Hepatitis C Virus Infection Among Firefighters, Emergency Medical Technicians, and Paramedics — Selected Locations, United States, 1991-2000

First responders (e.g., firefighters, emergency medical technicians [EMTs], and paramedics) are at risk for occupational exposure to bloodborne pathogens. Recently, CDC has received inquiries from state and local health departments and occupational health services about the prevalence of hepatitis C virus (HCV) infection among first responders and the need for routine HCV testing among these workers. This report summarizes the findings of five studies of HCV infection among first responders. Although some of these workers may need HCV testing under certain circumstances, this report indicates that first responders are not at greater risk than the general population for HCV infection; therefore, routine HCV testing is not warranted. First responders should continue to follow standard precautions to reduce workplace exposure to bloodborne pathogens.

During November--December 1999, Home Access Health Corporation (Hoffman Estates, lllinois) [*] offered specimen collection kits (Hepatitis C [Check.sup.TM]) to 4400 active and retired members of the Philadelphia firefighters union. Respondents telephoned a toll-free number to receive their test results and to answer questions anonymously about nonoccupational risk factors for HCV infection. According to Home Access (R), serum was tested for antibody to HCV (anti-HCV) with an enzyme immunoassay (EIA 3.0; Ortho Diagnostic Systems, Inc., Raritan, New Jersey); repeatedly reactive samples were tested with a supplemental recombinant immunoblot assay (RIBATM 3.0, Chiron Corporation, Emeryville, California). In February 2000, Home Access reported that of 2146 respondents, 97 (4.5%) screened positive for anti-HCV
