Taxonomy

In 1992 the two variants were recognised within Human herpesvirus 6 on the basis of differing restriction endonuclease cleavages, monoclonal antibody reactions,[2] and growth patterns.[3] In 2012 these two variants were officially recognised as distinct species by the International Committee on Taxonomy of Viruses and named Human betaherpesvirus 6A and Human betaherpesvirus 6B.[4] Despite now being recognised as paraphyletic, the name Human herpesvirus 6 still sees usage in clinical contexts.

Pathology
See also: Human herpesvirus 6

Human betaherpesvirus 6A affects humans and includes several adult-derived strains. Its disease spectrum is not well defined, although it is thought by some to be more neurovirulent than Human betaherpesvirus 6B.[5][6]
