West Bengal has recently been placed on high alert following the confirmation of two Nipah virus cases. This zoonotic infection is notorious for its high fatality rate, making it a public health concern. The confirmation was provided by the National Institute of Virology in Pune after re-testing samples from two nurses admitted to a hospital in Barasat.
The initial tests were conducted at AIIMS Kalyani, and the samples were subsequently sent to the National Institute of Virology for further confirmation. Unfortunately, both nurses diagnosed with the virus are in critical condition and require ventilator support. One of the patients is reported to be in a coma, raising alarm among health officials.
A house staff doctor at a Burdwan hospital, who had close contact with one of the infected nurses, has developed mild fever and is currently under observation.
The West Bengal health department has taken swift action by identifying over 120 close contacts of the two nurses. This group includes family members, healthcare workers, ambulance drivers, and other medical staff. All identified contacts have been placed under home isolation to prevent further transmission.
Contact tracing efforts are ongoing, and samples from several contacts have been sent for testing at AIIMS Kalyani. In Katwa and Burdwan districts, dozens of medical professionals are under observation as a precautionary measure.
Health officials are currently probing the source of the infection. Preliminary investigations suggest that the nurses might have contracted the virus through human-to-human transmission at the Barasat hospital, where a healthcare worker had previously died from Nipah-like symptoms.
Other potential sources of infection include exposure to contaminated fruits or raw date palm sap, as these are known transmission routes through fruit bats. Notably, both nurses had traveled within West Bengal to East Midnapore and Katwa but did not have significant travel history outside the state.
The Nipah virus is a zoonotic disease transmitted from animals to humans. The natural reservoir for the Nipah virus is fruit bats of the Pteropus genus. Human-to-human transmission has been documented, especially in healthcare settings, emphasizing the need for strict infection control protocols.
The National Institute of Virology in Pune serves as India’s apex laboratory for managing viral outbreaks, playing a crucial role in the current situation.
A dedicated panel is coordinating closely with a National Joint Outbreak Response Team dispatched by the Union health ministry. Health authorities are implementing strict infection control measures in all affected hospitals, while surveillance efforts are heightened to prevent further spread of the virus.
