During this period, nasopharyngeal swabs were collected on the 6th and 7th days to carry out nucleic acid testing (sampling time is at least 24 hours apart). If the Ct values ​​of the N gene and ORF genes in the two nucleic acid tests are ≥35 (fluorescence quantitative PCR detection method, the limit value is 40, the same below), or the test is negative (fluorescence quantitative PCR detection method, the limit value is less than 35), centralized isolation and medical observation in the temporary hospital can be released.

32. How should close contacts of people with re-positive positive be investigated and controlled?

Answer: After the previous infected person was discharged from the hospital (cabin), the nucleic acid test of the respiratory tract specimen was positive. If there are no symptoms and signs and the nucleic acid test Ct value ≥35, the close contacts will no longer be managed and judged; if the nucleic acid test Ct value <35,>Ct value , etc. If there is a risk of transmission, it will be managed as the infected person. If there is a frequent contact with him, the close contacts of close contacts will not be judged; if there is no risk of transmission, the close contacts will no longer be managed and judged. If there are clinical manifestations such as fever and cough, or if CT imaging shows that the lung lesions are worsened, they should be transferred to a designated medical institution immediately and classified management and treatment should be carried out according to the condition.
