WASHINGTON--New research presented at the 2nd National Conference
on Human Retroviruses and Related Infections appears to confirm
last year's report that a virus is the cause of Kaposi's sarcoma
(KS). Its discoverers, Drs. Patrick S. Moore and Yuan Chang of
Columbia University, are calling the virus Kaposi sarcoma-associated
The researchers announced that they have mapped the virus's basic
genetic structure and found that it is the largest known herpesvirus,
containing DNA made up of 270,000 nucleotide base pairs.
They have consistently found the genetic sequence for KSHV in
tissue samples from people with KS who are HIV negative. The virus
was noted in six samples from people with classic KS (usually
found in elderly Mediterranean men), four from HIV-negative gay
men, and 10 from Africans with endemic African KS.
