Tokyo confirmed 555 new novel coronavirus infections on April 7, the first time the daily count topped 500 since Feb. 6.

The tally was 141 more than that of the previous Wednesday, when 414 new infections were confirmed in the capital.

The seven-day case average per day over the week through April 7 for Tokyo stood at 417, an increase of 15.6 percent over the previous week, records show.

Of the newly confirmed infections, 178 patients were in their 20s, followed by 97 in their 30s and 84 in their 40s. Sixty-three patients were aged 65 or older.

The number of serious COVID-19 cases requiring ventilators or an extracorporeal membrane oxygenation (ECMO) device, which circulates blood through an artificial lung, stood at 41, three fewer than the day before.
