The purpose of this study was to examine AIDS-related knowledge and attitudes of the Taiwanese community in Sydney and to provide the information of AIDS health promotion programs so as to meet their needs. The convenient sample consisted of 80 Taiwanese migrants. The data was obtained from self-administered questionnaire survey and was analysed by using SPSS program. The percentage of correct answers for all respondents was 80%, with a mean score of 11.2. Surprisingly, 70% of respondents thought that HIV/AIDS could be transmitted by a mosquito bite. Males had a significantly better HIV/AIDS-related knowledge than females did. The survey also highlighted the uneven nature of attitudes towards those with HIV/AIDS. Three-quarters of respondents did not think that HIV/AIDS is a punishment for immorality. Conversely, the majority of respondents disallowed doctors having HIV/AIDS to go on their practice and refused HIV infected person handling food in restaurants. Males had more positive attitudes towards HIV infected person than females did. In conclusion, a person with sufficient knowledge regarding AIDS is not necessary to be in favor of HIV/AIDS persons. Thus, public health workers should emphasize on not only improving the public's knowledge about AIDS but also their attitudes towards HIV infected persons.
