title: [Survey on recent infection of human immunodeficiency virus among men who have sex with men in Tianjin during 2008 - 2009].
abstract: OBJECTIVE
  To study the situation of HIV infections among men who have sex with men (MSM) in Tianjin during 2008 - 2009 and to provide reasonable evidence for intervention strategy.
  
  
  METHODS
  Transect investigations in MSM were conducted three times during 2008 - 2009. 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.
  
  
  RESULTS
  1799 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.
  
  
  CONCLUSIONS
  
  
  
  RESULTS
  of 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.
