Female sex workers (FSWs) are an important group of people vulnerable to sexually transmitted infections. Northern Brazil is a rural and socioeconomically underdeveloped region, with lack of epidemiological information on syphilis in key populations. This study investigated the prevalence and factors associated with exposure to among FSWs in three major cities in northern Brazil. This cross-sectional study was conducted with a convenience sample of 415 FSWs from the cities of Belém, Macapá, and Rio Branco. Blood samples and personal data were collected from January 2009 to August 2010. Rapid plasma reagin and immunoenzymatic assays were used to detect antibodies against . Logistic regression models were used to determine factors associated with exposure to . In total, 36.1% were exposed to , and 15.7% had active syphilis. Sexual risk behaviors, use of illicit drugs, low education, and reduced monthly income were associated with exposure to . The high rate of exposure to indicates the urgent need for measures to identify, treat, and prevent syphilis and an education program for the valuation, care, and social inclusion of FSWs in northern Brazil.
女性性工作者是易感染性传播感染的重要人群。巴西北部是一个农村且社会经济欠发达的地区，缺乏关键人群梅毒的流行病学信息。本研究调查了巴西北部三个主要城市女性性工作者中梅毒的流行情况及其暴露相关因素。本横断面研究采用便利抽样法，对来自贝伦、马卡帕和里奥布兰科市的415名女性性工作者进行了调查。于2009年1月至2010年8月期间采集血样和个人数据。采用快速血浆反应素试验和免疫酶法检测梅毒抗体。采用逻辑回归模型确定梅毒暴露相关因素。共有36.1%的人暴露于梅毒，15.7%的人患有活动性梅毒。性风险行为、使用非法药物、低教育水平和月收入减少与梅毒暴露相关。梅毒高暴露率表明迫切需要采取措施来识别、治疗和预防梅毒，并为巴西北部女性性工作者制定一个关于重视、关爱和社会融入的教育项目。
