An outbreak of the deadly Nipah virus in India's West Bengal state has raised concerns across parts of Asia, leading to tightening airport screening measures.
Thailand has initiated screenings for passengers at three airports accommodating flights from West Bengal. Similarly, Nepal has begun screening at Kathmandu airport and other land border entry points from India.
As of early this month, five healthcare workers in West Bengal contracted the virus, with one reported in critical condition. Approximately 110 people who were in contact with the infected have been quarantined.
The Nipah virus, which can spread from animals to humans, is noted for its high mortality rate, ranging between 40% and 75%, with no approved vaccine or treatment available.
The Nipah virus can be transmitted from animals such as pigs and fruit bats to humans, as well as spread person-to-person through contaminated food. Classified by the World Health Organization among its top ten priority diseases, the Nipah virus is recognized for its potential to provoke severe outbreaks. Its incubation period ranges from four to 14 days, with symptoms ranging from fever and headaches to severe encephalitis in critical cases.
The Nipah virus first surfaced in 1998 among pig farmers in Malaysia, spreading to Singapore. Over 100 fatalities were recorded, necessitating the culling of a million pigs, which inflicted severe economic repercussions. Bangladesh has continued to witness Nipah virus fatalities with significant numbers since 2001, while multiple outbreaks have also occurred in India.
Last week confirmed five cases linked to a private hospital in Barasat, with specific attention paid to two nurses in an intensive care unit, one remaining in critical condition. Despite no cases being reported outside of India as of now, nearby nations are amplifying their preventive measures. In Thailand, health declarations for passengers from the affected flights have become mandatory, and stricter screenings are being enforced in areas frequented by tourists. Furthermore, Taiwan's health authorities propose to categorize the Nipah virus as a 'Category 5 disease', indicating the need for immediate reporting and strict control measures.
