Wan started his career at China's Ministry of Health (MOH), working there in 1989 as a researcher. There, he translated the first announcement of the AIDS epidemic into Chinese. In 1992, he set up the first HIV/AIDS telephone hotline in China where people could obtain comprehensive information on HIV/AIDS. He was fired from his MOH job after founding AIZHI. Wan moved to Los Angeles after becoming a
Fulbright New Century Scholar. He returned to China in June 2002, and attempted to set up an independent medical clinic. In July 2002, Chinese authorities banned the AIZHI Action Project and shut down Wan's office. This occurred four days after the United Nations criticized China's inaction on HIV/AIDS. Detained by authorities and charged with the leaking of an internal government report, he was released a month later on 20 September like
ACT UP, who protested outside the Chinese consulate in New York City, and
Amnesty International. Upon his release told the BBC he learned a "good lesson". After his release on November 27, 2006, Wan accused Chinese leaders of falling "asleep" as the virus spreads. He was forced by the government to cancel his "Blood Safety, AIDS and Legal Human Rights Workshop," due to have taken place between 25 and 30 November 2006. == Other activism ==
