Tokyo logged 256 new cases of COVID-19 on Aug. 22, the third straight day of reporting more than 200 fresh infections.

Of that figure, patients in their 20s and 30s together represented 64 percent of the total, at 100 and 64, respectively, officials of the Tokyo metropolitan government said.

Thirty patients were in their 40s and 25 in their 50s. Twelve cases involved patients in their 60s, 10 in their 80s and six in their 70s.

Of the remainder, five were teenagers and four were under the age of 10.

The latest figures mostly reflect people whose infections were confirmed on Aug. 19, when 4,187 tests were conducted, according to preliminary statistics released by Tokyo metropolitan authorities.

The number of tests was nearly 2,000 fewer than the peak testing period on Aug. 11.

The number of patients in Tokyo deemed to be in a serious condition rose to 37, up four from the previous day. Such cases more than doubled, compared with the 15 on Aug. 1.

The metropolitan government defines seriously ill patients as those either on a ventilator or an extracorporeal membrane oxygenation (ECMO) lung bypass machine.
