Hepatitis B Singapore | STD

Hepatitis B in Singapore: Hepatitis B is an infection of the liver caused by the Hepatitis B virus.

Hepatitis B infection is caused by the Hepatitis B virus and is usually screened for by detecting HBsAg in the blood. Immunity may be discerned by detecting HBsAb, and if absent, the Hepatitis B vaccine or Twinrix® vaccine may be given.





Hepatitis B virus (HBV) is a DNA Hepadna virus that causes an infection of the liver. Transmission is through blood or body fluids viz. mother-to-child transmission, sexual intercourse, transfusion of contaminated blood, and sharing of needles and syringes.

Sporadic infection occurs in people without apparent risk factors, in institutions for learning difficulties and also in children in countries of high endemicity, but in these cases the means of transmission is poorly understood.

A total of 65 cases of acute hepatitis B infections were reported in 2010. The overall age-standardised prevalence of HBsAg among Singapore residents aged 18 to 69 years decreased significantly from 4.0% in HBSS 1999 to 2.8% in HBSS 2005 (p = 0.002).
