摘　　要：目的在暗娼人群中开展新发感染检测,估算该人群的感染率和新发感染率,了解该人群艾滋病感染状况及流行趋势。方法对2011-2015年暗娼哨点采集的HIV-1确证阳性样本进行新发感染检测,计算感染率和新发感染率,用卡方检验进行统计学分析。结果 2011-2015年共对65 611例血样进行HIV-1抗体筛查,哨点阳性242例,新发感染50例,HIV-1感染率0.37%,新发感染率0.22%(95%CI:0.16-0.28)。卡方检验得到各年度新发感染率差异有统计学意义(=24.511,P<0.001)。结论 2011-2015年艾滋病在四川省暗娼人群中仍处于低流行态势,但仍需进一步加强针对暗娼人群的高质量行为干预和监测工作。Objective To estimate HIV - 1 incidence and recent infection and to understand the epidemic trends among female sex workers in Siehuan province by using assay in HIV/AIDS surveillance sentinel sites. Methods Specimens confirmed as HIV - 1 positive were tested with BED - CEIA. The annual HIV - 1 prevalence and incidence was calculated and adjusted by chi - square test. Results 65 611 serum specimens were collected and accepted HIV antibody screening. 242 of all were HIV - 1 positive, and 50 of them were identified as recent infections. The prevalence among FSW was O. 37% ,and incidence was 0.22 （95% CI：0.16 -0.28 ）. There was significant difference in year - specific HIC - 1 incidence E2 = 24. 511, P 〈 0.001 ）. Conclusion During 2011 -2015, the trend of HIV/AIDS among female sex workers is low, but enhancement of behavior intervention and surveillance on female sex workers is still required.
