Neurological Complications of Zika virus infection

Guillain Barre Syndrome (GBS), a condition in which persons may present with acute onset of progressive paralysis. GBS should be reported to the Ministry of Health upon suspicion within 24 hours of presentation. All notifications received are subjected to an investigation.

Mortality associated with Guillain-Barre syndrome varies by sub-population.

Mortality may be higher in mechanically ventilated patients; in a review of GBS patients ventilated in the ICU between 1984 and 2007, 12% of patients died.
