Speaking after a meeting on the matter with involved state agencies, he said the workers will be screened before departure and anyone showing fever will be barred from flights home.
Anyone showing fever in mid-flight will be moved to a separate seating area.
And all with fever will be put in quarantine on arrival to be tested for Covid-19 virus infection.
Prayut said the Thais who’ve been working in Daegu, epicentre of the virus outbreak in South Korea, and in North Gyeongsang province, will be kept in quarantine for 14 days at facilities run by the state, not in their homes.
The government is seeking more locations that can serve as quarantine facilities, since some 10,000 Thais – all of whom have been working in South Korea illegally – will gradually be coming home.
Thai authorities, loaned an AirAsia passenger jet for the purpose, last month evacuated 138 Thais from Wuhan, where the outbreak originated.
Whether ill or not, they were obliged to spend 14 days under observation at Sattahip Naval Base in Chonburi.
