At 21:00 on February 3, Hubei Province held the thirteenth routine conference on epidemic prevention and control to report new progress in prevention and control. Experts from the National Health and Health Commission attended and responded to social concerns around the prevention and treatment of the epidemic.
Point 1: The virus is transmitted mainly through droplets and contact. To strengthen hand washing protection, no cases of fecal-oral transmission have been found.

△ Jiang Rongmeng, a member of the front panel of the National Health Commission
Concern 1: How long can the virus survive in the air? How can fecal-oral transmission be controlled?
Jiang Rongmeng, a member of the expert group in front of the National Health and Health Commission: First, the virus was transmitted through droplets and contact. Generally speaking, droplets spread through the air after coughing or sneezing. The distance of spread is about one meter, at most two meters, so it will settle soon after coming out of the human body, so it does not It will float in the air. In this sense, it will not be virus in the air, so there is no question of how long the virus will survive in the air. I just mentioned that droplets can settle on the surface of objects. It can survive for several hours on these smooth surfaces. If the temperature and humidity are appropriate, they may survive for several days, such as twenty degrees. It is particularly suitable in air-conditioning environments. % To 50%, some studies have found that these coronaviruses may survive up to 5 days in the past.
Although the nucleic acid of the virus has been found in the stool of some patients, no virus has been isolated at present, and further conditions need to be observed. Even if there is a virus, transmission through the feces-to-mouth has not been confirmed. What we call fecal-oral is fecal contamination of water or food, which causes people to drink this water or eat food and cause transmission. This is called fecal-oral transmission. At present we have not found this way. Transmitted cases.
Point 2: Coronavirus is a single-stranded virus with a low probability of mutation. No evidence of virus mutation has been found.

△ Qiu Haibo, member of the front panel of the National Health Commission
Concern 2: How strong is the human body's resistance to the new coronavirus and its ability to heal itself, and will the virus mutate in the spread of the population?
Qiu Haibo, a member of the front panel of the National Health and Medical Commission: As far as the new coronavirus is concerned, it is actually generally susceptible to humans. However, from another aspect, it does not mean that because everyone is susceptible, everyone is infected and everyone is sick. Some people who come into contact with the virus may have several different reactions. One is that he has enough resistance, and he clears the virus himself. The second case may be that the virus can reproduce in the upper respiratory tract, but he has no symptoms, such as asymptomatic infections mentioned by reporters. Of course, there may be many patients who are mild patients, and some are relatively few. Only when the patient becomes severe or critically ill. Only a few abnormal reactions or large numbers of viruses can develop into severe or critical illness.
The mutation of these viruses, like the influenza virus, is known to be relatively easy to mutate, but the coronavirus is a single-stranded RNA virus, which is relatively stable. That is, although it may mutate, it is similar to the influenza virus. In comparison, its mutation probability is still low. In terms of influenza virus, if mutation occurs every year or at least several months, the probability of coronavirus mutation is relatively low.
Point 3: Avoiding the development of critically ill patients into critically ill patients is the key difficulty of treatment.
Concern 3: What are the difficulties in treating severe and critical cases?
Qiu Haibo, a member of the expert group in front of the National Health and Health Commission: How to reduce the mortality rate and reduce the progression of patients to severe and critical illness is the key and focus of our current medical care. We know several recent difficulties or problems. The first is that when it develops from a common or mild type to a severe one, it often takes a long time and the symptoms are not so strong. After this time, the patient's condition may develop into a severe one. This is our first difficulty.
Secondly, as a viral infection, antiviral therapy should be the key to it, but there is currently no means to say that antiviral therapy has been proven to be effective, but we do not prove that there is no antiviral therapy at present. Cannot be treated.
The third is the treatment of patients with respiratory failure. The sign that the patient develops into a severe condition is that the patient has respiratory failure, which is called developing into a severe or critical condition. Because the patient's course of illness is often slower when entering the severe stage, and when the severe stage occurs, some patients behave less typical and manifest as hypoxemia, so early detection of hypoxemia has already given him oxygen earlier. Treatment, to prevent critically ill patients from becoming a critical illness, this is a very important key for our treatment.
The fourth difficulty is that the organ failure caused by such a viral infection is more related to inflammatory immunity, so we are also exploring the perspective of inflammation and immunity.
Point 4: Rehabilitated patients develop antibodies to the new coronavirus, which can protect them from reinfection for a period of time. The virus will be closely monitored for mutations.
Concern 4: For mild and severe patients after discharge, are these people still infectious, will they be infected with coronavirus again?
Qiu Haibo, a member of the front panel of the National Health and Medical Commission: Now more and more patients with mild, severe or critical illness are discharged from hospitals. Whether such patients are infectious after being discharged, at least in our years of research or clinical experience See, the patients in the rehabilitation period are not infectious, or the discharged patients are not infectious. We have undergone two nucleic acid tests for these patients, that is, the body temperature is normal for three days, and the nucleic acid test is performed twice a day. Negative, he basically has no virus replication, so we will let him be discharged from such patients. Because such a patient produces antibodies, he is not poisonous on one side, and the second pair of viruses has antibodies. Therefore, after such a patient is discharged, where does his infectivity come from? .
We know that as a viral disease, in fact, he will basically produce antibodies after one or two weeks, especially after two or three weeks. After the rehabilitation patient has produced anti-virus antibodies, he will at least have a period of time. With the presence of antibodies, and with a certain low level, he can defend against the infection of new coronaviruses. So at least from the research of coronaviruses, we can see that although this antibody is not a lifetime, but at least six months or longer The time is low enough, that is to say, no new infection of this new type of coronavirus will occur in half a year or more. Of course, some people say what to do if the virus mutates? Mutation is indeed possible, but the problem of mutation has been mentioned earlier. At least from the current research and observation or experience, the possibility of mutation in a short period of time is very small, and we have not seen the virus. Mutation, and at the same time, the situation of this virus mutation is being closely monitored.
Point 5: There is currently no suitable medicine to prevent pneumonia from a new coronavirus infection. In order to avoid infection, you need to increase your resistance, and do not advocate taking medicine if you are not sick.

△ Zhang Boli, a member of the expert group in front of the National Health Commission
Concern 5: During the epidemic prevention and control, what medicines should be kept in the residents' homes?
Zhang Boli, a member of the expert group in front of the National Health and Health Commission: There are two concepts of what medicines to store and what medicines to take at home. We do not advocate taking medicines for people who are not sick. Because there is no suitable medicine to prevent it, we say that Chinese medicine is a symptomatic treatment. Traditional Chinese medicine treatment does not target the virus. It is more about regulating the immune state of the body. In fact, we have this disease as a result of a game between the virus and the human body's immunity. Often, the virus wins the disease, so it is not easy to improve the resistance Being infected, but it is not advisable for everyone to take Chinese medicine to prevent it. This makes no sense.
Prepare small medicines at home, such as Lianhua Qingwen, antiviral oral solution, Yinqiao detoxification tablets, Huoxiangzhengqi, etc. These are commonly used medicines, which have certain effects on common colds and flu. If you prepare these The medicine is still okay.
Point 6: The overall infection situation in children is relatively light, which does not mean that children are not susceptible. Most cases of childhood infections are caused by family gatherings.
Concern 6: Cases of children's infection appear in various places. What is the difference between children's treatment and adults' treatment?
Jiang Rongmeng, a member of the expert group in front of the National Health and Health Commission: Through analysis of the national case treatment report, there are now cases of children in various places, the smallest being a few months. Generally speaking, children are also vulnerable groups, but From the current point of view, children are not severely ill and there are no deaths. In comparison, the cases of childhood infections are relatively light, and many of them are found in family gatherings. For example, there is an adult at home or a parent has a plan and is sick After being diagnosed, the child has some contact. Through this screening, more are found in this way, so the overall infection of the child will be lighter in the future, but it does not mean that the child is not susceptible. Schools will start soon in the future. Or it is the gathering of the crowd, and what kind of future progress of children's infection cases need to be further observed.
From the perspective of treatment, everyone also saw that the National Children's Center also released a diagnosis and treatment plan for children with new coronavirus infection pneumonia. This plan is slightly different from adults, but I looked at it, and it is still symptomatic. Focusing on supportive treatment, or helping patients recover from the disease as soon as possible, this is a brief explanation for everyone.
