Tokyo, under the embrace of a state of emergency, has now gone three weeks in a row with daily COVID-19 cases staying under 500.

Metropolitan government officials said Feb. 27 the capital had confirmed 337 fresh cases. While that marked 21 straight days of less than 500 new cases, the figure was 10 more than the previous Saturday.

Of the latest cases, 77 patients were in their 20s, 63 in their 30s, 54 in their 40s and 44 in their 50s. Officials said 56 patients were aged 65 or older.

Sixty-eight patients displayed serious symptoms that require ventilators or an extracorporeal membrane oxygenation (ECMO) device, which circulates blood through an artificial lung. The figure represents a decrease of two from the previous day.
