ABSTRACT
OBJECTIVE@#To analyze the sexual behavior characteristics of the sexually transmitted HIV-positive people and to estimate the secondary transmission rate.
@*METHODS@#Field investigation and literature review were conducted among sexually transmitted HIV-positive people to collect general information during the last 6 months before notification of HIV infection. A mathematical model was used to estimate the secondary transmission rate.
@*RESULTS@#A total of 769 HIV-positive people were recruited for the study, 186 of them were women, 286 were men who have sex with women (MSW), 242 were men who have sex with men (MSM) and 55 were men who have sex with men and women (MSMW). During 6 months, the average sex partner among these 4 groups were 2.29, 1.61, 3.32 and 4.10, respectively; the sexual behavior frequency were 26.03, 20.97, 14.77 and 25.51, respectively; the rates of non-use of condom were 74.14%, 73.53%, 59.60% and 72.06%, respectively; the secondary transmission rate were 0.0095, 0.0151, 0.1759 and 0.1985, respectively. Under constant conditions of other factors, the secondary transmission rates decreased by 30.13%-82.00%, 23.00%-49.51%, and 16.10%-19.09%, respectively, if there was a reduction in 1 sex partner, 1 time/month for the sexual frequency and 20% of rate for non-use of condom.
@*CONCLUSION@#The HIV secondary transmission from MSMW HIV-positive people to general population was the highest. Change in sexual behavior of the HIV-positive people can decrease the HIV secondary transmission rate significantly.
