• What is the criteria for classifying someone as a “contact” (a person who has been in contact with a confirmed case)?


    ○ The criteria is determined based on an exposure assessment conducted by emergency response teams in each city and province.

    ○ The scope of exposure starts two days before the confirmed patient started showing symptoms (for asymptomatic patients, two days before samples were collected), taking into account the symptoms displayed by the confirmed patient, whether the confirmed patient was wearing a mask, and risk level of exposure (location of contact, duration of contact, etc.).
