Central nervous system complications in human herpesvirus-6 infection
1Department of Pediatrics, Fujita Health University School of Medicine, Toyoake, Aichi, Japan.
Abstract:
Human herpesvirus-6 (HHV-6) is the causative agent of the common childhood infectious disease, exanthem subitum. After the virus was recently isolated from humans, it was found to be closely related to human cytomegalovirus (CMV), and was thus classified within the beta subgroup of human herpesviruses. HHV-6 possesses neurotropism in vitro, and it has been suggested that primary infection can cause complications of the central nervous system (CNS), including febrile seizures and encephalitis/encephalopathy. There is also speculation that the direct invasion of the virus into the CNS may play an important role in causing these neurological complications. Moreover, there are several reports which have suggested an association between HHV-6 and a variety of neurological disorders in adults. This paper will briefly review our virological understanding of the virus, and summarize recent findings regarding HHV-6 as an etiologic agent for CNS infection.
Insights
Human herpesvirus-6 (HHV-6), a common childhood virus, is linked to central nervous system (CNS) complications like febrile seizures and encephalitis. This review explores HHV-6
Area of Science:
- Virology
- Neuroscience
- Infectious Diseases
Background:
- Human herpesvirus-6 (HHV-6) causes exanthem subitum in children.
- HHV-6 is a beta-herpesvirus, related to human cytomegalovirus (CMV).
- HHV-6 exhibits neurotropism, suggesting a role in CNS complications.
Purpose of the Study:
- To review the virology of HHV-6.
- To summarize recent findings on HHV-6 as a cause of CNS infections.
- To explore the association between HHV-6 and neurological disorders.
Main Methods:
