Tokyo health officials confirmed 405 new COVID-19 cases on April 19, up 99 from the 306 reported a week earlier.

The daily count exceeded 400 on a Monday for the first time since the 619 logged on Jan. 25.

Monday tallies tend to be lower than other days of the week as they reflect infections confirmed about three days earlier, close to the weekend, when fewer tests are typically conducted for the virus.

Metropolitan government officials said the daily average of new cases for the week ending April 19 was 600.6, or 126.1 percent of the figure of the previous week.

Of the latest cases, 86 patients were in their 20s, 85 in their 30s and 58 in their 40s and 50s each. Fifty-two people aged 65 or older tested positive for the novel coronavirus.

The number of serious cases in Tokyo requiring ventilators or extracorporeal membrane oxygenation, also known as an ECMO lung bypass machine, rose by two from the previous day to 47 on April 19, the officials said.
