South Korea is one of the countries with a high number of cases of Coronavirus or COVID-19 with 6,248 infected cases. Due to the rapidly increasing of people being affected by the virus, travel ban to South Korea has been imposing by almost a hundred countries around the world.
As for precaution by the local government of South Korea, its central bank Bank of Korea (BOK) had been quarantining its banknote for two weeks and even burned some of it to lessen the possibility of more outbreaks.
"For all cash coming to the central bank from local banks, the Bank of Korea will keep it in a safe for two weeks, given that the virus usually dies out after nine days," a BOK official told Reuters.

BOK said that they are putting their currency in a high-heat laundering process before releasing it and adding it to the circulation. It is said that the virus dies in high temperature and similar viruses like SARS emerges during cold weather and then dies during the hot season.
South Korean COVID-19 cases are increasing so I think it's a good thing to do to lessen the possibility of spreading the virus. Although by this, the virus won't be totally stopped from spreading but this is a big help especially for countries highly affected by the virus.
