At 10 am on February 27th, Guangzhou Medical University held a special news briefing on epidemic prevention and control.
The leader of the high-level expert group of the National Health Commission and the director of the National Respiratory Diseases Clinical Medicine Research Center Academician Zhong Nanshan attended the speech and answered questions from reporters.
"Predict the basic control of the epidemic by the end of April"
Zhong Nanshan introduced that in response to the epidemic, there are actually two situations to be dealt with. One is that the disease in Wuhan is extremely serious, and the other is that the infection is very fast in other places.
is different from the general epidemic. The infection situation of new crown pneumonia is higher than SARS. According to our statistics, the RO value of new crown pneumonia is between 2 and 3 (one person infects 2 to 3 people) , indicating that the infection is very fast. The epidemic prediction model must first consider China. first appeared in China, not necessarily originated in China .
Zhong Nanshan said that abroad predicts that my country's epidemic control will be controlled as early as the end of May, but we predict that it will be the end of April. Because has strong national intervention and awareness of group prevention and control, we want to compare!
“China’s new cases of new coronary pneumonia have been less than those of foreign countries.” According to Academician Zhong Nanshan, China’s new cases of new coronary pneumonia have been less than those of foreign countries. The most prominent cases of abroad are South Korea, Iran, and Italy, which have increased very rapidly. Some of 's practices in China may give them some inspiration. Early detection and early isolation are critical. He also expressed the need to strengthen international cooperation. In the past, there was always a little friction with Japan and South Korea. However, supported us in times of crisis, and we will not forget to support them, so he is very willing to participate in regional exchanges, and should communicate in time. , Grasp the development of the epidemic and discover treatment methods.
Academician Zhong Nanshan will also be invited this weekend, will give a video report to the European Respiratory Association, introducing them to China's experience.
"Not enough attention is paid to sudden infectious diseases"
Zhong Nanshan said that everyone was very impressed with the previous SARS, and later did a lot of research, but felt that this was an accidental incident, and many research departments stopped doing it afterwards.
"We have also done research on MERS, and it is the first time in the world to separate and produce a model of MERS. We have been working on it, so we have some preparations. But most of them don’t pay enough attention to sudden infectious diseases, so they didn’t do it. Continuous scientific research, this new disease, my feeling is that I can't do anything about the treatment. I can only treat it with existing medicines based on many principles. In a short time of ten days and twenty days, can It is impossible to develop new drugs. This requires long-term accumulation, which also reflects the problems of our prevention and control system. "
"humans have been infected with coronavirus three times in 20 years"
Zhong Nanshan said that has entered the millennium. It has only been 20 years, but humans have been infected with three times. The first time was SARS virus in 2003, and the second time was MERS (Middle East Respiratory Syndrome) in 2015. This is the third time, the new coronavirus in 2019. . These are all coronaviruses. Therefore, we must strictly prevent and control.
In this regard, he said that it is necessary for to fast wild animals, but the current market situation is to prohibit more than . The cats that Guangdong people like to eat often carry viruses. If they spread to humans, they will get sick. Civet cats are very important reservoirs. Many wild animals on the market carry coronaviruses, and eating them will cause major problems.
“nucleic acid recovery after discharge will generally not be infected again”
For some patients with nucleic acid detection after discharge, Zhong Nanshan said that there are relatively few cases of general influenza. We do not know the condition of this disease. Generally speaking The virus infection process is similar.
If a sufficient amount of antibodies appears in the patient's body, the patient will generally not be infected again! This is the law. As for , there are remnants in its intestinal feces, and whether it will infect other people again, this remains to be seen.
