West Bengal reports Nipah virus cases among nurses; quarantine and surveillance stepped up
Indian health authorities have confirmed Nipah virus infections among two nurses at a private hospital near Kolkata, prompting quarantine, testing and surveillance measures. Officials are tracing contacts linked to a suspected index patient and conducting wider checks as Nipah—known for high fatality—has no specific cure or vaccine.
What officials have confirmed
Health authorities in India have confirmed Nipah virus infections involving two nurses at a private hospital near Kolkata, West Bengal. One of the nurses is reported to be in critical condition, and the development has triggered a rapid public health response due to Nipah’s potential severity and history of high case fatality in past outbreaks.

Officials have indicated that early assessment points to a patient previously admitted with severe respiratory symptoms as the likely source, with the patient treated as a suspected index case. The patient reportedly died before definitive testing could be completed, increasing the focus on retrospective tracing and hospital infection-control audits.
Testing, quarantine and surveillance
Authorities have initiated quarantine and surveillance measures, including identification of close contacts and testing in the local area. As per the report, a large number of people had been tested as of 20 January, and high-risk contacts were placed under quarantine with follow-up testing planned after the isolation period.
Given Nipah’s zoonotic nature, the response has also expanded to environmental surveillance. Testing of bats has been reported as part of efforts to understand possible reservoirs and reduce the risk of further spillover, since fruit bats are a suspected natural host in multiple documented outbreaks.
Public guidance and risk context
Nipah can spread from animals to humans and also through human-to-human transmission, with symptoms that may begin as fever and respiratory illness and can progress to neurological complications. There is no specific cure or widely available vaccine, so care is largely supportive and focused on preventing transmission.
Officials have advised precautionary steps such as avoiding exposure to bats, washing fruit before consumption, and using protective measures when handling animals or cleaning sheds, while also emphasising monitoring and controlled containment rather than panic.
