Tokyo posted 24 new deaths from COVID-19 on Feb. 17, setting another single-day record in the current sixth wave of infections that started in January.

The same day, the capital reported 17,864 new COVID-19 cases, the ninth consecutive day of decline from the same day the previous week, metropolitan health officials said.

Of the 17,864 cases, 742 patients were diagnosed with COVID-19 by doctors without testing.

The seven-day average of new cases over the week through Feb. 17 was 14,936.1, which is 83.7 percent of the figure for the preceding week.

The 24 patients who died ranged in age from their 40s to 100s. The death toll rose by three from the previous record of 21, set on Feb. 16.

The number of patients in serious condition remained unchanged from the previous day at 81 in the capital. The metropolitan government defines patients on ventilators or ECMO heart-lung bypass machines as serious cases.

The same day, Osaka Prefecture reported 13,912 new cases, up 1,084 from a week ago, and 54 new deaths.
