South Korea shows what "world-beating" coronavirus tracing programme looks like

This story from South Korea shows just how far they have to go to get a system which is truly 'world-beating'. Having thought they had beaten coronavirus completely, officials detected a coronavirus outbreak centred on a nightclub in the Itaewon district in Seoul. Their contact tracing system kicked into gear and tracked down and tested a remarkable 65,000 people who had been to the clubs in the area or been in contact with those who had. Results came back the next day and 170 tested positive for Covid-19 and were put into quarantine. 89 of those had been to the clubs and bars in Itaewon, while the rest had caught the disease from these people.
