Last month, a school teacher in the western Indian city of Pune found her six-year-old son upset about homework.
"I had erased some words and asked him to write them. I assumed he was angry and that's why he was not holding the pencil properly," she told the Indian Express newspaper.
She never imagined his struggle to hold a pencil was the first sign of Guillain-Barré Syndrome (GBS), a rare disorder where the immune system attacks nerve cells, causing muscle weakness and paralysis.
Within days, the boy was in intensive care, unable to move his arms or legs. As his condition worsened, he lost the ability to swallow, speak, and eventually breathe, requiring ventilator support. He is now recovering.
The boy is among around 160 reported cases of GBS since early January in Pune, an education and IT hub, ringed by industrial towns and villages. There have been five suspected deaths. Currently, 48 patients are in intensive care, 21 on ventilator, and 38 have been discharged, according to official figures.
