What is a close contact person?

A “close contact person” is a person who has tested positive for COVID-19 and is within the infectious period (between 2 days before the onset of symptoms (or 2 days before the specimen collection date if the patient is asymptomatic) until the end of medical treatment). In addition, it is a person who has a high possibility of being infected due to close contact or long-term contact.

Those who lived together with a patient (confirmed case) or had contact for a long time (including in a car, airplane, etc.)
Those who examined, nursed, or cared for a patient (confirmed case) without appropriate infection protection
High possibility of direct contact with contaminants such as airway secretions or bodily fluids of the patient (confirmed case)
Others: Contact with a patient (confirmed case) for 15 minutes or more at a distance that can be touched by hand (1 m as a guideline) without necessary infection prevention measures (individual circumstances such as surrounding environment and contact status comprehensively judge the patient's infectivity based on the situation).
