Andrew Noymer, UCI associate of professor, public health [said] “When you have a case, you contact 10 people. You ask them ‘who did you meet within the last 5 days?’ If you get a list of, say, 10 people, then you contact those 10 people. It’s very labor-intensive when done thoroughly, but South Koreans are set up for this.”
