An outbreak of the deadly Nipah virus in India's West Bengal state has sparked concern in parts of Asia, leading to tightened screening measures at airports.
Thailand has begun screening passengers at three airports receiving flights from West Bengal, and Nepal is screening arrivals at Kathmandu airport and other land border points with India. So far, five healthcare workers in West Bengal have been infected, with one critically ill and around 110 quarantined.
The Nipah virus, which spreads from animals to humans, has a death rate ranging from 40% to 75% with no current vaccine or effective treatment. Initial symptoms can include fever, headaches, and respiratory problems, but it may escalate to severe conditions like encephalitis.
Historically, the Nipah virus was first recognized in 1998 in Malaysia. Recent outbreaks in India have also occurred, particularly in Kerala. As of now, there are no cases reported outside India, but several countries are increasing their health checks.
Health authorities in Thailand and Nepal are taking precautions to minimize the risk of an outbreak, while Taiwan is considering classifying the Nipah virus as a significant public health threat.
