Blood samples were collected and detected to identify the recent HIV infection with IgG-capture BED-enzyme immunoassay (BED-CEIA) before HIV incidence was estimated.RESULTS1799 specimens were tested and the HIV prevalence rates of each study were 6.7%, 8.6% and 6.2%, while the incidence rates were 2.7%, 2.5% and 2.8%, respectively. The estimated incidence rates among these testees were 5.36% and 5.52% per year in 2008 and 2009.CONCLUSIONRESULTSof this study showed that the HIV incidence stabilized at high level among MSM in Tianjin, calling for the effective interventions be taken for HIV/AIDS control and prevention.
