검사 횟수와 신속성의 중요성이 좀 더 언급되는 것 같네요.

As the global death toll passed 3,000, South Korea on Monday confirmed 599 new cases, far higher than the daily tally reported in China. With 4,335 confirmed infections and at least 22 deaths, South Korea has the second-largest national caseload. However, it has tested more than 100,000 people, far more than most nations.

In the United States, tests have taken place at a far slower pace. A genetic analysis suggested that the coronavirus, which causes a highly infectious respiratory disease called covid-19, has been spreading undetected for about six weeks in Washington state. The U.S. Food and Drug Administration on Saturday took steps to sharply expand testing.
