Summary
During 2022, the rates of reported acute hepatitis C ranged from a high of 6.8 cases per 100,000 population in Maine to a low of 0.1 or fewer cases per 100,000 population in Mississippi, Texas, and South Carolina. The largest absolute increase was observed in South Dakota from 0.4 cases per 100,000 population in 2021 to 1.8 cases per 100,000 in 2022. The largest absolute decrease was observed in Delaware, where the rate of 1.7 cases per 100,000 population in 2022 was a 71% decrease from the rate of 5.8 cases per 100,000 population in 2021. Because of the relatively smaller number of acute hepatitis C cases reported in certain jurisdictions, wide fluctuations in annual rates might occur.
