West Bengal reports two Nipah infections among nurses near Kolkata; surveillance and quarantine stepped up

What officials say happened

Health authorities in India have confirmed two Nipah virus cases in West Bengal involving two nurses at a private hospital near Kolkata. One of the nurses has been reported to be in critical condition. Officials indicated that an initial investigation suggests exposure linked to a patient with severe respiratory symptoms who died before being tested, and who is being treated as a suspected index case.

In response, public health teams initiated testing, quarantine and surveillance measures. As of 20 January, reports said 180 people had been tested and 20 high-risk contacts were quarantined, with results returning negative so far. Authorities emphasised caution but urged the public not to panic as the investigation continues.

Containment measures and why Nipah is taken seriously

Nipah is a zoonotic infection and is associated with high mortality in severe cases. With no specific cure or vaccine widely available, outbreak response tends to focus on early detection, infection control in healthcare settings and rapid isolation of potential contacts.

Officials have also moved to identify possible animal reservoirs and transmission routes, including collecting samples from bats and conducting surveillance across parts of West Bengal. Public advisories have focused on basic precautions such as hygiene practices, avoiding exposure to bats, and safe handling of food products that could be contaminated in the environment.
