Here's some actual information detailing the South Korean deployment of WHO kits, something your ass pretended didn't matter before misrepresenting.

How South Korea Scaled Coronavirus Testing While the U.S. Fell Dangerously Behind
“With our past experience with MERS,” he wrote in an email, “we found it very important to diagnose people quickly and to prevent spread to the community through isolation of infected people.”
The quick fielding of a widely available test gave South Korea a key advantage in fighting the spread of the disease, said Dr. William Schaffner, a professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center.
“They used the WHO test, so they had a test that was validated early on. Then, they made a simple decision: Test as many people as possible. They organized themselves to get specimens and then made sure they had a very high throughput in the labs.”
“This was crucial to figuring out where the infection was and where it was not, and then they used this knowledge to direct their public health efforts.”
In America, the CDC initially set the parameters of who could be tested narrowly, reflecting the scarcity of the test kits. The rules limited testing to people who had been to countries with known hot spots, even while epidemiologists warned that such restrictive criteria would mean missing early detection of cases in which the virus was spread among people with no links to travelers. This limitation appears to have given the disease a head start in some communities, notably Seattle. Then, even when criteria were loosened, the ongoing lack of testing capacity meant that the disease continued to spread, untracked.
You willful idiot.
