Should COVID-19 be quarantined when he goes to other provinces 28 days after his illness is unsealed?

Twenty-eight days after the epidemic was unsealed, there was no need to go to other provinces for isolation.

Due to its own characteristics, there are many ways of transmission in COVID-19. Besides respiratory droplets and contact, long-term exposure to high-concentration aerosols in a relatively closed environment may also spread through aerosols. And the incubation period is long, the average incubation period of the virus is about 7 to 14 days, and there are asymptomatic communicators. In other words, if no infected person is found, there will be nearly 7 to 14 days to spread the virus without implementing the quarantine policy. Meanwhile, the longest incubation period in COVID-19 is 14 days. If a region has zero growth, it should be observed for two 14 days, which is 28 days. Only when there is zero growth in new cases in 28 days can we be 100% assured. When the number of confirmed cases, suspected cases and previously suspected cases turns to zero, all close contacts will be released from isolation, and there is no need for isolation when entering or leaving the country.

The substance of nucleic acid detection is the nucleic acid of virus. Nucleic acid detection is to determine whether the patient is infected by COVID-19 by detecting whether there is nucleic acid of foreign invasive virus in respiratory tract samples, blood or feces. Therefore, once the nucleic acid is detected to be positive, it can be proved that there is a virus in the patient.

Isolation is the epidemic prevention policy during the epidemic in COVID-19. The information of entry-related personnel was promptly pushed to the epidemic prevention and control headquarters of the destination for centralized isolation and nucleic acid detection 14 days.
