Tokyo reported 187 new COVID-19 cases on March 22, 12 more than a week ago, metropolitan health officials said, the first day after a state of emergency was lifted for the capital and three neighboring prefectures. 

The seven-day case average per day over the week through March 22 for Tokyo was 302.9, representing an increase of 5.3 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, stood at 47, the same as the day before.

Of the newly confirmed infections, 39 patients were in their 20s, followed by 35 in their 40s and 29 in their 30s. Thirty-eight patients were 65 or older.
