Transmission is by blood and body fluid contamination, sexual transmission, and from mother to baby at the time of birth (vertical transmission). Confirmation of the diagnosis is by detection of HBsAg, but assessment of severity, prognosis and indication for treatment requires quantification of HBV DNA in serum.
