Hepatitis
B
Definition
The clinical case definition for all types of
viral hepatitis is: "An illness with discrete onset of
symptoms, and jaundice or elevated serum aminotransferase
levels." Laboratory confirmation of hepatitis B requires IgM
anti-HBc-positive (if done) or HBsAg-positive, and IgM anti-HAV-negative
(if done). Confirmed cases of acute hepatitis B must meet the
clinical case definition and be laboratory confirmed. Chronic
carriage or chronic hepatitis should not be reported as acute
hepatitis B. In
Maryland
, individuals with HBsAg positive laboratory results, but for whom
no clinical information is known, are not included in the reporting
of acute hepatitis B cases.
