Tokyo confirmed 279 new COVID-19 cases on March 4, down from 340 cases reported on Thursday a week ago, according to metropolitan government officials.

The latest tally brought the daily average for the week in the capital through March 4 to 269.1, or 96.2 percent of the figure for the preceding week.

The metropolitan government has set a weekly goal of reducing the average to 70 percent of the previous week.

The number of serious cases in Tokyo requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, dropped by one from the previous day to 51 on March 4, the officials said.

Of the 279 cases, 71 patients were in their 20s, followed by 40 in their 30s and 36 in their 40s. There were 62 patients aged 65 or older.
