Requests to those who have been in close contact with a person infected with the new coronavirus

What is a close contact person?

Among those who have been in contact with an infected person during the infectious period (from 2 days before the onset of symptoms to during the recuperation period), those who fall under the following range are considered "close contacts". (From the National Institute of Infectious Diseases "Proactive Epidemiological Survey Implementation Guidelines")


(1) People who have been in contact with each other for more than 15 minutes without taking necessary infection prevention measures (masks, etc.) at a distance where they can touch with their hands (1 meter as a guideline) (depending on individual circumstances such as the surrounding environment and contact status) comprehensively assess the patient's infectivity)
(2) A person who lived with an infected person or had prolonged contact (in a car, an airplane, etc.) (3) A person who examined, nursed, or cared for a patient without appropriate infection protection (4) Respiratory secretions of an infected person Or those who are likely to have come into direct contact with contaminants such as bodily fluids

Waiting period for close contacts

Please refrain from going out for 5 days and observe your health for 7 days, starting from the day after the infected person's onset of symptoms (the day the specimen was collected if there are no symptoms) or the day after infection control was taken, whichever is later. .

If you are not living with an infected person, please refrain from going out for 5 days from the day after your last contact with an infected person and monitor your health for 7 days.

However, if a negative result is confirmed by testing using an antigen qualitative test kit approved by the pharmaceutical affairs on the 2nd and 3rd days of the waiting period (testing at own expense), the waiting period will be lifted from the 3rd day. (Infants are not expected to use an antigen qualitative test kit, so they will have to wait for 5 days.) may ask you to refrain from going out and observe your health for 7 days, so please contact the relevant departments for details).

In this case, there is no need to individually confirm the cancellation decision with the public health center.
