According to the medical bulletin Viata Medicala, the number of young adults infected with AIDS in Romania has steeply increased during the past 10 years. Epidemiological data evidenced that the total number of AIDS cases in the 15-49 age group as of June 2000 was 761 compared to 37 cases in 1991. In this particular population, the disease transmission is likely to have occurred via unprotected sexual intercourse, since it is estimated that only 30% of sexually active women in Romania know about and use condoms. Apart from sexual transmission, the injection drug use is thought to be a secondary factor. In response, the health insurance system in Romania, although expensive, covered appropriate therapies including antiretroviral and HIV testing.
