Source: CDC, Nationally Notifiable Diseases Surveillance System.
* Case reports with at least one of the following risk behavior/exposures reported 6 weeks to 6 months prior to symptom onset or documented seroconversion if asymptomatic: 1) injection drug use; 2) multiple sexual partners; 3) underwent surgery; 4) men who have sex with men; 5) sexual contact with suspected/confirmed hepatitis C case; 6) sustained a percutaneous injury; 7) household contact with suspected/confirmed hepatitis C case; 8) occupational exposure to blood; 9) dialysis; and 10) transfusion.  Reported cased may include more than one risk behavior/exposure.
† Risk behaviors/exposures data from one state was classified as ‘missing’ because of errors in reporting.

See Table 3.3 for more risk behavior/exposure data.

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 the 4,136 case reports of acute hepatitis C received by CDC for 2019, data regarding risk behaviors or exposures were missing for 1,873 (45.3%) cases. At least one risk behavior or exposure was reported for 1,626 (39.3%) cases during the 6-weeks to 6 months before illness onset. More than one risk can be reported for each case.
