Abstract:
Facial nerve palsy has long been considered to have an infectious etiology, either viruses, mainly herpesviruses, or bacteria, such as Borrelia burgdorferi. We report for the first time the association of human herpesvirus 6 and facial palsy in a previously healthy 1-year 9-month-old boy who developed left facial nerve palsy 7 days after exanthema subitum caused by human herpesvirus 6.
Insights
Human herpesvirus 6 (HHV-6) is newly associated with facial palsy in children. This finding links HHV-6 infection to a specific neurological complication in young patients.
Area of Science:
- Virology
- Neurology
- Pediatrics
Background:
- Facial nerve palsy is often linked to infections, primarily herpesviruses or Borrelia burgdorferi.
- Herpesviruses are a common suspected cause of facial nerve palsy.
Observation:
- A previously healthy 1-year, 9-month-old boy presented with left-sided facial nerve palsy.
- The palsy developed seven days after exhibiting symptoms of exanthema subitum.
Findings:
- The exanthema subitum was confirmed to be caused by human herpesvirus 6 (HHV-6).
- This case represents the first reported association between HHV-6 infection and facial palsy.
Implications:
- This finding expands the known spectrum of neurological complications associated with HHV-6.
- Further research is warranted to understand the mechanisms linking HHV-6 to facial nerve palsy.
