RT Journal Article SR Electronic T1 Hepatitis B virus markers in prostitutes in Singapore. JF Genitourinary Medicine JO Genitourin Med FD BMJ Publishing Group Ltd SP 127 OP 129 DO 10.1136/sti.61.2.127 VO 61 IS 2 A1 C L Goh A1 A Kamarudin A1 S H Chan A1 V S Rajan YR 1985 UL http://sti.bmj.com/content/61/2/127.abstract AB The prevalence of hepatitis B virus markers in 121 men and 239 women prostitutes was studied. Of 33 (9.7%) with hepatitis B surface antigen (HBsAg), nine (27.3%) also had hepatitis Be antigen, which was more prevalent in men than women. Antibodies to HBsAg (anti-HBs) and to hepatitis B core antigen (anti-HBc) were found in about 71% of men and women prostitutes. Hepatitis B virus markers were more prevalent in men than in women prostitutes. Compared with other people, prostitutes had a significantly greater prevalence of hepatitis B virus markers. This study strongly suggested the importance of sexual transmission of infection with hepatitis B virus in a country where infection is endemic.
