South Korea just flexed its contact-tracing power: After partiers with coronavirus went to nightclubs, it found and tested 46,000 exposed people
South Koreasuccessfully controlled its original coronavirus outbreak in just three weeks.
- After some infected partygoers spread the virus in several Seoul nightclubs in early May, South Korea saw another flare-up.
- The country was able to quickly control that second outbreak by finding more than 45,000 people connected to those nightclubs and testing and quarantining them.
- South Korea's guide to flattening the curve describes how it uses text alerts and smartphone apps to perform contact tracing and share information with the public.
South Korea's exemplary coronavirus control measures were put to the test this month.
After the country relaxed its social distancing as the number of new daily cases dropped into the single digits, several people who visited nightclubs in Seoul tested positive for the virus.The partiers had been out in the city's Itaewon entertainment district during the first weekend of May, after which dozens of new
More than 160 people tested positive, and were isolated and treated accordingly. By May 18, the country's new daily domestic cases had dropped back to nine.
South Korea's contact tracing is next-levelSouth Korea attributes its
To wrangle the nightclub-linked outbreak, officials tried to get in touch with every single person who'd visited any of the clubs where infected people went. That was possible because bars and nightclubs in Seoul required partygoers leave their names and contact information before entering, TIME reported. But not all of them left accurate or complete information, so police worked with telecommunications companies to use cell-phone data to confirm who was in Itaewon that weekend.
According to Seoul's mayor, officials were able to get in touch with about half of nightclub visitors by May 10.
South Korean contact tracers also use interviews, GPS tracking, credit-card records, and video surveillance to trace people's travel histories, The Washington Post reported.It doesn't stop there: After a clear picture of where an infected person went is established, the South Korean government then publishes that anonymized information on a public website so others can check to see if they have been exposed.
Using smartphone apps to flatten the curve
Unlike China and the US, South Korea never implemented large-scale lockdowns, though it did shut down schools and impose a curfew in some cities.
According to a South Korean government report called "Flattening the curve on COVID-19: The Korean Experience," more restrictive measures weren't needed because the government can easily alert people about whether they've come near someone who tested positive. Officials in the country are constantly updating national and local government websites that track the numbers of cases and residents tested. That way, they can communicate to the public how many people are infected in each geographic area in real-time. Then smartphone apps send people emergency text alerts about spikes in infections in their local region.One specific app sounds an alarm when users get within 100 meters of a place that someone with a confirmed coronavirus diagnosis recently visited. Another helps employees plot the safest routes to and from work that don't intersect with the previous paths of infected individuals.
The tests were free.
If a resident tests positive or is suspected of coming into contact with an infected person, the government then encourages them to download self-quarantining apps that help users monitor their condition. The apps can connect them to a doctor if needed, and they also set off an alarm if the sick user ventures outside their designated quarantine area.
South Korea's February outbreak was controlled within weeksSouth Korea reported its first coronavirus case on January 20 — the same day the US did. At first, case numbers remained low. But in mid-February, a 61-year-old woman attended church services in Daegu. Soon after, she tested positive for the coronavirus, then so did dozens of others. South Korea's coronavirus case count quickly jumped from 29 cases on February 15 to more than 2,900 two weeks later.
But the country quickly implemented large-scale coronavirus testing, which helped
By mid-March, South Korea's epidemic curve had flattened. To date, it has reported about 11,200 coronavirus cases and 264 deaths.Read the original article on Business Insider
