 By 2010, 1888 surveillance sites had been established.Data from before the development of comprehensive surveillance suffered a number of shortcomings, including minimal coverage of the general population due to focus on high-risk groups, poor data on men who have sex with men (MSM), stovepiping among different government entities, and difficulties obtaining data from private healthcare providers.Through the early 2000s, the Chinese government limited discussion of data and statistics of HIV/AIDS in the country, and media only reported numbers approved by the government.
