How long COVID-19 infected people should be quarantined depends on the patient's condition and treatment. The isolation time of patients is different, such as mild patients and asymptomatic infected people, which may be relatively short or may take about 2~3 weeks. Only when their clinical symptoms are relieved or disappeared, and COVID-19 nucleic acid is negative twice in a row, can they be discharged from the isolation hospital. However, for severe and critically ill patients, the isolation time needs to be significantly extended. Most patients need isolation treatment for about 1 month, or even longer.

According to the fifth trial version of the notice, the source of infection in novel coronavirus is mainly patients infected by novel coronavirus. But the newcomers are asymptomatic infected people, and they may also become the source of infection. An asymptomatic infected person like this definitely needs isolation. During the isolation period, the body temperature was observed, and there were still some manifestations. If you have elevated body temperature or some cough symptoms, you need to go to the hospital to do some related tests to further clarify. Therefore, according to the longest incubation period, the isolation period should be 14 days for those infected in COVID-19.
