OBJECTIVETo analyze the impact of efforts of community-based organizations (CBO) in HIV testing mobilization and case finding among men who have sex with men(MSM).

METHODSResults of HIV testing mobilization among MSM through CBOs in 15 program areas were collected and compared with corresponding HIV case reporting data to demonstrate the contribution of CBO-based HIV testing in HIV case finding among MSM from July 2008 to December 2011. Meanwhile,the proportion of screened HIV positives who received testing results notification,confirmatory test, following up and CD4 cell tests were analyzed and compared with those identified in medical institutions.

RESULTSA total of 196 075 HIV tests were performed for MSM, as a result of mobilization efforts of CBOs. Cumulatively 7704 new HIV cases were identified, accounting for 51.7% (7704/14 914) of all newly diagnosed HIV cases infected via homosexual sex in the program areas.Among the newly diagnosed MSM HIV infections in the program areas,the proportion of infections detected through the mobilization of CBOs increased from 35.4% (609/1722) in 2008 to 63.7% (2371/3722) in 2010, and 58.3% (3024/5189) in 2011. Compared with those identified through medical institutions, newly diagnosed MSM infections detected though CBOs testing mobilization have higher rates of receiving screening testing results notification (97.3% (4441/4563) vs 92.8% (13 140/14 153)) , (84.6% (2559/3024) vs 79.8% (5589/7002)) and CD4 cell tests (66.1% (1999/3024) vs 52.9% (3705/7002)), and a lower rate of receiving confirmatory test (78.6% (3588/4563) vs 85.6% (12 115/14 153)).

CONCLUSIONCBOs can take their advantages in mobilizing MSM to receive HIV test, and MSM HIV cases detected through CBOs have become the main source of MSM HIV case finding in program areas.
