatitis.

      This report summarizes surveillance data collected during 1994-1995 for acute viral hepatitis. With a total of 46,963 cases reported to CDC in 1995, acute viral hepatitis was exceeded only by AIDS (71,547 cases), chlamydia (477,638 cases), gonorrhea (392,848 cases), and syphilis (68,953 cases) among reportable diseases in the United States. After declining from 1989-1993, the overall case count has increased from 1994-1995 as a result of a cyclic increase in hepatitis A. In 1995, a total of 31,582 cases of hepatitis A were reported, which was the highest yearly total since 1989. Hepatitis B has declined steadily since 1985.

      The objective of national surveillance of acute viral hepatitis is to provide serologic, demographic, and epidemiologic information that will aid in formulating strategies and policies for the prevention and control of these diseases. The hepatitis surveillance report interprets and disseminates this information, presents new developments in the field, and clarifies issues related to viral hepatitis.

      Nationwide information on hepatitis is obtained by two surveillance systems. In one, incidence data are collected from cases reported to the CDC National Notifiable Diseases Surveillance System (NNDSS) by each state and territory. The etiologic classification is made by physician diagnosis; confir- mation by serologic testing is not required. The number of cases and date reported of hepatitis A, hepatitis B and hepatitis C/non-A, non-B appear in the Morbidity and Mortality Weekly Report (MMWR) and the MMWR Annual Summary of Notifiable Diseases, and are summarized in this report as well.

      In the other system, clinical, serologic and epidemiologic data pertaining to risk factors for disease acquisition are obtained from the Viral Hepatitis Surveillance Program (VHSP), a separate reporting system operated by the Hepatitis Branch, Division of Viral and Rickettsial Diseases, National Center for Infectious Diseases, CDC, Atlanta, Georgia. The VHSP obtains its information from the viral hepatitis case record, a copy of which appears in the Appendix. This form (CDC 53.1) can be obtained from the Hepatitis Branch. In addition, in 1991 several states began submitting their case reports via electronic surveillance through the National Electronic Telecommunications System for Surveillance (NETSS). By 1995, 67% of VHSP cases were submit- ted electronically. For states interested in using NETSS to report hepatitis case investigations (core data plus extended record for serologic and risk factor data), the Hepatitis Branch and CDC’s Epidemiology Program Office will provide technical support.

      A third surveillance system referenced in this report is the Sentinel Counties Study of Acute Viral Hepatitis, a more intensive study of viral hepatitis in six counties representative of the United States as a whole. This surveillance system has provided nationally representative data on acute viral hepati- tis since 1982, and has been a resource for detecting emerging infections and performing more in-depth studies. Data from the Sentinel Counties have been included for comparison with the other surveillance systems in this issue.
