Acute Hepatitis B
A patient with an acute infection will test positive for the
hepatitis B virus (HBsAg), HBc-IgM, and possibly the HBe-antigen.
An acute hepatitis B infection follows
a relatively long incubation period — from 1 to 6 months
(with or without symptoms) and infected persons are able
to pass the virus to others at this stage;
Therefore, the screening and vaccination of close family/household
members and sexual partners is advised. Repeat blood tests
over a six-month period are needed to diagnose recovery or
chronic infection.
