Acute Hepatitis C Infections in the US by Transmission Method

"Health departments might conduct investigations of newly reported acute hepatitis C cases to ascertain risk behaviors and exposures associated with infection. However, investigations might not be possible for all cases if patients are lost to follow-up or if health departments lack adequate resources for investigating all cases reported in their jurisdiction.

"Among risk behaviors and exposures identified for reported cases of acute hepatitis C virus (HCV) infection in 2021, injection drug use was most commonly reported (57% of the 1,449 cases for which injection drug use information was available). HCV transmission associated with surgery, dialysis, or transfusion is extremely rare in the United States; thus, the reporting of these exposures might represent a history of recent receipt of these health care procedures and do not necessarily indicate these procedures were associated with HCV transmission."
