Detection of Herpesvirus-Like DNA Sequences in Kaposi's Sarcoma in Patients with and Those without HIV Infection

The same herpesvirus-like DNA sequences are present in AIDS-associated Kaposi's sarcoma, classic Kaposi's sarcoma, and the Kaposi's sarcoma that occurs in HIV-negative homosexual men. Therefore, this presumably new human herpesvirus is not solely an opportunistic infection in patients with AIDS, and the three forms of Kaposi's sarcoma may be caused by the same infectious agent.
