wwwnc.cdc.gov (17.09.2020) The Korea Centers for Disease Control and Prevention (KCDC) classified the severity of COVID-19 into very severe, severe, mild, and asymptomatic (15) (Appendix Table 1). Mild COVID-19 is defined as alert and meeting >1 of the following conditions: <50 years old, >1 underlying conditions, and temperature <38°C with antipyretic drugs. Asymptomatic is defined as a patient who is alert, <50 years old, has no underlying disease, is a nonsmoker, and has a temperature of <37.5°C without antipyretic drugs. Patients classified as severe or very severe were admitted to hospitals; CTCs only accepted patients classified as having mild or asymptomatic COVID-19. Patients with mild COVID-19 met >1 of the following criteria for CTC admission: they did not necessarily require hospitalization; they only required monitoring; they were unable to properly self-isolate (for instance, they had no suitable place to live or lived with persons in a high-risk group); or, as determined by local government, they needed to be admitted to a CTC. Medical staff assessed patients and excluded persons at high-risk for deterioration from CTCs and recommended hospitalization. |
