The cumulative caseload came to 24 million-831-thousand-761.

The latest tally was down over two-thousand from a week ago and some seven thousand than two weeks ago.

This is the lowest Monday figure in about 13 weeks since July 4, when the country's latest wave saw an upsurge in infections.

The number of seriously or critically ill patients in the hospital came to 361, up eight from a day earlier. The figure has been remaining in the 300 range for six days.
