Wu Hao, chief expert of community health in Beijing: 34% of confirmed cases in newly-increased epidemic are not feverish
In the future, there may be a transition from fever monitoring to symptom monitoring
Judging from the current data, 34% of the confirmed cases in newly emerging epidemic outbreaks do not have fever, which means that in the future, it may be necessary to transition from simple fever monitoring to symptom monitoring, and report any uncomfortable symptoms in time. ——Wu Hao
As of July 18, Beijing had 13 consecutive days of "zero new" diagnosed cases of new coronary pneumonia, with only one town left in the middle-risk streets. From one new case on June 11 to zero new on July 6, the accumulated experience and resources for several months allowed Beijing to quickly control the epidemic within 26 days.
Wu Hao, an expert from the Expert Committee on Disease Prevention and Control of the National Health and Health Commission and the chief expert in Beijing community health, said in an interview with the Beijing News on July 18 that the "early detection" played a very important role in the rapid and stable outbreak. This shows that the publicity and education of epidemic prevention in the past six months is effective.
In view of the daily epidemic prevention in the future, Wu Hao believes that in the future, it may be necessary to transition from simple fever monitoring to symptom monitoring, to be prepared for long-term combat with the virus, and to further strengthen the "early detection", which requires everyone "War epidemic". The people must grasp and understand the virus-related knowledge and turn it into action. This Beijing experience reminds us that although the virus is very cunning, if early detection, early report, and early treatment are achieved, the cure rate is very high, and there are no deaths, which can eliminate the panic of the people on the new crown virus .
It is important that the epidemic is quickly and smoothly "early detection"
Beijing News: By the 18th, Beijing had been "zero new" for 13 consecutive days. Looking back, the reason why the epidemic can be stabilized quickly and quickly, what did Beijing do?
Wu Hao: This epidemic can be stabilized so quickly, reflecting the important role of "early detection", which includes several aspects.
The first is the improvement of residents’ own health literacy. After symptoms appear, they can take the initiative to report, seek medical treatment, and take measures, which shows that our publicity and education in the previous six months were effective.
The second is the rapid mobilization of professional technical departments in the early stage of the epidemic. For example, most of the cases were found to be related to the new wholesale market through sampling and flow adjustment. This quickly locked the risk of the epidemic, especially the beef and mutton hall. , Of which professional and technical forces have played a role.
We have also resorted to modern information technology, using big data action trajectories to quickly target close groups and high-risk groups, and conduct early warning, isolation, and control.
Laboratory diagnosis, including nucleic acid testing, is also very important. We have conducted "exhaustive testing" of high-risk groups. At present, more than 11 million tests have been conducted. A group of asymptomatic infected persons and confirmed cases were screened through nucleic acid testing, and hidden and potential "burst points" were dug out. At present, nucleic acid detection is still a very effective method for rapid screening.
Beijing News: In this epidemic, Beijing has not taken measures to completely close the control, but it has successfully controlled the spread of the community. What do you think is the reason?
Wu Hao: Expert research and judgment have played an important role. How to combine epidemic prevention and control with economic and social development as a whole to minimize the impact of epidemic prevention and control on production and life requires scientific research and judgment.
Therefore, we did not conduct large-scale closed control, but divided different risk levels in units of streets. The middle and high-risk street communities were not all closed. Instead, we determined the high-risk communities directly related to the diagnosed cases, so as to be precise Closed control.
Depending on the risk, different methods have been adopted for the control of close-coupled people, some are at home control, some are at the isolation point, and the control time of the isolation point is also different, some are "14+14", some are "14+7".
In addition, the establishment of an efficient collaborative command system is very important for epidemic prevention and control. Experts make judgments and suggestions, and they also need leaders to make decisive decisions and quickly play an organizational mobilization role.
In the early stage of the epidemic, Beijing dispatched a working group to Xinfa District to direct Fengtai to carry out its work. Due to the large number of segregated personnel, Beijing mobilized the city's resources to help Fengtai share the segregated personnel. People's cooperation and participation are also very important. Many closed communities have a large number of resident volunteers.
Generally speaking, the prevention and control of epidemic situations test the ability of social governance, and efficient social governance will definitely shorten the time of epidemic prevention and control.
Be prepared to fight the virus for a long time
The Beijing News: As the epidemic situation in the newly-grown place is stable, the flow of people begins to increase. What should be paid attention to in the next daily epidemic prevention?
Wu Hao: First of all, we must consolidate the good prevention and control experience we have gained in emergency operations, for example, continue to strengthen personal hygiene work, strengthen environmental governance, and prevent the virus from having room to survive. More importantly, it is necessary to prepare for a long-term battle with the virus and further strengthen the "early detection", which requires everyone to be a "war epidemic".
How can we achieve "early discovery"? On the one hand, it is very important for the people to master and understand the virus-related knowledge and turn it into action. This Beijing experience reminds us that although the virus is very cunning, if early detection, early report, and early treatment are achieved, the cure rate is very high, and there are no deaths, which can eliminate the panic of the people on the new crown virus .
On the other hand, it is very important for the unit to play the main responsibility and remind each other among colleagues. After the epidemic has stabilized, there will be more room for personnel exchanges and activities, and people will gradually return to work. Sometimes the person involved does not realize it and needs to be reminded by colleagues and units around him to report and seek medical treatment in time.
It must be noted that from the data we have at present, 34% of the confirmed cases in newly-emerged cluster epidemics are not feverish, which means that in the future we may have to transition from pure fever monitoring to symptom monitoring. As long as there are symptoms of unsuitability, it should be reported in time.
Beijing News: The grassroots community health service center is known as a "healthy gatekeeper". In the epidemic of more than half a year, have the functions of grassroots medical and health institutions been strengthened?
Wu Hao: This new coronary pneumonia epidemic is a great exercise for the grassroots medical and health system. At the same time, it has also brought close contact between grassroots medical personnel and the public. Because Beijing has rich medical resources, people used to choose large hospitals for treatment. Through this epidemic, the public found that primary-level medical institutions are still good, and they can do a lot of things. In the future, they may choose more primary-level medical institutions to visit the nearest hospital.
At the same time, to be prepared for the long-term battle against the virus, we still need the primary medical and health institutions to continue to play a role. For example, if I just said that after the transition from fever monitoring to symptom monitoring, once the symptoms appear, it may be preferred to recommend people to the primary medical institution for medical treatment, which can greatly reduce the number of people gathered, and then the primary medical institution will screen and judge whether it is necessary. Go to a specialist hospital for treatment and investigation.
