Tokyo confirmed 258 new COVID-19 cases on Aug. 21, the second consecutive day the count exceeded 200 after 339 infections were reported the day before.

Of the 258 cases, 83 are people in their 20s and 54 are in their 30s. Patients in those age brackets accounted for 53 percent of the total.

As for other age groups, 40 cases involve people in their 40s, 33 are those in their 50s, 12 in their 60s, nine in their 70s and eight in their 80s.

Ten teenagers and nine children under the age of 10 also tested positive.

The capital’s daily tally announced by the Tokyo metropolitan government reflects the results of tests conducted to check for infections about three days earlier, according to officials.

A total of 5,407 tests were carried out on Aug. 18 on a preliminary basis, more than 1,000 fewer than the highest figure to date recorded on Aug. 11.

The metropolitan government uses its own standard in reporting the number of seriously ill COVID-19 patients in the capital by counting the number of patients on a ventilator or an extracorporeal membrane oxygenation, which is a lung bypass machine.

By that standard, Tokyo had 33 patients with serious symptoms on Aug. 21, down three from the previous day. But the figure is still more than double the 15 reported on Aug. 1.
