Fri Jan 24 22:10:04 IST 2025: ## Pune Grapples with Guillain-Barré Syndrome Outbreak Linked to Norovirus and Campylobacter

**Pune, India** – A cluster of over 60 cases of Guillain-Barré Syndrome (GBS), a rare neurological disorder, has prompted a health alert in Pune. Preliminary investigations by the Indian Council of Medical Research–National Institute of Virology (ICMR-NIV) have identified norovirus and Campylobacter bacteria in some affected individuals.

While both pathogens are common causes of gastrointestinal illness, their presence raises concerns about a potential link to the GBS outbreak. Norovirus, currently surging in the West, causes vomiting and diarrhea, while Campylobacter jejuni infection leads to bloody diarrhea, abdominal pain, and fever. The Neurological Society of Pune has urged the public not to panic, emphasizing that GBS is treatable.

GBS is an autoimmune disorder where the body’s immune system attacks the peripheral nervous system, causing weakness, fatigue, and pain. In severe cases, it can lead to paralysis and respiratory difficulties, requiring immediate medical attention and potentially life-saving treatments such as intravenous immunoglobulin or plasma exchange. While there is no cure, many patients recover, although recovery times can vary widely. Doctors stress that although a viral or bacterial infection often precedes GBS, the exact cause remains unknown.

Health officials are investigating the source of the outbreak and urging residents to practice good hygiene to prevent the spread of gastrointestinal infections. Anyone experiencing symptoms such as weakness, numbness, or difficulty breathing should seek immediate medical attention.
