目的用BED-CEIA方法检测临沧市不同来源艾滋病监测样本中HIV-1新近感染,估算2011年的新近感染率。方法采用连续横断面调查方法,对2011年艾滋病不同来源监测样本中经过血清学检测确认为HIV-1抗体阳性的样本进行BED-CEIA检测,估算HIV-1新近感染率。结果采用BED-CEIA方法检测样本996份,发现HIV-1新近感染110例,感染率为0.27%,新近感染率为0.07(95%CI:0.04%-0.10%)。其中以自愿咨询检测者新近感染率最高,达到2.44%,其次为性病门诊就诊者和强制/劳教戒毒及其他羁押人员体检达到0.43%和0.21%。值得注意的是孕产期人群新近感染率也较高,达到0.13%。结论艾滋病自愿咨询检测者、性病门诊就诊者、感染者配偶及性伴为临沧市HIV新近感染较高人群,孕产妇新近感染率也不容忽视。
Objective To detect the recent HIV-1 infection in HIV monitoring samples from different sources in Lincang City by BED-CEIA method and estimate the recent infection rate in 2011. Methods A continuous cross-sectional study was performed to evaluate the recent HIV-1 infection rate by BED-CEIA in 2011 samples of HIV-1 positive samples from different sources of AIDS-related surveillance samples. Results A total of 996 samples were detected by the BED-CEIA method. It was found that 110 newly infected cases were infected with HIV-1, the infection rate was 0.27% and the recent infection rate was 0.07 (95% CI: 0.04% -0.10%). The most recent infection rate was 2.44% with voluntary counseling and testing, followed by 0.43% and 0.21% physical examination of STD clinic attendants and forced / re-education detoxification and other detainees. It is noteworthy that the newly infected rate of pregnant women is also higher, reaching 0.13%. Conclusions Voluntary counseling and testing of HIV / AIDS patients, STD clinics, spouses and partners of HIV infected persons are newly infected with HIV in Lincang City, and the recent infection rate of pregnant women should not be neglected.
