The link between Kaposi's Sarcoma and HIV/AIDS was first noticed in the early 1980s. The weakened immune system in people with AIDS allows for the proliferation of the Human Herpesvirus 8 (HHV-8), also known as Kaposi's Sarcoma-associated Herpesvirus (KSHV). This virus is a key factor in the development of KS in these patients.
