Tokyo confirmed 2,001 new cases of novel coronavirus infections on Jan. 15, the first time the figure exceeded the 2,000 mark in a week.

The daily number of COVID-19 patients remained below 2,000 since the capital recorded 2,392 cases on Jan. 8. The count started climbing after dropping to 970 on Jan. 12, with 1,433 reported the next day and 1,502 on Jan. 14.

In Tokyo, 133 patients were listed in serious condition, down two from the previous day, metropolitan government officials said.

Tokyo defines serious cases as those requiring a ventilator or a machine called extracorporeal membrane oxygenation (ECMO), which circulates blood through an artificial lung.
