    Article - En anglais

    Study objectives

    To describe the prevalence of hepatitis B virus (HBV) infection in patients with sexually transmitted diseases (STD) and human immunodeficiency virus (HIV) infection, and to determine the role of sexual transmission of HBV infection in Singapore.


    A cross sectional study of all consecutive men presenting with a new episode ofSTD at a government outpatient clinic and all men with HIV infection on routine follow up at a government hospital.

    The prevalence of various HBV markers was compared with that of healthy males aged 15 years and above (controls).


    Singapore, a city state of intermediate HBV endemicity.


    These comprised 497 STD patients, 47 HIV infected patients, and 418 controls.

    Main results

    The overall seroprevalences of HBV infection in STD patients, HIV infected patients, and control subjects were 41.2%, 61.7%, and 33.3%, respectively (p<0.001).

    The seroprevalences of hepatitis B surface antigen (6.2%, 8.5%, and 4.5%, respectively) were comparable in the three groups.


    The importance of sexual transmission of HBV in an area of intermediate HBV endemicity was confirmed.

    Patients attending STD clinics should be routinely screened for HBV markers and those found to be seronegative should be strongly advised to be immunised against this virus.
