Tokyo confirmed 1,600 new COVID-19 cases on June 10, down 511 from a week ago, marking the 28th straight day of a week-on-week decline.

The deaths of three patients in their 70s to 90s were also reported in the capital.

The daily average of new cases over the week through June 10 in Tokyo was 1,697, or 77.6 percent of the average for the preceding week.

People in their 20s represented the largest age group of the new patients at 346, followed by 309 in their 30s, 251 in their 40s, 209 aged between 10 and 19, 208 under 10, and 137 in their 50s.

Additionally, 107 people aged 65 or older tested positive.

The occupancy rate of hospital beds for COVID-19 patients in Tokyo was 14.7 percent, while 3.8 percent of hospital beds for severely ill patients were filled, officials said.

The Tokyo metropolitan government said it would consider asking the central government to issue a state of emergency for the capital if the occupancy rate of beds for seriously ill patients reached between 30 and 40 percent.

The metropolitan government defines seriously ill patients as those requiring ventilators or ECMO lung bypass machines.

Their number increased by two from the previous day to four on June 10.
