RNA virus belonging to the family Flaviviridae, genus Flavivirus. Lauer and Walker reported that HCV is closely related to hepatitis G, dengue, and yellow fever viruses. HCV can produce at least 10 trillion new viral particles each day. The HCV genome consists of a single, open reading frame and two untranslated, highly conserved regions, 5′-UTR and 3′-UTR, at both ends of the genome. The natural targets of HCV are hepatocytes and, possibly, B lymphocytes.

Arabic numerals denote the genotype, and lower-case letters denote the subtypes for lesser homology within each genotype.

Within a region, a specific genotype may also be associated with a specific mode of transmission, such as genotype 3 among persons in Scotland who abuse injection drugs. Since 1992, however, the screening of donated blood for HCV antibody sharply reduced the risk of transfusion-associated HCV infection. Persons who inject illicit drugs with nonsterile needles are at the highest risk for HCV infection.
Transmission of HCV to healthcare workers may occur via needle-stick injuries or other occupational exposures. According to Rischitelli et al, however, the prevalence of HCV infection among healthcare workers is similar to that of the general population. HCV may be transmitted via sexual transmission. However, studies of heterosexual couples with discordant serostatus have shown that such transmission is extremely inefficient. HCV may also be transmitted via tattooing, sharing razors, and acupuncture. The use of disposable needles for acupuncture, now the standard practice in the United States, should eliminate this transmission route. Breastfeeding is not associated with transmission. Casual household contact and contact with the saliva of those infected are inefficient modes of transmission.
HCV is the major cause of chronic hepatitis in the United States. The overall prevalence of anti-HCV antibodies in the United States is 1. HCV RNA, meaning that active viral replication continues to occur. 9 million persons are infected with HCV and 2. 7 million persons in the United States have chronic infection. Alter et al reported that HCV infections account for approximately 30,000 new infections and 8,000-10,000 deaths each year in the United States.
