Viral Hepatitis C, 2007

In 2007, 28 cases of symptomatic acute hepatitis C virus (HCV) infection were reported. In addition to the 28 cases, nine individuals with asymptomatic, laboratory-confirmed acute HCV infection were reported. Prior to 2006, both symptomatic and asymptomatic acute infections were counted as incident cases. This change in case counting criteria should be considered when examining case incidence trends.

Sixteen (57%) of the 28 case-patients resided in Greater Minnesota. The median age was 40 years (range, 19 to 61 years). Fifteen (54%) case-patients were female. Seventeen (61%) were white, three (11%) were American Indian, and three (11%) were black; race was unknown for five (18%) cases.

MDH attempts to ascertain risk factor information for the 6 months prior to onset of symptoms by collecting information reported by the case-patient to his/her health care provider and by interviewing the case-patient, if possible. A case-patient may report more than one risk factor, and may report different information to his/her health care provider than to MDH. Among the 28 case-patients, 11 (39%) used injection drugs; four (14%) had sexual contact with a known HCV-infected partner; two (7%) had multiple sexual partners; two (7%) had one sexual partner; one (4%) had sexual contact with an injection drug user; and one (4%) had an occupational exposure. No risk factor was identified for seven (25%) cases.

MDH received more than 2,000 reports of newly identified anti-HCV positive persons in 2007, the vast majority of whom are chronically infected. Because most cases are asymptomatic, medical providers are encouraged to consider each patient’s risk for HCV infection to determine the need for testing. Patients for whom testing is indicated include: persons with past or present injection drug use; recipients of transfusions or organ transplants before July 1992; recipients of clotting factor concentrates produced before 1987; persons on chronic hemodialysis; persons with persistently abnormal alanine aminotransferase levels; health care, emergency medical, and public safety workers after needle sticks, sharps, or mucosal exposures to HCV-positive blood; and children born to HCV-positive women. Infants born to HCV-infected mothers should be tested at 12 to 18 months of age, as earlier testing tends to reflect maternal antibody status. Persons who test positive for HCV should be screened for susceptibility to hepatitis A and B virus infections and immunized appropriately.
