Tokyo confirmed 460 new COVID-19 cases on Dec. 15, the most for a Tuesday, and reported 78 patients in serious condition, the highest figure since the state of emergency was lifted in late May.

The daily infection tally topped the previous Tuesday record of 372 set on Dec. 1, according to metropolitan government officials.

The officials said the number of serious cases requiring ventilators or lung bypass machines rose by five from the previous day.

The Tokyo metropolitan government on Dec. 10 said it has increased the number of beds for patients with severe COVID-19 symptoms from 150 to 200. Those beds are filling up as the number of serious cases continues to rise.

As of Dec. 14, 2,049 patients were hospitalized with COVID-19 in the capital, topping 2,000 for the first time since comparable data became available on May 12.
