How to calculate the isolation 14 days during the COVID-19 epidemic?

Recently, the number of asymptomatic infections in Shanghai has reached more than 20,000 a day, which is somewhat shocking. Millions of people become secret recipients or sub-secret recipients. So do you know the latest sub-dense connector isolation regulations in 2022? Is there anyone who doesn't need isolation for 14 days?

The latest sub-secret connector isolation regulations in 2022 The latest sub-secret connector isolation regulations in 2022 are as follows:

The "7+7" isolation policy will be implemented for sub-secret personnel, that is, sub-secret personnel need to be isolated for 7 days+7 days at home, totaling 14 days. The period of centralized isolation shall be calculated from the date of the last contact between the sub-close contact personnel and the close contact personnel.

If the last contact date between sub-close contact personnel and close contact personnel is not more than 7 days, the remaining days of centralized isolation are generally completed in the form of missing a few days and making up a few days, and then transferred to home isolation. If the last contact between the sub-secret contact personnel and the secret contact personnel has been more than 7 days, the remaining days of home isolation can be completed without centralized isolation.

For example, Zhang San is a close contact. After traffic adjustment, it was found that Wang Wu had contact with Zhang San three days ago, so Wang Wu needed to be isolated for four days and isolated at home for seven days. Li Si had contact with Zhang San eight days ago, so Li Si only needs to be isolated at home for six days.
