Bulgaria marks World AIDS Day with a number of initiatives. World AIDS Day has been held since 1988 on the initiative of the World Health Organization. It aims to raise awareness of the Aids pandemic caused by the HIV infection and adress the HIV-related stigma.

From 1986 until November 24, 2023, a total of 4,276 people with HIV infection have been registered in the country.
