South Korea on Monday reported 473 new coronavirus patients.
The virus tally slightly simmered down to below 500 for the first time in 6 days, but this could be the result of slightly reduced testing over the weekend.

Seoul city saw 149 cases, Gyeonggi-do province.. 108 new cases, and Incheon reported 19 cases.

The second largest city in South Korea, Busan, saw 46 new cases, while the third-largest, Daegu, followed with 22 new cases.
Cluster infections stood out from workplaces, churches, and entertainment facilities.
A cluster that originated at a bar in Busan saw 33 more infection cases, with related cases now totaling up to 233.
And a traveling church group ended up causing a total of 71 linked infections in 8 different cities and provinces.
Concerns are growing over a fourth nationwide wave of infections. which health authorities say, might be looming right around the corner.
And when it comes, they say that it might result in more than 1000 infections a day.
