† Non-A, non-B hepatitis became a reportable disease in 1982.
§Numbers and rates shown for hepatitis C/ Non-A, non-B hepatitis were unreliable, reflecting the erroneous reporting of chronically infected persons as acute cases that occurred when testing for antibody to hepatitis C virus (anti-HCV) first became widely available.
¶ Excludes cases from New York City; data not available for 1985 - 1986. **Excludes cases from New Jersey and Missouri.
