Two healthcare workers in Barasat city, North 24 Parganas, West Bengal, are suspected of Nipah virus infection. They were detected at AIIMS-Kalyani in Nadia district on Sunday night. Both are currently receiving treatment and are under observation. "Patients are under treatment and observation. Contact-tracing and treatment plans have already been made," said West Bengal Chief Secretary Nandini Chakraborty. The names of the patients’ hospital have not been disclosed. Ms. Chakraborty urged people to stay calm, avoid spreading misinformation, and follow hygiene rules. The State government also launched three helpline numbers for public queries: 03323330180, 9874708858, and 9836046212. The two patients had recently traveled to Purba Bardhaman for personal work. Contact tracing is ongoing in North 24 Parganas, Purba Bardhaman, and Nadia districts. Officials said the patients have not left West Bengal recently and are in touch with their families. The Union Health Ministry has sent a joint outbreak response team with experts from AIIMS-Kalyani, National Institute of Virology Pune, and other centers to support the state. A senior Health Ministry official stated, "Given the serious nature of Nipah virus infection, which is a zoonotic disease with high mortality and potential for rapid spread, the situation is being handled with utmost priority." Union Health Minister J.P. Nadda has assured full support to West Bengal’s government. The Central government is providing technical, logistical, and laboratory assistance and advising strict infection control and surveillance. Chief Minister Mamata Banerjee visited the hospital late Sunday night. Nipah virus, a bat-borne disease, shows symptoms like fever, muscle pain, sore throat, and breathing trouble, with severe cases causing convulsions and respiratory distress. Experts stress extensive contact tracing as some patients may carry the virus without symptoms. Dr. Subarna Goswami advised avoiding raw date palm sap, a possible infection source, and recommended boiled or processed jaggery instead. No vaccine is currently available, but patients receive isolation and supportive care. The last Nipah outbreak in West Bengal was in 2007; the recent one in India was in Kerala, August 2025.
