To determine the incidence of sexually transmitted infections (STI) among decriminalised and regulated sex workers in Victoria.
The incidence of STI was calculated for individuals who attended the Melbourne Sexual Health Centre on more than one occasion. Results of initial screen specimens were not included. Follow up time was calculated in person months and used as the denominator with the number of "specified" STIs diagnosed over the study period as the numerator.
Among 388 sex workers the incidence of chlamydia, Trichomonas vaginalis, genital warts, and herpes was 0.61, 0.11, 0.79, and 0.17, respectively, per 100 person months of follow up. The mean number of sexual non-paying private partners in the past 3 months was significantly greater among those with chlamydia (0.8 v 1.5, p < 0.01) and any STI (0.7 v 1.2, p < 0.05).
The incidence of STIs was low among decriminalised and regulated sex work and most infections were related to partners outside of work. Frequent screening of sex workers will reduce the chance of workers passing on an STI but is expensive. However, it may also discourage women from joining the sex work system and push them into an illegal system with a worse outcome.
确定维多利亚州性交易合法化且受监管的性工作者中性传播感染（STI）的发病率。
计算多次前往墨尔本性健康中心就诊的个体的性传播感染发病率。初始筛查标本的结果未纳入计算。随访时间以人月计算，并用作分母，研究期间诊断出的“特定”性传播感染病例数用作分子。
在388名性工作者中，衣原体、阴道毛滴虫、尖锐湿疣和疱疹的发病率分别为每100人月随访0.61、0.11、0.79和0.17。在过去3个月中，患衣原体感染的人群（0.8对1.5，p<0.01）以及患有任何性传播感染的人群（0.7对1.2，p<0.05）中，无酬性伴侣的平均数量显著更多。
在性交易合法化且受监管的性工作中，性传播感染的发病率较低，且大多数感染与工作以外的性伴侣有关。对性工作者进行频繁筛查将降低其传播性传播感染的几率，但成本高昂。然而，这也可能会使女性不愿加入性工作体系，而被迫进入非法体系，导致更糟的结果。
