 AB    Human immunodeficiency virus is an RNA virus in which the degree of
       genetic variation observed is phenomenal--up to 20% within an infected
       individual. This is essentially due to remorseless cycles of viral
       replication, most probably due to chronic activation of the immune
       system. It can be estimated that the number of variants in existence
       worldwide must be in excess of 10(14)-10(18), and given the nature of
       RNA viruses even more novel variants should emerge.
