* preliminary data.
** To date, acute hepatitis C cases reported in NETSS have been unreliable for monitoring the incidence of acute hepatitis C because: no serologic marker is available to diagnose acute hepatitis C, and anti-HCV positive persons may be reported as having acute hepatitis C without the necessary clinical information to confirm acute disease.
