The number of new cases was lower than the 15 recorded yesterday and the 53 on Saturday.
It was the first single-digit rise since March 14. Since testing has been limited, the actual number of infections may be much higher.
It is the first time since the outbreak started in January that there have been no new local transmissions reported in Bangkok, said Taweesilp Visanuyothin, a spokesman for the government’s Centre for COVID-19 Situation Administration.
Of the new cases, three were linked to previous cases, two are arrivals from overseas that have been under state quarantined, and four others were reported from the southern province of Yala, where the authorities are aggressively testing the population due to high infection rates.
Since the outbreak escalated on January 2, a total of 609 patients have recovered and gone home.
