Tokyo confirmed 290 COVID-19 cases on March 9, up 58 from the 232 new infections reported a week ago, according to metropolitan government officials.

The tally brought the daily average for latest week in the capital to 261.7, or 99.5 percent of the figure for the preceding week.

The number of serious cases in Tokyo requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, dropped by seven from the previous day to 39 on March 9, the officials said.

Of the 290 cases, 48 patients were in their 40s, followed by 45 in their 50s and 44 in their 20s. There were 73 patients aged 65 or older.

Tokyo has set a goal of 70 percent or less for the week-to-week differences in the daily averages. It has recently fallen short of this goal, and the COVID-19 state of emergency was extended for the capital and three surrounding prefectures until March 21.
