Centralized isolation management for mild cases< /span>
is a scientific policy
national health Lu Hongzhou, a member of the Committee of Experts on Disease Prevention and Control, and President of Shenzhen Third People’s Hospital, explained that this is a scientific policy. “Mild people are a source of infection. If they don’t go to isolation, it will be passed on to their family members and the society. Therefore, it is necessary to concentrate in one place, similar to a makeshift hospital, and wait until the acute period, such as 7 to 10 days later, < /span>It’s scientific to go back to society without being contagious.”
Zhang Wenhong, director of the National Medical Center for Infectious Diseases and head of the Shanghai New Coronary Pneumonia Medical Treatment Expert Group, said that for the management of mild patients, the plan further simplifies the treatment, and the focus is on the treatment of the disease. observation. As the prevalence of Omicron has become the current mainstream infection strain, the patients with Omicron variant strains are mainly asymptomatic infections and mild cases, and the demand for clinical specific treatment is significantly reduced, and more symptomatic treatment is required. Can be observed with the condition. So, at the isolation point with certain medical conditions, the isolation and basic medical needs of the infected person can be completed. At the same time, it can release a large number of medical resources of designated hospitals.
Add antigen detection
< strong>Improve the ability of early detection of cases
The new version of the diagnosis and treatment plan optimizes the procedures for case discovery and reporting. On the basis of nucleic acid detection, antigen detection is added as a supplement to further improve the ability of early detection of cases. At the same time, the efficiency of diagnosing or excluding suspected cases is improved, and those with positive antigen test results are required to undergo nucleic acid testing immediately or closed-loop transfer to a qualified higher-level medical institution for nucleic acid testing.
Li Jinming, deputy director of the National Health Commission’s Clinical Laboratory Center, emphasized that nucleic acid testing has always been a basis for us to determine the new crown infection, a “gold standard” . So antigen detection cannot replace nucleic acid detection. When the antigen test is positive, the nucleic acid test must be used for confirmation.
Adjustment of release-isolation management and discharge standards
Strive for patients to get out of isolation earlier and faster
Release isolation management and The Ct value of the discharge standard was also adjusted accordingly, from 40 in the past to 35 in the international standard. When the nucleic acid Ct value is ≥35, the virus cannot be isolated from the samples of infected persons in the convalescent period, and the close contacts are not found to be infected.
Lu Hongzhou’s analysis: “The Ct value is simply the number of times the virus is amplified. If the Ct value exceeds 30, the virus will be able to expand it. It was added, but it was not a live virus. We did cell experiments. If it could not infect cells, it proved to be a dead virus. We also did the whole gene sequence of the virus. It was just a fragment of the virus, which proved to be a dead virus , so this is more scientific, and there is no need to increase the isolation time of patients.” Earlier and more accurate safe discharge standards have been established to strive for patients to be released from isolation earlier and faster. Our understanding of Omicron is also gradually deepening. International studies have found that it has also been carefully verified by Chinese experts.After the nucleic acid reaches a certain level, the infectious virus can no longer be detected, and it is almost non-infectious. Therefore, our nucleic acid positivity judgment criteria, from stricter criteria to the current international synchronization, have reduced the standard hospital stay. More patients can be discharged early, which will greatly relieve the pressure on our medical resources.
7-day home health monitoring after discharge
Do not cause a run on isolation resources
The new version of the diagnosis and treatment plan will “continue to continue 14 after discharge “Day isolation management and health monitoring” was revised to “Continue 7-day home health monitoring after release of isolation management or discharge from hospital”.
Zhang Wenhong said that the standard of home health monitoring for 7 days after discharge from the hospital has been explained earlier, which is based on medical evidence, which not only allows infected persons Return to normal life as soon as possible, reduce the economic burden during the isolation period, and also save the corresponding isolation room and other social resources, so that the ability of the entire society to respond to the epidemic will be further improved, and the isolation resources will not be depleted. run. Based on changes in diagnostic criteria, the probability of re-positive after shortening the isolation period will be very low; according to our research, even if re-positive, the nucleic acid level is already very low, basically no Because Fuyang caused secondary transmission.
