Personnel at Suvarnabhumi and Don Mueang airports in Bangkok, along with Phuket airport, have initiated heightened screenings of incoming travelers, particularly those from West Bengal starting Sunday, according to the Bangkok Post.

Procedures include temperature screenings and on-the-spot evaluations of passengers exhibiting signs of illness.

Individuals identified with a high temperature or symptoms indicative of Nipah will be moved to quarantine facilities. Those who exhibit symptoms within 21 days post-arrival are urged to seek immediate medical assistance and inform healthcare providers about their travel history and the onset date of symptoms.

Almost 700 individuals from the affected region enter Thailand daily through the three primary airports.

Thailand has yet to identify any Nipah cases and has never documented a case in the past.

Indian authorities are hurrying to control a Nipah virus outbreak in West Bengal, where five cases have been verified in regions near Kolkata, including instances among healthcare personnel, according to China's Global Times.

Approximately 100 individuals have been placed in quarantine after the virus was discovered at a medical facility.

A doctor, a nurse, and a staff member tested positive following the initial two confirmed cases, a male patient and a female nurse, as reported by the U.K.'s The Independent.

Nipah is a zoonotic virus that transmits from animals to humans and, in some instances, from human to human, as stated by the World Health Organization (WHO).

According to WHO, Nipah can vary from mild illness to severe respiratory infection and deadly encephalitis, with a fatality rate ranging from 40-75% based on the outbreak and the capacity of the healthcare system.
