Asian Airports Reinstate Health Screening After Nipah Virus Cases Emerge In India

Health authorities across Asia have reactivated strict health screening measures at major international airports after a cluster of Nipah virus infections in India’s West Bengal state triggered regional concern. The virus, known for its high fatality rate and lack of specific treatment, has prompted some governments to revive protocols reminiscent of the COVID-19 pandemic to curb potential cross-border spread. 

In West Bengal, five confirmed cases of Nipah virus have been reported, and around 100 individuals identified as contacts are under quarantine as containment efforts continue. The affected cluster includes healthcare workers who contracted the virus while treating patients, prompting intensified local public health measures. 

In response, Thailand, Nepal and Taiwan have introduced enhanced health checks for passengers arriving from the affected region. Temperature screening, symptom assessments and health questionnaires are being used to identify individuals who may be infected. Special health advisory cards outlining warning signs and required actions have also been distributed at some airports as part of the heightened surveillance. 

Thailand’s Ministry of Public Health has specifically screened more than 1,700 travelers arriving from Kolkata, with no Nipah infections detected so far. Three major hospitals in Bangkok have been placed on alert and prepared to manage suspected cases if they arise. Authorities emphasize that while Nipah does not spread before symptoms appear, the virus can cause severe illness, so early detection remains critical. 

Officials in Nepal have strengthened checks at Tribhuvan International Airport and land border crossings with India, and Taiwan plans to classify Nipah infection as a top-tier notifiable disease to enable rapid reporting and response. 

Public health experts stress that Nipah is a zoonotic virus — typically carried by fruit bats and occasionally transmitted to humans through direct contact or contaminated food — and can lead to symptoms ranging from fever and headache to fatal encephalitis. It has a high death range – ranging from 40% to 75%.

Given its high case-fatality rate and lack of cure, authorities are focused on surveillance, isolation of suspected cases, and cooperation between neighboring countries to prevent wider spread.
