West bengal, India is battling a newly emergent outbreak of Nipah virus, a rare but deadly zoonotic disease, prompting swift public health measures [[1]]. As of January 25, 2026, five cases have been confirmed, including infections among healthcare workers, raising concerns about potential spread within medical facilities [[3]]. With a mortality rate ranging from 40% to 75% and no available vaccine, authorities are prioritizing contact tracing and quarantine efforts to contain the virus, which is typically transmitted from fruit bats and pigs to humans [[2]].
India’s West Bengal state is on high alert following a suspected outbreak of a deadly disease, prompting officials to implement emergency measures to prevent its spread. The situation is particularly concerning given the proximity of affected areas to densely populated regions.
SPREADS FROM BATS AND PIGS, CAN TRANSMIT BETWEEN PEOPLE
Health authorities have identified cases of Nipah virus in settlements near the state capital of Kolkata. An urgent contact tracing effort has been launched to control the outbreak, and individuals considered at risk are now under observation, according to health officials. This outbreak highlights the importance of swift public health responses to emerging infectious diseases.
As of January 25, 2026, testing has been conducted on 180 individuals, with 20 placed in quarantine as a precautionary measure. Experts emphasize that Nipah virus can be transmitted from animals to humans, particularly through contact with bats and pigs, and also carries the risk of human-to-human transmission. Fruit bats, commonly found throughout India, are known to be natural carriers of the virus.
HEALTHCARE WORKERS AMONG THOSE INFECTED
According to reports from Press Trust of India, three new infections were confirmed this week. These cases include a doctor, a nurse, and another healthcare worker. Earlier, two nurses – one male and one female – working at a private hospital in Barasat also tested positive for the virus.
Officials report that one of the nurses is in critical condition, exhibiting high fever and severe respiratory distress. The nurse reportedly fell into a coma after rapidly deteriorating following care for a patient experiencing severe respiratory failure who died before testing could be completed.
Authorities note that individuals infected with Nipah virus may initially show no symptoms, but can quickly develop acute respiratory issues. Common symptoms during the illness include high fever, headache, muscle pain, vomiting, and sore throat.
CAN LEAD TO COMA WITHIN 24 HOURS
In severe cases, the virus can cause inflammation of the brain, leading to coma within 24 to 48 hours. The mortality rate associated with Nipah virus infection ranges from 40% to 75%. Experts stress that there is currently no approved vaccine or effective treatment available for Nipah virus. The lack of readily available treatments underscores the need for continued research and preparedness for emerging viral threats.
