Q

Etiology of Guillian Barré Syndrome

  • Causative agents
A

It occurs 2 - 4 weeks after a benign febrile illness:

  • 2/3 of cases follow a respiratory or gastrointestinal infection
  • Campylobacter infection 20 - 30%
  • Others e.g. CMV, EBV, HSV

GBS has been reported to follow:

  • Vaccinations
  • Epidural anesthesia
