This document provides information about AIDS/HIV. It defines AIDS as a condition where the immune system is too weak to fight off infections, usually due to damage caused by the HIV virus. Some key points covered include: there is currently no cure for AIDS; it is estimated that over 25 million people have died from AIDS since 1981; antiretroviral treatment can suppress HIV and prevent AIDS but access to treatment is limited in some areas; and preventive measures include using only sterile needles, avoiding unnecessary blood transfusions, and HIV-positive women taking precautions to avoid pregnancy or spreading the virus.
