Ten soldiers were found to have high fever by airport screening staff and were immediately rushed to Phramongkutklao Hospital in Bangkok to test for Covid-19, the source added.
Another soldier was sent to the hospital as well due to an injury on his finger that required a surgery.
The 140 other returnees were transported to state quarantine facilities in Chonburi province and will remain there for 14 days.
Maj-General Yutthachai Thianthong, commander of 14th Military Circle and coordinator of the training programme, said that the Army will employ strict measures to keep the returnees in quarantine facilities and make sure that no one can slip out. “We have added checkpoints and surveillance staff to monitor all entrances, exits and public areas within the facilities at all times,” he added.
