The government reported zero new coronavirus cases and no new deaths on Monday, leaving the total number of infections in Thailand at 3,135 with 58 deaths since January.
Dr Taweesilp Visanuyothin said no locally-transmitted infections have now been recorded for exactly three weeks.
"I must thank everyone for their efforts during this exhausting period of time. Lockdown relaxation has been applied in stages. Today is the first day when businesses and activities in the highest risk category can resume. We don’t know if we will be able to maintain this disease-free status," he said.
The death toll remained at 58 and the number of recovered patients was unchanged at 2,987. Ninety patients were receiving treatment at hospitals.
