Report Form [PDF - 6 pages] (February 2002)
The forms for reporting cases of viral hepatitis to CDC are currently being
revised. The new forms will be used to report cases of viral hepatitis through
the new National Electronic Disease Surveillance System (NEDSS). Drafts
of these forms are provided here for reference purposes, although use of
these forms nationally will only occur once NEDSS is operational.

Notes on sources and methodology:
a. Number of Acute Clinical Cases Reported:
For
Hepatitis A, Hepatitis B, and Hepatitis C/non-A, non-B hepatitis, the number
of cases reported to the National Notifiable Disease Surveillance System (NNDSS).
b. Estimated Number of Acute Clinical Cases and
New Infections:
Incidence estimates for Hepatitis A and Hepatitis B
are derived from catalytic modeling of seroprevalence data from the Third
National Health and Nutrition Examination Survey (NHANES III) applied to
cases reported to the Nationally Notifiable Disease Surveillance System
(NNDSS). Incidence estimates for Hepatitis C are derived by adjusting rates
from the Sentinel Counties Study of Viral Hepatitis (1982–2006) and Emerging
Infection Program (2007) for underreporting and asymptomatic infection.
c. Percent Ever Infected:
Seroprevalence estimates
for HAV, HBV and HCV come from the National Health and Nutrition Examination
Survey HAV: Bell BP, Kruszon-Moran D, Shapiro CN et al. Hepatitis A virus
infection in the United States: serologic results from the Third National
Health and Nutrition Examination Survey. Vaccine 23(2005):5798-5806.

of Hepatitis C virus infection in the United States, 1999 through 2002.
