Tokyo logged 337 new COVID-19 cases on March 23, 37 more than a week ago, metropolitan health officials said.

New cases in the capital have topped the number recorded the same day in the previous week for four consecutive days.

The seven-day case average per day over the week through March 23 for Tokyo was 308.1, representing an increase of 6.6 percent from the preceding week, officials said.

The number of serious novel coronavirus cases requiring ventilators or an extracorporeal membrane oxygenation (ECMO) device, which circulates blood through an artificial lung, was 42, down five from the day before.

Of the newly confirmed infections, 86 patients were in their 20s, followed by 46 in their 30s and 43 in their 50s. Seventy-two patients were 65 or older.
