The 12 boys and their coach lost an average of 2 kg (4.4 lb) during their 17-day ordeal but were generally in good condition and showed no signs of stress, a senior health official said on Wednesday.
They were taken by helicopter to a hospital about 70 km (45 miles) away to join their team mates in quarantine for the time being.
“From our assessment, they are in good condition and not stressed. The children were well taken care of in the cave. Most of the boys lost an average of 2 kg,” Thongchai Lertwilairattanapong, an inspector for Thailand’s health department, told reporters.
