The daily number of new COVID-19 cases nationwide exceeded 80,000 for the first time on Jan. 28 with a record 17,631 cases reported in Tokyo.

It marked the fourth consecutive day that figures for the entire nation and the capital each set new records.

Hyogo Prefecture confirmed a record 4,342 new infections the same day, while the figure for Osaka Prefecture topped 10,000 for the first time with 10,013.

Tokyo’s latest tally was up roughly 1.8-fold from the 9,699 cases reported a week ago and brought the daily average of new infections in the capital over the week through Jan. 28 to 12,895.1, or about twice the figure for the preceding week, when it was 6,193.

The average number of diagnostic tests conducted in the capital over the three days through Jan. 28 stood at 28,351.

Three new deaths among patients in their 80s to 90s were also reported in Tokyo.

The number of serious cases in the capital requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, rose by two from the previous day to 20.

Of the 17,631 cases, 3,946 patients were in their 20s, followed by 3,407 in their 30s, 2,886 in their 40s and 1,654 in their 50s. There were also 2,165 patients under 10, 1,925 between the ages of 10 and 19 and 1,201 aged 65 or older.

As of Jan. 27, 46.1 percent of hospital beds were occupied in Tokyo, which said it will consider asking the central government to declare a state of emergency if the rate hits 50 percent.
