Pune, India, has reported 59 suspected cases of Guillain-Barré syndrome (GBS), an immunological nerve disorder. The sudden rise in cases has prompted the state health department to form a team to investigate. GBS is a rare condition that causes sudden numbness and muscle weakness.

Doctors have assured the public that GBS is not contagious and most patients recover fully with treatment.
