China News Agency, Beijing, July 11 (Xinhua): Since the outbreak of the Beijing Xinfadi wholesale market, there have been no new confirmed cases in Beijing for 5 consecutive days. Wu Zunyou, chief expert in epidemiology of the Chinese Center for Disease Control and Prevention, said in an interview with CCTV on the evening of July 10 that during the outbreak, Beijing’s response provided a very good example for other parts of China and the world.

  "We are thinking about whether Beijing's response can be further shortened." Wu Zunyou said that through analysis, it was found that it could hardly be shortened anymore. Each link is very compact, with almost no delay. The first time to find a case, the first time to take measures to prevent the virus from spreading on a larger scale, Beijing's experience is worth summarizing.

It is very important to seek medical attention and report actively

  "The most important thing is that the treatment of early patients has attracted the attention of the medical system." Wu Zunyou said that if the patient does not go to the doctor for infection, the virus will spread quietly in the family and society. Therefore, it is very important for patients to seek medical treatment and report on their own initiative. We should be grateful for the first case of the epidemic, "Uncle Xicheng".

  He also pointed out that Beijing’s health and disease control departments responded quickly and timely locked the Xinfadi wholesale market, actively detected it, and discovered it early; at the same time, a series of combined punches were taken, one by one, every measure was precise In place.

  It is reported that in less than 22 hours, Beijing judged that the Xinfadi wholesale market beef and mutton comprehensive trading hall bears the first floor as the common risk of the epidemic. Afterwards, a series of measures were taken decisively, including the temporary closure of the Xinfadi wholesale market, the closed management of the surrounding communities of the market, the centralized medical observation of market practitioners, and the active expansion of the nucleic acid detection range, etc., to curb the spread of the epidemic.

Supplementing rheology to early cases

  Where did the new coronavirus that caused the outbreak come from? Wu Zunyou said that finding the source of the virus is very difficult. An outbreak occurred suddenly in Beijing after 56 days, indicating that the virus must have been brought in from outside.

  However, he believes that it is difficult to find out the source of the poison. It is necessary to do work from two aspects, one is goods and the other is people. From a human point of view, a large number of clue investigations and investigations have been done, more and more clues have been excluded, and some new clues are in progress, and supplementary investigations of early cases are being implemented.

  He said that the supplementary survey has to answer two questions: First, they are also engaged in business, some people are infected, some people are not infected, some customers are infected, and some customers are not infected, what is the specific reason. Second, whether it is people or objects that bring the virus in. Can the clues provided by the practitioners and customers of the early onset provide new ideas to carry out the investigation?

When will Beijing adjust the emergency response level

  After the cluster epidemic in the newly issued wholesale market, Beijing quickly changed the emergency response level of public health emergencies from three to two.

  Wu Zunyou said that there have been no new confirmed cases in Beijing in the past few days, and the epidemic has been controlled. Judging from the current situation of prevention and control in Beijing, even if there are sporadic cases, the nature is sporadic cases before the end of the epidemic, which is completely different from the newly added cases in the early stage of the epidemic and "will not pose a threat to society."

  However, Wu Zunyou pointed out that there is currently a high-risk area in Beijing. Only after the high-risk areas are downgraded to medium-risk, it is possible to adjust the level of response.

  He said that observing the epidemic situation in the past period, it is estimated that the high-risk areas may be adjusted to medium-risk in the next week. After the adjustment, the adjustment of the response level may be considered in a short time, which is estimated to be about one week to 10 days. (Finish)
