The marrow-suppressive effect of human herpesvirus-6 ranged from transient or self-limited bone marrow suppression to chronic or fatal aplastic anemia; bone marrow suppression was thought to be partially cytokine-mediated.
Human herpesvirus-6 resembles cytomegalovirus in its antiviral susceptibilities: It is resistant to acyclovir but susceptible to ganciclovir and foscarnet.

The discovery of human herpesvirus 6 (HHV-6) is a result of this pursuit.
HH-6 was isolated from interleukin-2–stimulated peripheral leukocytes of HIV and lymphoproliferative disorders.
Later, several strains of HHV-6 were isolated from the lymphocytes of children with exanthem subitum and patients with chronic fatigue syndrome and from the saliva of patients with HIV and healthy individuals.

 HHV-6 Testing
6 The variant detected is almost always variant B (>97%), which is different from other conditions such as MS where the variant detected is primarily variant A. Antibody tests are not as useful because they may take weeks to show a change in titer.
Since so many healthy individuals have detectable levels of latent virus in their white blood cells, PCR DNA tests of whole blood are not useful unless the test is quantitative, and the absolute level of virus can be compared to a healthy population.
