A virus cluster connected to a call center in one of the busiest areas of Seoul has raised alarms that South Korea's outbreak -- thought to have been waning -- has gained a foothold in the more populated capital region.
More than half of South Korea's 51 million people live in the Seoul metropolitan area.
So far, 93 people have tested positive among the call center's employees and their families, Seoul Mayor Park Won-soon said Wednesday in a briefing broadcast over YouTube. The number could grow as tests are being done on more than 550 co-workers who worked on other floors of the Korea Building in Seoul's Guro district.
