In the wake of the severe acute respiratory syndrome, an increasing number of patients with neurological disorders, including Guillain-Barré syndrome (GBS), have been reported following this infection. The International GBS Outcome Study enrolling patients with GBS within 2 weeks from the onset of weakness. 49 patients with GBS were included. Patients with a confirmed or probable SARS-CoV-2 infection frequently had a sensorimotor variant 8/11 (73%) and facial palsy 7/11 (64%). The median time from the onset of infection to neurological symptoms was 16 days (interquartile range 12–22). Patients with SARS-CoV-2 infection shared uniform neurological features, similar to those previously described in other post-viral GBS patients. The frequency (22%) of a preceding SARS-CoV-2 infection in the study population was higher than estimates of the contemporaneous background prevalence of SARS-CoV-2, which may be a result of recruitment bias during the pandemic, but could also indicate that GBS may rarely follow a recent SARS-CoV-2 infection.
