摘要对2011—2015年四川省9个市(州)艾滋病监测哨点的男男性行为人群(MSM)开展新发感染检测,估算该人群HIV?1的感染率和新发感染率.2011—2015年四川省MSM HIV?1新发感染率为5.16%(95%CI :4.65%～5.66%).根据《中国艾滋病流行水平分类标准(试行)》将9个市(州)分为一类(即报告现存活HIV/AIDS数占常住人口比例达到0.1%及以上,报告现存活HIV/AIDS数达到500例及以上)和二类(即报告现存活HIV/AIDS数占常住人口比例达到0.03%～0.100%,报告现存活HIV/AIDS数达到100～500例),二类地区新发感染率为4.24%(95%CI :3.72%～4.76%).四川省2011—2015年MSM HIV?1新发感染率较高,并存在疫情向二类地区蔓延的可能.

abstractsThe assay was used in HIV/AIDS surveillance sentinel sites to identify recent HIV?1 infection, to estimate HIV?1 incidence and understand the epidemic trends among men who have sex with men during 2011-2015.During 2011-2015, the HIV?1 incidence of men who have sex with men was 5.16%(95%CI: 4.65%-5.66%) in Sichuan Province. According to<Pilot study on classification criteria of AIDS epidemic in China>, a total of 9 cities had been divided into two type of regions: the first type(the proportion of live HIV/AIDS accounts for more than 0.1% of the permanent population, and the number of live HIV/AIDS has reached 500 cases and above) and the second type(the proportion of live HIV/AIDS accounts for 0.03% to 0.100% of the permanent population, and the number of live HIV/AIDS has reached 100-500 cases). During 2011-2015, the HIV?1 incidence of the second type was 4.24% (95%CI:3.72%-4.76%). The HIV?1 incidence of men who have sex with men was at a high level. The spread of HIV?1 to the second region was possible.
