Numbers and rates* of reported cases† of acute Hepatitis C virus infection, by state or jurisdiction — United States, 2017–2021
Source: CDC, National Notifiable Diseases Surveillance System.
* Rates per 100,000 population. Beginning in 2021, single-race population estimates are used for rate calculations. For prior years, bridged-race population estimates are used.
† Reported confirmed cases. For the case definition, see Acute Hepatitis C.
—: No reported cases. The reporting jurisdiction did not submit any cases to CDC.
N: Not reportable. The disease or condition was not reportable by law, statue, or regulation in the reporting jurisdiction.
U: Unavailable. The data were unavailable.
The capacity of each jurisdiction for notifying CDC of acute hepatitis C cases varies considerably on the basis of laws, resources, and infrastructure for conducting viral hepatitis surveillance. During 2021, acute hepatitis C was not a reportable condition in one state (Alaska), cases were unavailable from three states or jurisdictions (Arizona, District of Columbia, and Rhode Island), and no cases were reported by five states (Hawaii, Idaho, New Mexico, North Dakota, and Vermont).
The national rate of reported acute hepatitis C was 1.6 cases per 100,000 population during 2021, a 60% increase from the rate reported during 2017. During 2021, Maine had the highest rate of reported cases of acute hepatitis C (9.8 cases per 100,000 population), whereas Florida reported the largest number of cases (n = 1,545).
