It is required to collect nasopharyngeal swab for nucleic acid detection during medical observation in isolation, and collect two samples of nasopharyngeal swab at the same time when the isolation is lifted, and use different nucleic acid detection reagents for detection respectively. In principle, the two tests should be carried out by different testing institutions.
Nucleic acid detection was carried out on the second and seventh day after separation. During the period, do a good job of health monitoring, reduce mobility, do a good job of personal protection when going out, and don't participate in party activities.
In addition, domestic provinces and cities have further upgraded and strictly controlled the number of days of entry quarantine.
Shanghai: 14+7
According to the notice issued by the Office of Shanghai Leading Group for Epidemic Prevention and Control on May 4th, Shanghai will continue to carry out community health monitoring for seven days from 0: 00 on May 6th (previously it was "14" or "3+ 1 1").
Six nucleic acid tests were carried out during isolation observation and community health monitoring; For those who focus on research, the frequency of nucleic acid detection should be increased appropriately.
Beijing: 14+7+7
The health management measures for people entering Beijing in Beijing have been increased from "14+7" to "14+7+7", that is, after the expiration of the centralized isolation of 14 days, they will continue to stay in the hospital for observation for 7 days. During the period of health monitoring, they can travel normally, but they can't participate in various group activities. More than 2,600 people entered China through other ports. You need to make up for 7 days of health monitoring after entering Beijing.
Nanjing: 14+ 14
Nanjing implements "14+ 14" health management measures for overseas entry personnel, that is, centralized isolation 14 days, plus home isolation medical observation 14 days.
Hubei: 14+ 14
Implement "14+ 14" health management measures for people entering Hubei. That is, 14 days of centralized isolation medical observation, during which nucleic acid detection and 1 antibody detection were carried out twice; After the expiration of centralized isolation medical observation, home medical observation was carried out for 14 days, during which nucleic acid detection was carried out twice.
Jilin: 14+ 14, 14+7+7
Jilin Province implements "14+ 14" quarantine for those who return from overseas high-risk countries, that is, centralized quarantine at the entry port 14 days, and then continue centralized quarantine after arriving in Jilin 14 days. The overseas returnees from other countries (non-high-risk areas) will be quarantined for "14+7+7" days, that is, after centralized quarantine at the entry port 14 days, they will be quarantined in Jilin for 7 days and then transported back to China for 7 days.
Heilongjiang: 14+ 14
After 14 days of centralized isolation observation and 14 days of home isolation, three nucleic acid tests and one antibody test were completed.
Liaoning: 14+7+7
After centralized isolation 14 days, 7 days of home isolation (centralized isolation for those who do not meet the requirements) and 7 days of community health examination were carried out. During the 14 day centralized isolation, two nucleic acid tests and one antibody test were carried out, and one nucleic acid test was carried out after the expiration.
The same 28-day isolation measures (including "14+ 14" or "14+7+7") are taken in Guizhou, Shanxi, Anhui, Yunnan, Hunan, Henan, Shaanxi, Gansu, Jiangsu and Chongqing. ...
Particularly strict areas, such as Macau, have tightened the epidemic prevention measures for overseas immigrants since May 18, considering that people who have been infected with COVID-19 virus are at risk of recurrence:
The observation period of isolated medicine was extended from 2 1 day to 28 days;
For those who enter from India, Pakistan, Philippines, Nepal or Brazil, the quarantine medical observation period is extended from 28 days to 35 days.
However, some provinces and cities have relaxed their segregation policies.
Zhejiang: 14+7
On March 23rd this year, Zhejiang Province announced that the health management measures for foreigners coming to Zhejiang were changed from "14+7+7" to "14+7". That is, 14 days of centralized isolation plus 7 days of home health observation, and 7 days of daily health monitoring is no longer implemented.
Sichuan: 14
Since March this year, Sichuan Province has implemented centralized isolation 14 days for immigrants, and no more home isolation. During centralized isolation medical observation, nasopharyngeal swabs were collected on 1, 7/and 14, and nucleic acid detection was completed. On 14, at least two reagents were used for parallel verification (in principle, carried out by different detection institutions), and 1 antibody detection was carried out.
In addition, the areas where 2 1 day isolation measures "14+7" are adopted are: Tianjin, Guangzhou, Shenzhen, Shenyang, Dalian and Fujian. ...
Legal basis:
Novel coronavirus prevention and control plan (8th edition) 1. Confirmed cases. After discovery, it should be transported to the designated medical institution for treatment and isolated medical observation within 2 hours. After the case is cured and discharged from hospital, medical observation should be continued 14 days. Nucleic acid reexamination was positive, and clinical manifestations such as fever and cough appeared. CT images show that lung lesions are aggravated, so they should be transferred to designated medical institutions as soon as possible and isolated according to the requirements of confirmed cases. Those who are positive for nucleic acid detection but have no clinical manifestations and CT imaging progress are isolated as asymptomatic infected persons.
2. Suspected cases. After isolated treatment in a single room in a designated medical institution, COVID-19 nucleic acid test was negative for two consecutive times (the sampling time was at least 24 hours apart), and COVID-19 specific antibodies IgM and IgG were still negative 7 days after the onset of -9- disease, so the diagnosis of suspected cases could be ruled out. Serological IgM and IgG are not used as exclusion indexes for those with vaccination history.
3. Asymptomatic infected persons. Centralized isolation medical observation should be carried out in designated medical institutions 14 days. In principle, if the nucleic acid test of samples is negative for two consecutive times (the sampling interval is at least 24 hours), the centralized isolation medical observation can be lifted. If the nucleic acid test is still positive and has no relevant clinical manifestations, it is necessary to continue to concentrate on medical observation. During the observation period, if the nucleic acid test is negative for two consecutive times, the centralized isolation medical observation may be lifted. During the period of centralized isolation medical observation, routine blood examination, CT image examination and antibody detection should be carried out; After meeting the diagnostic criteria, it was corrected as a confirmed case in time. Asymptomatic infected persons who have been released from centralized isolation medical observation will continue to implement home medical observation 14 days and stay at home.
Follow-up visit to designated medical institutions in the second and fourth weeks.
