Of the 191 new cases, 43 patients, the highest number, were in their 20s, followed by 38 in their 30s, 33 in their 40s and 30 in their 50s. Twelve patients each were in their teens and 60s. Eight patients each were in their 70s and 80s. Five patients were under 10 and two were in their 90s.

The number of patients with severe symptoms, who were on a ventilator or on an extracorporeal membrane oxygenation, an ECMO lung bypass machine, decreased by one from the previous day to 21.
