[A survey on AIDS discrimination among medical college students].

OBJECTIVE: To understand the related knowledge, discrimination attitudes toward HIV/AIDS among medical college students, and to provide scientific evidence for further HIV/AIDS anti-discrimination intervention. METHODS: By means of stratified cluster sampling to classes, 2844 undergraduate students were randomly selected from medical colleges. A self-designed and self-administered questionnaire survey was conducted, and SPSS 13.0 software was used for data analysis. RESULTS: 2501 valid questionnaires had been collected. The overall HIV/AIDS knowledge coverage rate of the respondents was 73.1% (1828/2501); The HIV/AIDS discrimination rates in different questions were varying, the discrimination rate of infected with AIDS by bad sex and sharing needles was 83.1% (2078/2501) and 77.7% (1943/2501) respectively, the discrimination rates in term of contacting with HIV patients and their daily necessities, sharing desks, personal social were all exceeding 40%. CONCLUSION: The medical students held serious discrimination attitudes to HIV infected persons and patients; it is necessary to strengthen anti-discrimination education about HIV/AIDS among medical students.

[HIV-1 molecular epidemiological survey of drug users in Jiangxi province].

OBJECTIVE: To investigate HIV-1 molecular epidemiology of drug users in Jiangxi Province to analyze epidemic situation, subtype, origin of strain, and variation, and to provide information for prevention and control of AIDS. METHODS: Combining principles of traditional epidemiology and molecular epidemiology, the authors analyzed the epidemiologically related factors, the gene sequences and systematic mutation of HIV-1 gene in nine drug users in Jiangxi province. RESULTS: The HIV spread through the drug users in Jiangxi not only by injection but also by sexual contacts. The main epidemic strain found by sequence analysis was HIV-1 CRF01-AE that was closely related to the strain among drug users in Vietnam and Guangxi Zhuang Autonomous Region, with the average gene distance of 9.00 +/- 2.27 from the Vietnam strain. The origin of strain among drug users in the province was entirely the same. CONCLUSION: At present, HIV-1 CRF01-AE strain has spread in the whole province among the drug users. Vigorous behavioral interventions should be developed in drug users and un-safe sexual behavior population to prevent the epidemic.
