COVID-19 pandemic in South Korea

The ongoing COVID-19 pandemic spread to South Korea on 20 January 2020, when the first case was announced.
Cases.
The number of confirmed cases increased on 19 February by 20, and on 20 February by 58 or 70, giving a total of 346 confirmed cases on 21 February 2020.
Actions.
With the fears of further contamination, mass gatherings in the affected cities were cancelled and a few hundred soldiers in Daegu are in isolation. On 4 February 2020, in order to help prevent the spread of COVID-19, South Korea began denying entry to foreigners traveling from Hubei Province.
Numbers.
By 23 September 2020, South Korea had about 23,216 cases and 388 deaths, and by 9 April 2020, with over 494,711 people having been tested.
Programs.
South Korea created what was thought to be one of the largest and best-organised epidemic control programs in the world, along with Taiwan, Vietnam, and Singapore.
Different actions have been taken to screen the mass population for the virus, and isolate any infected people as well as trace and quarantine those who contacted them, without further lockdown.
The rapid tests taken by South Korea have been successful in limiting the spread of the outbreak, without added a mass quarantine action.
