ABSTRACT

Objective To analyze the epidemic characteristics of HIV/AIDS among men who have sex with men (MSM) from 2006 to 2010 in China,and to provide evidence for the development of prevention and control measures.Methods Through the network reporting information system.The distribution of MSM transmission was analyzed.Through sentinel surveillance system from 2006 to 2010,data was gathered and analyzed for HIV/AIDS positive rates and condom use to describe the epidemic characteristics of HIWAIDS among MSM.Results Data from HIV/AIDS case reporting system showed that the proportion of MSM transmission was on the rise (from 1.5％ in 2006 to 10.8％ in 2010),becoming the fastest growth of spreading.Compared with other routes of spreading,MSM transmission showed the following obvious characteristics 15 to 29 years olds (54.6％),having higher culture background (senior high school graduattesed or above accounting for 69.8％),unmarried (64.8％),being cadres/teacher/doctor/retirees and students (accounted for 14.3％ and 7.9％),with high mobilityfloating population (36.2％),being urban population (72.6％),having history of blood donation without payment (26.7％ and 6.4％ ).In terms of location,they mainly lived in provinces as Beijing,Sichuan,Guangdong,Chongqing,Jiangsu,Zhejiang,Shanghai and Liaoning where economics were more developed.Data from HIV/AIDS sentinel surveillance system showed that,from 2006 to 2010,the HIV positive anti-body detection rate (median) was 3.4％ among MSM in this country,much higher than among the female sex workers.Rate on condom usage (median) was 73.2％,lower than among the female sex workers.Conclusion The proportion of HIV transmission among MSM was on the rapid rise from 2006 to 2010 in China.Through HIV/AIDS sentinel surveillance system,we found that the infection rate was high but the rate of condom usage was low among MSM.Factors as being 15 to 29 years olds,students and blood donors shold be under major concern.
