Herpes Virus Type 7 DNA, PCR

It is now considered that both human herpesvirus 6 (HHV-6) and HHV-7 cause exanthem subitum (sudden onset of rash and fever which lasts several days and then suddenly subsides leaving in its wake a fine red rash). HHV-7 is also associated with the occurrence of febrile seizures and encephalitis / encephalopathy, and might invade and latently infect the CNS, or may be involved in CNS manifestations.

HHV-7 DNA could be detected in CSF obtained from exanthem subitum patients with CNS manifestations. Moreover, it has been found that primary HHV-7 infection is more likely to cause febrile seizures than primary HHV-6 infection. HHV-7 DNA could be detected in peripheral blood mononuclear cells (PBMC) of the majority of patients with CSF positive for HHV7 DNA.
