目的：了解南宁市公共场所从业人员梅毒感染情况及流行病学特征。方法收集南宁市公共场所从业人员12757例血液学样本,采用甲苯胺红不加热试验（TRUST）筛查梅毒,以梅毒螺旋体明胶凝集试验（TPPA）阳性确认梅毒感染人数的情况进行分析。结果12757研究对象的梅毒阳性人数253人,阳性率1．98％。用χ2检验进行组间的比较。其中男性4319人,阳性率2．92％,女性8438人,阳性率1．51％,梅毒感染阳性率在性别上有差异,具有统计学意义（χ2＝29．925,P ＜0．01）;分4个年龄段进行比较,17～＜30岁有9209人,阳性率0．90％;30～＜40岁有2480人,阳性率4．84％;40～＜50岁有890人,阳性率5．17％;50～＜70岁有178人,阳性率2．25％。各个年龄组间阳性率比较,差异具有统计学意义（χ^2＝205．996,P ＜0．01）。梅毒阳性率在40～49岁年龄段最高,30～39岁年龄段次之,17～29岁年龄段最低。结论40～49岁已成为梅毒感染的高危人群,应采取综合措施防控梅毒感染和传播。

Analysis on syphilis test results in 12 757 employees in public places
