“Close contact” means a person who has been in contact with another person/other people who has/have been confirmed to be infected with the COVID-19 (hereinafter referred to “infected person”) for 15 minutes or more and within about 1 meter apart without taking necessary measures to prevent infection, such as wearing a mask, etc., from 2 days before the onset until the first day to be hospitalized, etc.
Therefore, since the close contact person may be infected with the COVID-19, please give attention to the health condition for 14 days after contacting with the infected person (health observation) and refrain from going out unnecessarily.
No matter if the test result turns out to be “negative”, it is not the proof of that you are not infected.
Please follow the instructions of the health center(hokenjo) such as refraining from going out unnecessarily for 14 days after contacting the infected person.
In the prefecture, we investigate the actions of infected people from 2 days before the onset to the day they are hospitalized, etc., and conduct examinations and health observations of those people who corresponded to close contacts.
Close contacts may be infected with the COVID-19, therefore, we have been actively investigating.
In the case that those people who have been confirmed to be infected have one another as close contacts, procedurally, the person who has notified first is referred to the infected person, and another person who has notified later is referred to his/her close contact.
This reference is in the order which the onset notifications were accepted, regardless of the date of infection or the date of onset. Therefore, it does not mean that the close contacts were infected by the infected persons.
