China News Service, Beijing, May 19. At present, the epidemic prevention and control situation in Beijing is still severe and complicated.
Many citizens have just completed three rounds of nucleic acid testing, and then they have to do three more rounds of nucleic acid testing. Why "three rounds after three rounds"?
After some infected people are cured and discharged from the hospital, they "returned positive" during the home monitoring period. Will the residents of the community be blocked?
Authoritative experts have given answers to these key issues that citizens are concerned about.
Reporter: After the residents participated in the nucleic acid test for 3 consecutive days as required, they immediately received a notice to continue the nucleic acid test for 3 consecutive days. Why do you need to continue the nucleic acid test?
Expert: Nucleic acid testing is an important means to detect the source of infection as soon as possible, control the spread of the epidemic, and assess the risk of the epidemic.
The Omicron strain has the characteristics of fast spread and strong concealment, and it is easy to accelerate the spread of the epidemic with the movement or gathering of people.
The study found that the average incubation period of Omicron virus is 3-4 days. Therefore, based on expert advice, it is proposed to use 3 days as a continuous screening cycle. However, due to the difference in the detoxification time of individual infected persons, coupled with the flow of people, it will increase the spread. Risk, only a single round of nucleic acid testing for 3 consecutive days cannot fully guarantee the screening of hidden viruses at one time. It is necessary to increase the frequency of screening to identify hidden sources of infection in order to block the spread of the virus.
Practice has proved that nucleic acid detection is the most effective, accurate and lowest-cost way to prevent and control the epidemic. Only by scientifically evaluating, dynamically adjusting, optimizing strategies, and making full use of the efficiency of nucleic acid detection can we achieve "early detection", "fast control", Epidemic risks and social costs are minimized.
Here, I also hope that the general public will understand, support, and cooperate with the regional nucleic acid screening. When participating in nucleic acid testing, obey the arrangement, line up in an orderly manner, and work with us to overcome the difficulties and fight the epidemic together, so as to achieve an early social cleanup. Zero contribution of their own strength.
Reporter: According to the ninth edition of the diagnosis and treatment plan, the standard for discharge (cabin) is that the nucleic acid detection Ct value of two consecutive 24-hour intervals is greater than or equal to 35.
On the 4th and 7th day of home health monitoring for discharged (cabin) personnel, a nucleic acid test is required. If the detected Ct value is less than 35, which is the so-called "Fuyang", what should I do?
Is the building where it is located closed?
Expert: Relevant domestic studies have shown that when the nucleic acid Ct value of the convalescent infected person is ≥35, the virus cannot be isolated from the sample, and the close contact is not found to be infected. Therefore, the "New Coronavirus Virus" issued by the National Health and Health Commission The Pneumonia Diagnosis and Treatment Plan (Trial Version 9) has adjusted the isolation management and discharge criteria (Ct value ≥ 35 or negative can be released from isolation, Ct value ≥ 35 or negative and body temperature has returned to normal for more than 3 days, and respiratory symptoms have improved significantly. , Pulmonary imaging showed significant improvement of acute exudative lesions and can be discharged).
In order to strengthen the management of people who have been released from isolation or discharged, we have clarified the requirements for the transfer and discharge of patients infected with the new coronavirus. Discharged patients will continue to undergo 7-day home health monitoring, and nucleic acid testing will be conducted on the 4th and 7th days.
At the same time, it is clear that the nucleic acid re-examination on the 4th and 7th days of discharged patients shall be made by the community (village) where they are located and the district health and health department, and the nucleic acid shall be carried out by arranging the designated institution for on-site sampling or closed-loop transfer to the designated medical institution in the jurisdiction for sampling. Testing should not be mixed with social screening to avoid misjudgment of results.
Once it is found that the Ct value of the discharged patient is less than 35, the patient will be transferred to a designated hospital or makeshift hospital for isolation management.
So far, there is no evidence that Fuyang patients have re-infected others. As long as the environment is disinfected and the building is kept clean and hygienic, no closure and control measures are required for the building where the Fuyang case is located.
