Recently, some patients discharged from the hospital have been tested for nucleic acid positive. Are they contagious? How effective is the plasma treatment for rehabilitated patients? With the acceleration of the country's resumption of work and production, how to prevent the occurrence of cluster epidemics?
On February 28, the State Council's joint prevention and control mechanism held a press conference to introduce the prevention and control and treatment of New Coronary Pneumonia in terms of critical care, epidemic prevention and control, scientific and technological applications, and disease characteristics.
On February 28, the State Council's joint prevention and control mechanism held a press conference.
The prevention and control situation is positive, and the number of newly confirmed cases appears for the first time.
Mi Feng, spokesperson of the National Health Commission and deputy director of the Department of Publicity:
On February 27, in other provinces except Hubei and other cities in Hubei except Wuhan, the number of newly diagnosed cases of new crown pneumonia fell to the single position for the first time, and the situation of prevention and control was positive. In the next step, we must continue to do a good job in community prevention and control and medical treatment, actively respond to them, take strict precautions, and make every effort to prevent the epidemic from rebounding.
No reinfection occurred in discharged patients
Guo Yanhong, Supervisor, Medical Administration and Hospital Administration, National Health and Medical Commission:
Some provinces reported that the nucleic acid test turned positive in discharged patients. We organized experts to conduct research and strengthened the continuous monitoring of these cases. It was found that there was no re-infection in these patients, and some patients turned to test again. negative. The pathogenic mechanism and characteristics of neocoronary pneumonia need to be deepened. 14 days of medical observation should be performed for discharged patients, and follow-up health monitoring and guidance should be strengthened.
Droplets and close contact remain the main propagation path
Wu Yuanbin, Director of the Department of Social Development Science and Technology of the Ministry of Science and Technology:
So far, research findings have shown that respiratory droplets and close contact transmission are still the main routes of transmission of the new crown virus. During the research, some teams also detected the new crown virus from stool samples of patients with new coronary pneumonia, which suggests that fecal-oral transmission is risky, but further research is needed to confirm the transmission capacity and conditions.

The average person has little risk of aerosol infection
Wu Yuanbin, Director of the Department of Social Development Science and Technology of the Ministry of Science and Technology:
Aiming at the problem of aerosol transmission, the Institute of Experimental Animals of the Chinese Academy of Medical Sciences has also conducted corresponding transmission experiments, suggesting that aerosol transmission must meet the three conditions of closed space, long time and high concentration of virus at the same time. The possibility of sol transmission. For ordinary people, the possibility of transmission in a well-ventilated daily life environment is very small, and there is almost no risk of aerosol infection.
Plasma treatment achieved better results
Guo Yanhong, Supervisor, Medical Administration and Hospital Administration, National Health and Medical Commission:
A large number of clinical research practices have proven that the plasma of neocrown pneumonia recoverers can neutralize neocrown virus through specific antibodies. During the treatment of recovered patients with plasma, relatively good results have been achieved, and its safety and effectiveness have been obtained. accepted. As of now, 544 person-time plasmas have been collected nationwide for clinical treatment of 245 patients. During the clinical treatment of patients, according to the monitoring of a total of 157 patients for more than 48 hours, 91 of them were clinical Indicators and symptoms improved.
Severe patients can also be cured well by intensifying treatment
Guo Yanhong, Supervisor, Medical Administration and Hospital Administration, National Health and Medical Commission:
Currently 36,000 cured patients have been discharged, accounting for 45.9% of the total confirmed cases. At present, more than 8,400 cases have been analyzed: in clinical classification, the proportion of light and common types is 90.8%, the proportion of heavy types is 7.2%, and the proportion of critical illnesses is 2%. From the perspective of complications, of the 8,000 or more cured patients, 1133 had more than one basic disease, accounting for 13.5%, and 242 had more than two basic diseases, accounting for 2.8%. Patients with underlying diseases, even severe patients, can be cured well by intensifying treatment. In terms of clinical diagnosis and treatment, 85% use antiviral therapy, and nearly 40% of patients have received integrated Chinese and western medicine.

A small number of mild cases have progressed abruptly and the cause is not particularly clear
Wang Guiqiang, Director of Department of Infectious Diseases, Peking University First Hospital:
There is also a feature of neocoronavirus infection. A small number of light cases have made sudden and sudden progress. At present, the cause is not particularly clear, and it may be related to a severe storm of inflammatory factors. Therefore, we emphasize that the treatment of light cases should not be taken lightly, and all patients should be diagnosed, treated, and intervened early to avoid the risk of progressing to severe cases.
Passing the barrier to prevent mild to severe illness
Guo Yanhong, Supervisor, Medical Administration and Hospital Administration, National Health and Medical Commission:
Throughout the medical treatment process, the treatment of mild patients is very important. Advancing the threshold is to implement early intervention measures to strengthen the early treatment of mild diseases, while reducing the progress from mild to severe diseases as much as possible during treatment, and greatly improving the cure rate. In order to strengthen medical treatment, the "four early" was implemented in light management, and one case was detected and one case was diagnosed and one case was treated, so that patients could enter the treatment process as soon as possible. In this way, on the one hand, early treatment can be accepted, early treatment and early treatment can improve the cure rate, and on the other hand, it can reduce and prevent the spread of patients in the family and the community.

Resumption of work and production: prevention and control must be done "four mornings"
Cui Gang, Level 2 Inspector, National Health and Health Commission, CDC:
Regarding the localized epidemic situation after resumption and resumption of production, the National Health and Health Commission issued an emergency notice to further improve the prevention and control of the epidemic situation through the joint prevention and control mechanism. Control measures are put in place, especially the "four early": early detection, early reporting, early isolation, and early treatment are the top priorities of comprehensive prevention and control; after the work is resumed, the existing measures must be implemented , Including daily temperature testing, health monitoring, etc .; if suspicious cases are found, report them in a timely manner.
Some people get together? Don't relax your vigilance
Cui Gang, Level 2 Inspector, National Health and Health Commission, CDC:
Before the epidemic situation is under complete control, scientific prevention and control must be carried out, precision prevention and control must be implemented, and grading and zoning must be implemented. Judging from the number of outbreaks in recent days, the situation of prevention and control continues to improve. On the other hand, the situation in Wuhan, Hubei, is still severe. Other provinces should not only consolidate the previous results, but also prevent the epidemic from rebounding, and implement the zoning prevention and control work. New coronavirus pneumonia is a new type of respiratory disease that is generally susceptible to the crowd. At this stage, do not relax your vigilance and continue to do a good job of personal protection.
What medicines can improve immunity and prevent infection?
Wang Guiqiang, Director of Department of Infectious Diseases, Peking University First Hospital:
It is very important to maintain a good immune state and defend against viral and microbial infections, but there are no specific drugs that can actually increase immunity. The public is advised not to blindly take a variety of health products and various drugs, because there may be the risk of drug-induced injuries, or to improve the overall immune level through a balanced diet, good mentality, and appropriate exercise.
