Only states with rates for 2020 and 2021 are shown. State/jurisdiction and year for no reported cases: Hawaii (2020, 2021), Idaho (2021), New Mexico (2021), North Dakota (2020, 2021), Vermont (2021), Wyoming (2020); for not reportable: Alaska (2020, 2021); for unavailable data: Arizona (2020, 2021), District of Columbia (2020, 2021), Rhode Island (2020, 2021).
State or jurisdiction ranked in decreasing order by the 2021 rate, 2020 rate, and then alphabetical order by name.

During 2021, the rates of reported acute hepatitis C ranged from a high of 9.8 cases per 100,000 population in Maine to a low of 0.1 or less cases per 100,000 population in South Carolina, Colorado, Kansas, Mississippi, and Texas. The largest absolute increase in rates was observed in Utah, with a rate during 2021 of 4.5 cases per 100,000 population, at increase of 41% compared to the rate in 2020 of 3.2 cases per 100,000 population. The largest absolute decrease was observed in Maine, where the rate of 9.8 cases per 100,000 population in 2021 was an 18% decrease from the rate of 11.9 cases per 100,000 population in 2020.  Because of the relatively smaller number of acute hepatitis C cases reported in certain jurisdictions, wide fluctuations in annual rates might occur.
