For 2022, cases that meet the confirmed or probable case definitions for acute hepatitis C or newly reported chronic hepatitis C are summarized to show the total burden of cases reported by jurisdictions to CDC.

The ability of a jurisdiction to apply the case definitions varies (see Technical Notes). Cases of probable hepatitis C require a positive test for antibodies to hepatitis C virus (anti-HCV) in the absence of a hepatitis C virus ribonucleic acid (HCV RNA) test or other case definition criteria.

Therefore, it is unknown if cases classified as chronic probable hepatitis C represent current or resolved infections. Jurisdictions without a public health reporting law or mandate for the reporting of negative HCV RNA test results will classify a positive anti-HCV test result as a probable case of hepatitis C.

Jurisdictions with a public health reporting law or mandate for the reporting of negative HCV RNA test results will be more able to determine whether a positive anti-HCV test result is not a case (that is, evidence of prior infection), whereas jurisdictions without a public health reporting law or mandate for the reporting of negative HCV RNA test results may have higher number of hepatitis C cases characterized as chronic probable hepatitis C. For this reason, caution should be taken when comparing case counts for probable acute and chronic hepatitis C across jurisdictions.
