Guillain-Barré syndrome has been reported with varying severity in nineteen COVID-19 patients so far. The presented symptoms, which typically occurred approx. one week after the onset of respiratory symptoms, were facial weakness, difficulty breathing, inability to stand or walk, and difficulty weaning off respiratory ventilators. Scientists are unsure whether Guillain-Barré syndrome stems directly from COVID-19, possibly as a result of molecular mimicry, or whether it results from unrelated neurological problems.
