Tokyo registered 148 new COVID-19 cases on Aug. 30, the first time in five days the count has fallen below 200, according to metropolitan health officials.

However, the number of patients in serious condition in the capital rose by two to 34 from Aug. 29.

Serious cases refer to patients on a ventilator or extracorporeal membrane oxygenation, an ECMO lung bypass machine, according to the metropolitan government’s definition.

Of the new cases, patients in their 20s and 30s accounted for half the total, at 41 and 37, respectively.

They were followed by 23 people in their 40s, 16 in their 50s, eight in their 60s, six each in their teens and 80s, four each in their 70s and 90s and three under age 10.

The infection cases announced on Aug. 30 basically reflect the results of testing conducted about three days prior. Preliminary figures showed that 5,236 tests were performed on Aug. 27.
