Health officials throughout Asia and the United States have intensified surveillance measures following India’s confirmation of two human Nipah virus cases in West Bengal. The patients, both nurses, have demonstrated signs of recovery and have since tested negative for the virus, authorities reported this week. The male nurse has been released from hospital treatment. The female nurse, though no longer positive for the virus, continues to receive medical care under observation. A government official informed news agency PTI that she has been taken off ventilator assistance and her health status has significantly improved, although medical professionals indicate she remains under careful supervision.
Close to 200 people who had contact with the infected patients are presently under medical monitoring. Following the confirmed cases, multiple Southeast Asian nations, including Pakistan, Singapore, Thailand, Malaysia, Hong Kong, Vietnam, Indonesia, Nepal, and the Philippines, have implemented preventive protocols. These measures encompass temperature checks at border crossings, evaluations of travel backgrounds, and required health disclosures for incoming travelers.
Though the Nipah virus has not been detected in the United States, infectious disease specialists emphasize the need for vigilant observation. Dr. Krutika Kuppalli, a Texas-based expert and former World Health Organization adviser, told the Daily Mail that even contained outbreaks merit serious consideration from international health organizations.
She emphasized that Nipah is classified as a high-risk pathogen and that rigorous surveillance, open information exchange, and readiness protocols are crucial. She further underscored the significance of global collaboration, pointing to the WHO’s central function in managing responses and providing current field data. A representative from the US Centers for Disease Control and Prevention stated that the organization maintains ongoing dialogue with Indian health officials and continues to track the situation, noting readiness to provide support if requested.
The World Health Organization reports that Nipah virus infections can present with vastly different degrees of severity. Certain individuals may remain asymptomatic, whereas others may experience respiratory complications or critical encephalitis, a dangerous swelling of the brain. Initial symptoms typically consist of fever, headache, muscle aches, vomiting, and sore throat.
