Haley and Fischer1 in their study suggest that whereas injection-drug use commonly causes both occult anti–hepatitis C virus (HCV) seropositivity and the acute hepatitis syndrome, tattooing may commonly cause occult anti-HCV seropositivity, while rarely causing the acute hepatitis syndrome. They recommended that public policy on regulation and inspection of parlors should be determined by seroepidemiological studies rather than by the Sentinel Countries Study of acute hepatitis cases.
