Syphilis Infection among Entry-exit Personnel at Chengdu Port

[目的]进一步调查了解成都口岸出入境人群中梅毒的感染情况。[方法]对2004—2005年成都口岸出、入境人员进行血清学检测,首先使用梅毒螺旋体明胶颗粒凝集试验(TPPA)进行确认；然后进一步采用甲苯胺红不加热血清试验(TRUST)对被检者血清进行梅毒检测,对感染者进行流行病学调查并进行统计学分析。[结果]检测成都口岸出入境人员31780人次,查出梅毒感染者235人,检出率为0．74‰。其中男性检出率为0．85‰；女性检出率为0．18‰,二者间检出率进行比较差异有显著性。在各年龄组中,以60岁年龄组检出率最高为4．24％。[结论]在检测过程中TRUST和TPPA 2种检测方法同时使用,能够提高梅毒的检出率,避免漏诊,提示梅毒血清试验方法的选择和应用是及早、准确诊断潜伏梅毒重要手段。
