The Center for COVID-19 Situation Administration (CCSA), the country's COVID-19 task force, reported 209 new deaths, raising the cumulative fatalities to 7,552 since the pandemic began.

The Thai capital Bangkok continued to top the list of regions by new infections, with 4,215 new cases confirmed over the last 24 hours.

To contain the fast spread of the viral disease, Bangkok and 28 other provinces have been put under partial lockdown measures, including travel curbs, shopping mall closures and night-time curfews. The CCSA authorities are scheduled to meet on Monday to review the situation and the necessity to extend the measures until the end of August.

The Thai government has also been accelerating vaccine roll-out amid efforts to build herd immunity. As of Saturday, it had administered about 23.5 million doses of vaccines, with more than 7 percent of the country's nearly 70 million people having been fully vaccinated, according to the CCSA.
