摘要:People with HIV have always faced stigma and discrimination. Given the numerous papers that have addressed the psychological and social risk factors in spreading HIV, a pressing question is whether individuals’ mere careless and behavioural flaws can still account for the spread of HIV. Barriers and opposing politic made a hard position for HIV and sex education in Iran. The present study investigated the causes of contracting HIV/AIDS from the perspective of HIV-infected patients. To accomplish this, 150 patients referring to the voluntary counseling and testing Center, Shiraz were convenient selected based on the convenient sampling method and responded to a researcher-made questionnaire From June to August 2019. The data were analyzed through descriptive statistics (mean, SD, frequency tables) and inferential statistics (chi-square). Results revealed that the main cause of HIV infection amongst males was the injection of narcotics, and in the females it was sexual intercourse with an infected individual. Meanwhile, 57% of the females and 66% of the males blamed themselves for contracting and transmitting the disease. The patients stated that if they could return to pre-infection period, they would use one of the following ways to prevent the disease: (a) they would pay attention to hygienic/sanitary principles; (b) they would not get married; and (c) they would prevent drug addiction. Also only 44% of the individuals had successful siblings (those who were neither addicts nor HIV/AIDS-infected individuals), which was an observation that emphasizes on the epidemic of high-risk behaviors in the patients’ families. According to participants' statements collected in our study, weakness in governmental public health education, along with family-related and individual factors, are important causes of HIV spread.
