As of Sunday, 1,707 Americans had been tested for the novel coronavirus, according to the Centers for Disease Control and Prevention. South Korea, by contrast, has tested more than 189,000 people. The two countries announced their first coronavirus cases on the same day.
In the US, test-kit shortages have hampered health authorities' ability to get a clear sense of how many Americans are infected. Compared with many other countries affected by the coronavirus, in fact, the US has done the fewest COVID-19 tests per capita.
