Guillain-Barre Syndrome -- a rare nerve disorder -- that has affected 73 people in Pune is a life-threatening condition, said health experts on Saturday.

GBS is often followed by a bacterial or viral infection that wreaks havoc on the nerves. In people afflicted with GBS, the immune system mistakenly attacks healthy nerves outside the brain and spinal cord, leading to weakness and, sometimes, paralysis, or even death.
