BANGKOK, Jan. 26 (Xinhua) -- Thailand's Civil Aviation Authority announced that it will implement comprehensive screening for all flights arriving from India's West Bengal, a high-risk region for Nipah virus, starting from 00:00 local time on Monday to prevent the virus from entering the country.

In a statement released on Sunday, the authority said the screening measures will be adjusted dynamically based on the evolving situation.

Key protocols currently in place involve airlines conducting preliminary health checks at the point of departure. Passengers who exhibit symptoms that call for further testing are required to present relevant medical certificates before boarding and must adhere to public health guidelines throughout the flight.

Upon arrival in Thailand, all travelers will undergo temperature checks and be required to fill out a health declaration form. Dedicated screening stations have been set up in the jet bridge areas of designated airports.

According to Thai media reports, direct flights operate between Kolkata in West Bengal and three major Thai airports -- Suvarnabhumi, Don Mueang, and Phuket, where the screening measures have already been rolled out.

No Nipah virus cases have been reported in Thailand so far, authorities said on Sunday.

According to the World Health Organization and other health bodies, the Nipah virus primarily targets the lungs and brain. Symptoms include fever, headache, drowsiness, confusion, and coma, with a mortality rate exceeding 40 percent among infected patients.
