Entrance procedure
Symptomatic travelers
All travelers entering Korea (both Korean and foreign nationals) are tested if they exhibit fever or respiratory symptom identified at entry screening. Travelers who test positive for COVID-19 are transferred to a hospital or residential treatment center. Korean nationals or foreign nationals on long-term visas who test negative are placed under self-quarantine (14 days, Self-Quarantine Safety Protection App to be installed) and foreign nationals on short-term visas are placed under quarantine at facilities (14 days, Self-Diagnosis App to be installed).
