Description
Human betaherpesvirus 7 (HHV-7) is one of nine known members of the Herpesviridae family that infects humans.
Both HHV-6B and HHV-7, as well as other viruses, can cause a skin condition in infants known as exanthema subitum, although HHV-7 causes the disease less frequently than HHV-6B. HHV-7 infection also leads to or is associated with a number of other symptoms, including acute febrile respiratory disease, fever, rash, vomiting, diarrhea, low lymphocyte counts, and febrile seizures,[8] though most often no symptoms present at all.
There are indications that HHV-7 can contribute to the development of drug-induced hypersensitivity syndrome, encephalopathy, hemiconvulsion-hemiplegia-epilepsy syndrome, hepatitis infection, postinfectious myeloradiculoneuropathy, pityriasis rosea, and the reactivation of HHV-4, leading to mononucleosis-like illness.
Complications with HHV-7 infection has been shown to be a factor in a great variety of transplant types.
