Two Nipah virus cases reported near Kolkata: health teams step up surveillance, testing and quarantine
Authorities in India have confirmed two Nipah virus infections involving nurses at a private hospital near Kolkata, triggering quarantine and surveillance measures. Officials have tested hundreds of contacts and expanded monitoring as investigations look at a suspected index patient, while public health teams emphasise containment, infection-control protocols and community awareness due to Nipah’s high fatality risk.
What’s been confirmed
Indian health authorities have confirmed two Nipah virus cases in West Bengal, involving two nurses at a private hospital near Kolkata. Reports said one of the nurses is in critical condition, prompting a rapid public health response given Nipah’s potential severity and the need to quickly identify and isolate contacts.

Suspected source and hospital link
Officials indicated that initial assessments pointed to exposure after treating a patient with severe respiratory symptoms who later died before being tested, and that the patient is being treated as a suspected index case. This has led to scrutiny of infection-control practices, contact tracing inside the facility and a tighter surveillance net for those who interacted with the patient and the two infected nurses.
Testing, quarantine and surveillance
Authorities have expanded testing and placed high-risk contacts under quarantine, while monitoring continues for symptoms among those exposed. Public health agencies—including national-level teams—have been mobilised to support containment efforts, and officials have also looked at potential animal reservoirs as part of the investigation.
Public guidance and risk communication
Health officials have urged adherence to preventive measures, including avoiding exposure to bats and practising hygiene and protective protocols in healthcare settings. While emphasising vigilance, authorities have also signalled that surveillance and testing are intended to prevent wider spread and that containment actions will be adjusted as results come in.
- Immediate focus: isolate cases, trace contacts, test and quarantine high-risk exposures
- Investigation: determine exact transmission chain and source
- Prevention: infection-control reinforcement and community awareness
