Tokyo reported 4,392 fresh cases of COVID-19 on Aug. 22, the most for a Sunday, and eight deaths.

Osaka Prefecture, meanwhile, reported more than 2,000 new cases, the fifth day in a row for the figure to top 2,000, and Mie Prefecture logged a record 432 new cases, setting a record for the sixth consecutive day.

The seven-day average of newly confirmed infections in the capital over the week through Aug. 22 came to 4,732.9, up 11 percent from the figure for the preceding week, metropolitan officials said.

Serious cases, which Tokyo defines as those where patients require a ventilator to breathe or an ECMO lung bypass machine, rose by one to 271. Other prefectures include patients in ICU units in their figures.

Patients in their 20s accounted for 1,341 of the 4,392 newly confirmed cases, followed by 845 in their 30s, 711 in their 40s and 484 in the 10 to 19 age bracket.

The number of patients in their 50s stood at 444, while those aged 65 or older accounted for 208 cases.
