Tokyo confirmed 475 novel coronavirus infections on April 1, continuing the steady uptick in new COVID-19 cases in recent weeks, metropolitan health officials said.

The last time the single-day count in the capital was above 470 was on Feb. 10, when 491 cases were reported.

The daily average for the week through April 1 was 372.3, an increase of 16.4 percent from the preceding week, officials said.

Of the newly confirmed infections, 114 patients were in their 20s, followed by 93 in their 30s, 64 in their 50s, and 55 in their 40s. Eighty-seven patients were 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 44, down one from the previous day.
