Abstract: The 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, 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.
