The reason for the 14-day quarantine is that the incubation period of the virus is usually within 14 days, and a 14-day quarantine can minimize the spread of the virus. After infection, the incubation period of Neocoronavirus is around 1 to 14 days, with the majority of the population developing the disease in around 3 to 7 days. However, in order to maximize the limitation of the transmission of the new coronavirus, it is necessary to isolate for 14 days, in order to avoid the isolation time is too short still in the incubation period of the virus, resulting in the spread of the new coronavirus infection. Currently, people who need to be quarantined mainly include close contacts of neocoronavirus-infected people and people in medium- to high-risk areas, and multiple nucleic acid tests need to be performed during the quarantine period. The quarantine can be lifted after the quarantine is completed and the nucleic acid tests are all negative during the quarantine period and there are no symptoms associated with neocoronavirus infection.
