Tokyo reported 2,612 new cases of COVID-19 and a record 176 serious cases requiring a special breathing apparatus on Aug. 10, metropolitan heath officials said.

The capital logged nine more serious cases than the day before, topping its previous record of 160 set on Jan. 20 during the third wave of infections.

Tokyo's latest daily count of new cases fell by 1,097 from a week ago.

The seven-day average of newly confirmed infections in the capital over the week through Aug. 10 was 3,978.7, up 19.2 percent from the figure a week ago.

But only 5,928.3 tests were performed a day on average from Aug. 7 to Aug. 9, which were three consecutive holidays.

Tokyo uses its own standards of categorizing cases, which differs from other prefectures, classifying only patients on a ventilator or an ECMO heart-lung bypass machine as serious cases.

Officials said there were three new deaths from COVID-19.

Of the 2,612 new cases, patients in their 20s totaled 844. They were followed by 560 in their 30s, 420 in their 40s, 296 in their 50s and 225 teenagers. Patients 65 or older accounted for 103 new cases.
