Suvarnabhumi airport director Raweewan Netarakavesana said on Friday that passengers and airplanes from disease risk countries, especially those from Africa, were already being thoroughly checked.
People from those countries must present documents showing their yellow fever vaccination and they would be under close watch during their stay, she said.
Mrs Raweewan said Suvarnabhumi airport did not receive direct flights from the Ebola-infected countries -Guinea, Liberia and Sierra Leone - but there were direct flights from other African nations.
Airlines that operated direct flights from Africa were Ethiopian Airlines, South African Airways and Thai Airways International, she said.

Thermal scanners have not yet been used at the airport.
The Ministry of Foreign Affairs advised Thais not to travel to the countries where Ebola was spreading. It asked those who must visit there to inform the Thai embassy in Dakar, Senegal, of their flight, accommodation and phone number for contact in case of emergency.
