The government on Sunday reported 15 new coronavirus cases and no new deaths, bringing the total number of cases in Thailand since its outbreak in January to 2,922 cases and 51 deaths.
The number of new cases was a sharp drop from the 53 recorded on Saturday.
Of the new cases, four were linked to previous cases, another four had no known links, while five new patients are arrivals from overseas who have been under state quarantine.
Two other new cases were reported from the southern province of Yala, where the authorities are aggressively testing the population because of high infection rates there, said Taweesilp Visanuyothin, a spokesman for the government's Centre for Covid-19 Situation Administration.
Since the outbreak in Thailand, 2,594 patients have recovered and gone home.
Dr Taweesilp said measures to fight the virus, including social distancing practices and mask-wearing requirements, will be in place until at least early next year -- the earliest possible timeframe when a vaccine could be deployed to end the pandemic.
People cannot go back to the way they used to live before the outbreak, he said, because there could be an explosion of new cases if the country lowers its guard.
"Our two-digit numbers of new cases does not mean the situation is under control," Dr Taweesilp cautioned.
He stressed the need to stay at home and work from home to limit new contractions, because the fight against Covid-19 will go on for a long time.
"Our months of work will be a wasted effort" if we return to the lifestyle we practised before the virus broke out, he warned.
