Testing is central, early detection of the virus minimizes its further spread and allows rapid treatment of the sick - said the head of the South Korean Ministry of Foreign Affairs Kang Gyung Hua. He believes effective management and tests are key to our very low mortality rate. South Korea’s health and public administration system was able to quickly protect the population from COVID-19 without the imposition of emergency measures. The adviser to the Swedish government and the Secretary-General of the World Health Organization, Yuhan Gizeke, told the RBC in an interview on May 5, 2020 that the authorities of the country relied on two measures in the fight against coronavirus whose benefit has scientific justification. First, we need to wash our hands, which we’ve known for 150 years. Second, social distance should be respected, that is, not to get too close to other people. Until May 5, 2020, Sweden recorded only 23216 cases of coronavirus infection.
