The authors describe the epidemiologic and clinical characteristics of 97 human immunodeficiency virus (HIV)—infected patients, who were followed between 1993 and 2006. Seventy-two percent of the patients were male, and median age at diagnosis was 36 years (range, 13-71 years). The mean years of survival was 3, and maximum length of life after diagnosis was 9 years. The most common professions were truck drivers, workers, and housewives. Forty-six percent of the males had a history of working abroad. Heterosexual intercourse was the most common (84%) route of transmission. Seventy-four percent of the women acquired infection from their husbands. In Turkey, less educated or uneducated and poor men are the primary target of the HIV infection usually by sexual contact with foreign women. Considering the low education status of the patients, appropriate education programs should be developed to prevent the dissemination of HIV infection. Because a significant number of patients were diagnosed at very late stages, the physicians and other health care workers should be educated on the clinical pictures of HIV/AIDS.
