Human Herpesvirus 6 (HHV-6) infects T-lymphocytes, and has been

identified as an etiologic agent of exanthema subitum. Rises in

antibody titers to HHV-6 have been detected during infection with

other  viruses. In seroepidemiology studies of the prevalence

of exposure using serum screening dilutions of 1:10, the detection

of IgG antibody in a mid-life population approaches 100%. Due to

this high prevalence of HHV-6 antibody, correlations of single IgG

titers with specific diseases are of little clinical value.


Evidence of acute infection or reactivation of HHV-6 is

demonstrated by a significant rise or seroconversion of IgG and

IgM titers.
