**Pune, India –** A cluster of 67 Guillain-Barré Syndrome (GBS) cases, 13 requiring ventilator support, has prompted a major investigation in Pune. The Pune Municipal Corporation (PMC) is focusing on the Sinhagad Road area, between Rajaram Bridge and Khadakwasla, where the majority of cases have been reported.

Water samples from 30 localities within this area have been collected and tested. Preliminary reports show turbidity and chlorine presence in the water, but tests for GBS-causing bacteria have so far been negative. However, the Municipal Commissioner, Rajendra Bhosale, stated that a need for treated water in the affected areas is evident. The aging water supply network is suspected to be a contributing factor, and the PMC is planning a ₹408 crore (approximately $49 million USD) project to revamp the system and ensure treated water for all residents.

While the cause remains under investigation, experts suggest a possible link to norovirus, a common cause of gastroenteritis spread through contaminated food or water. Health authorities are monitoring the situation closely and treating patients, who are currently reported to be stable. Further investigation into the biological content of the water samples is pending.
