Summary
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 2022, acute hepatitis C was not a reportable condition in one state (Alaska), cases were unavailable from one state (Arizona), and no cases were reported by two states (Hawaii and North Dakota).
The national rate of reported acute hepatitis C was 1.5 cases per 100,000 population during 2022, a decrease of over 6% from the rate during 2021. During 2022, Maine had the highest rate of reported cases of acute hepatitis C (6.8 cases per 100,000 population). Florida reported the largest number of cases (n = 1,463) — 30% of all reported acute hepatitis C cases during 2022.
