The discovery of the role of HHV8 in KS is a good example of how molecular and epidemiological approaches can work together to identify previously unknown infectious agents. Subsequent research has shown that HHV8 is associated with all variants of KS (AIDS KS, classic KS, endemic KS and iatrogenic KS) as well as with two rare lymphoproliferative diseases: primary effusion lymphoma (PEL) and the multicentric Castleman’s disease (MCD).
