An outbreak of the deadly Nipah virus in India's West Bengal has led to increased screening measures at airports across Asia, including Thailand, Nepal, and Taiwan. The virus, which has a high fatality rate of 40% to 75% and no available vaccine or treatment, has infected five healthcare workers in West Bengal, with some in critical condition. The virus transmits from animals such as bats and pigs to humans and can spread person-to-person through contaminated food or bodily fluids, with symptoms ranging from mild fever to severe encephalitis. Past outbreaks have occurred in Malaysia, Singapore, Bangladesh, and India, notably in Kerala, with recent cases in 2023. The current Indian cases are linked to a hospital in Barasat, with no reports of spread beyond India so far. Countries like Thailand and Nepal have begun screening travelers from West Bengal, and Taiwan is proposing to classify Nipah as a Category 5 disease, indicating a major public health risk requiring immediate reporting and control measures. Taiwan's CDC has also announced plans to list Nipah as a Category 5 notifiable disease following the recent Indian outbreak, which would impose strict reporting and control protocols. Despite this, Taiwan maintains a Level 2 travel advisory for Kerala, urging caution but not restricting travel. Authorities warn that fruit bats are the natural reservoir of the virus, and contaminated raw foods, especially coconut juice, pose risks. Overall, health officials worldwide are taking precautionary measures amid fears of potential epidemic spread, emphasizing the importance of surveillance, early detection, and public awareness.
