"Human immunodeficiency virus (HIV) poses a medical, social, and economic problem. In Romania since 2002, the prevention of HIV transmission and the care for HIV-positive people have been overseen by Governmental Law. HIV infection in Romania has some particularities, such as the high number of HIVinfected patients under treatment and the high percentage of long-term survivors. Romania reported its first case of AIDS to the World Health Organization in 1985, and its first case in the pediatric population in 1989. A year later, a new case definition, based on local possibilities was formulated together with the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC, Atlanta, GA). According to the latest report of the Compartment for Monitoring and Evaluation of HIV/AIDS in Romania, the cumulative number of HIV cases registered between 1985-2021 was 26,171, while the number of people living with HIV at the end of December 2021 was 17,271.
