Pune: The Pune Municipal Corporation (PMC) has officially declared that the recent outbreak of Guillain-Barré Syndrome (GBS), which primarily affected the Sinhagad Road area, is now under control. According to health officials, no new cases have been reported since February 18, prompting the department to seek formal confirmation from the Deputy Director of Health.
The outbreak first surfaced in January 2024, raising serious health concerns among residents and authorities. Investigations identified the Sinhagad Road locality as the epicenter, with contaminated food and water believed to be the primary sources of infection.
GBS is a rare neurological disorder in which the body’s immune system mistakenly attacks the nerves, leading to muscle weakness, paralysis, and, in severe cases, respiratory complications. Given the potential severity of the condition, authorities acted swiftly to contain its spread.
In response to the outbreak, PMC deployed medical teams to conduct door-to-door screenings, checking residents for symptoms. Water samples were collected and analyzed to determine contamination levels.
The National Institute of Virology (NIV) and state laboratories identified Campylobacter jejuni bacteria and Norovirus as the leading causes of the outbreak. These pathogens are known to spread through contaminated water and food, reinforcing the need for strict hygiene measures.
To curb further transmission, the health department intensified surveillance efforts, ensured the distribution of clean drinking water, and launched public awareness campaigns. Local hospitals were also instructed to monitor and promptly report any new cases with symptoms such as fatigue, diarrhea, and vomiting.
A large-scale investigation into water contamination revealed several concerns:
Total samples tested from Parvati Water Purification Center: 3,735
Tanker water found unfit for consumption: 15
Contaminated RO plants identified: 39
Water samples sent to NIV for testing: 214
Samples confirmed to be contaminated: 6
Samples tested at the State Laboratory: 80
These findings underscored the urgent need for stringent water quality monitoring to prevent future outbreaks.
With no new infections recorded for over a month, health officials are confident that the outbreak has been contained. Since the incubation period for Campylobacter jejuni and Norovirus ranges between three to five days, the absence of fresh cases suggests that the risk has significantly declined.
Despite the improvement, authorities remain vigilant. Regular water quality tests will continue, and outpatient departments (OPDs) at hospitals will closely monitor cases of diarrhea, vomiting, and unexplained fatigue to prevent any resurgence.
