*HCV, hepatitis C virus; RIBA, recombinant immunoblot assay; anti-HCV, antibodies against HCV; s:co, signal-to-cutoff. †A confirmed case requires laboratory confirmation. Laboratory criteria consist of at least 1 of the following: a positive result for a HCV RIBA, a positive result for a nucleic acid test for HCV RNA, an HCV genotype, or enzyme immunoassay with detection of anti-HCV and a s:co ratio predictive of a true positive result for a particular assay (see www.cdc.gov/ncphi/disss/nndss/casedef/hepatitisccurrent.htm for the 2005 Council of State and Territorial Epidemiologists/Centers for Disease Control and Prevention case definition). ‡Excludes New York, New York. §Cases could be reported with more than minimum laboratory criteria; totals add up to >100%. ¶Other sources of reports included private healthcare providers, facilities such as hospitals and outpatient clinics, and institutions such as prisons, blood banks, and drug treatment centers, among others.
