An asymptomatic male, 56, who returned from Singapore and entered state quarantine on August 7 tested positive on his 11th day, CCSA spokesman Dr Taweesin Visanuyothin said.
Meanwhile, one patient was discharged and returned home.
As of August 21, the total number of confirmed cases in the country stood at 3,390 (453 in state quarantine) -- 113 are under treatment, 3,219 have recovered and been discharged, and there have been 58 deaths.
Globally, the total number of confirmed cases increased to 22.8 million, up by 276,000 on Friday, of whom 15.5 million have recovered while deaths stood at 791,000. Thailand ranks 115th for most cases in the world. The US has the highest number (5.74 million), followed by Brazil (3.5 million) and India ( 2.9 million).
Explaining the case of a 35-year-old woman who tested positive outside state quarantine on Wednesday, the CCSA spokesman said she tested positive for antibodies in the blood, which was almost impossible to spread to others, according to the Department of Disease Control. However, 24 people who had close contact with her had agreed to undergo tests.
Dr Taweesin urged Thai people to continue wearing a mask and follow good health practices, as there is a risk of infection because of the increasing number of cases globally.
He said 799,936 samples have been tested nationwide (0.43 per cent positive rate) and 71 out of 77 provinces of Thailand have got their own virus lab testing facility. The aim is for every province to have such a facility, he said.
