Abstract: Objective To explore TB/HIV knowledge awareness among community residents and find the problems existed in order to provide baseline information and scientific basis for in-depth research and development of intervention measures.  Methods A multi-stage random sampling method was used from June to July 2010, 669 cases of Shenzhen community residences aged 15 or above were enrolled, and information were collected through self-filling questionnaire.  Results 89.4% of the respondents had ever heard of HIV/AIDS and tuberculosis simultaneously, whereas only 38.7% of the respondents had heard of TB/HIV co-infection. Moreover, only 13.0% of the respondents had received TB/HIV co-infection knowledge. A large part of the residents didn’t know the interaction between HIV/AIDS and TB, and lacked the consciousness of AIDS and TB screening. Only 69.2% of respondents thought that TB/HIV co-infection could be prevented. In addition to poor awareness to some non-HIV transmission routes, HIV and TB transmission routes is well understood by respondents.  Conclusion At present, community residents lack of TB/HIV dual infection related knowledge. The health education on TB/HIV co-infection is imperative to community residents.
