Nipah Returns to West Bengal: 5 Infected, Over 100 Quarantined Near Kolkata
A fresh outbreak of the deadly Nipah virus in West Bengal has triggered a regional health alert, prompting airports across East Asia to reintroduce "Covid-style" screenings for travellers arriving from India. The outbreak, centered in the North 24 Parganas district near Kolkata, has so far infected at least five individuals, predominantly healthcare workers, and forced over 100 people into quarantine.
The alarm was raised earlier this week when five confirmed cases were reported from a private hospital in Barasat, a town approximately 25 kilometers from the state capital, Kolkata. The cluster of infections includes a doctor, nurses, and other hospital staff, sparking fears of hospital-acquired transmission.
State health officials report that the outbreak likely began with a patient who succumbed to severe symptoms before a diagnosis could be confirmed. Subsequent testing of those who treated the index patient revealed the spread. As of Tuesday, at least one of the infected nurses remains in critical condition. In a swift move to contain the virus, West Bengal health authorities have identified and quarantined approximately 110 contacts, including family members and colleagues of the infected staff.
The resurgence of the virus, the first in West Bengal in 19 years, has sent ripples of concern across neighbouring nations. Thailand, a major travel hub for the region, has aggressively stepped-up surveillance. Health authorities there have deployed thermal scanners and reintroduced health advisory cards at Suvarnabhumi, Don Mueang, and Phuket airports, specifically targeting passengers arriving from Kolkata. Travelers showing symptoms such as fever or respiratory distress are liable to be isolated for further testing.
"We are not taking any chances", a Thai health official was quoted as saying, emphasizing that while no cases have been detected in Thailand, the proximity and flight connectivity necessitate high vigilance.
Similarly, Nepal has intensified health checks at Tribhuvan International Airport in Kathmandu and at key land border crossings with India. Taiwan is also reportedly reviewing its travel alerts and moving to classify Nipah as a top-level notifiable disease, a designation that mandates immediate reporting and strict control measures.
The Nipah virus is classified by the World Health Organization (WHO) as a priority pathogen due to its epidemic potential and the lack of available vaccines or specific treatments. It is a zoonotic virus, naturally transmitted by fruit bats to animals like pigs, and subsequently to humans. Human-to-human transmission is also possible, particularly among caregivers. The virus is known for its high case fatality rate, which ranges from 40% to 75%.
India is no stranger to Nipah, having battled repeated outbreaks in the southern state of Kerala in recent years. However, the West Bengal strain has historically shown different transmission dynamics. The state last witnessed major outbreaks in 2001 and 2007 in the Siliguri and Nadia districts, which claimed dozens of lives.
As containment efforts continue in Barasat, the Union Health Ministry has dispatched a high-level central team to assist the state government. For now, the focus remains on contact tracing and isolation to prevent the cluster from spiralling into a wider epidemic.
