The new coronavirus is usually detectable about 1 to 3 days after infection.
The incubation period is around 1 to 14 days after infection with the Neo-Crown virus, and most people are able to detect it in around 1 to 3 days. After infection, the virus is already present in the respiratory tract even if there are no physical symptoms during the incubation period, and the infection can be detected by means of a nucleic acid test.
The time it takes for the virus to be detected varies from one infected person to another, and a single nucleic acid test does not always detect infection. Close contacts of a person infected with the new coronavirus should be quarantined as soon as possible and subjected to multiple consecutive new coronavirus nucleic acid tests. The quarantine period should not be less than 14 days and should only be lifted after two consecutive negative NCR tests.
