China News Service, May 8, according to the Ministry of Foreign Affairs' "Consular Express" WeChat public account, a few days ago, the Ministry of Foreign Affairs and the National Health and Health Commission invited the Chinese Academy of Engineering Zhong Nanshan and China in the United States, Russia, South Korea, Australia, Canada, Algeria International students are connected by video to teach the epidemic prevention and epidemic prevention knowledge. The video is synchronously live broadcasted through the official accounts of CCTV News clients and CCTV News on Weibo, Kuaishou, Douyin, Toutiao and other network-wide platforms.
"Four early" is the key to avoid most infections
According to Zhong Nanshan, the infectivity of the new Pneumococcal pneumonia virus is unexpected. From the perspective of infectiousness index, the general flu is 1, SARS is close to 2, the Middle East respiratory syndrome is 1.5, and the new coronary pneumonia is 3.
Zhong Nanshan said that China's epidemic resistance is characterized by "four early days." Early protection, early detection, early diagnosis, early isolation. "Early protection", the most important thing is self-protection, including keeping distance from others, wearing masks, etc .; early detection, if you feel uncomfortable, go to the doctor; early diagnosis, early isolation, China has community joint defense and joint control, from all aspects of supervision , Remind each other to help.
New Coronary Pneumonia is mainly infected through droplets and contact. As long as these are avoided, most infections can be avoided.
Zhong Nanshan said that it was observed that patients with new coronary pneumonia recovered well after being discharged from hospital. Those without basic diseases recover quickly. Even some basic diseases are better than SARS. 17 years ago, SARS patients still had pulmonary fibrosis six months to a year later, and patients with new coronary pneumonia had pulmonary fibrosis that was not very serious and seemed reversible, so the sequelae were not large.
What to do if you experience discomfort
Zhong Nanshan said that the symptoms of New Coronary Pneumonia are similar to those of influenza, such as general malaise, fever, nasal congestion, light cough, etc., especially fatigue. Not everyone with new coronary pneumonia has a fever, and this is also the case with influenza patients, so it is difficult to confirm the diagnosis simply by symptoms and without testing. Cough is a common symptom of many diseases. Dry cough is generally a symptom of acute bronchitis, not the first symptom of flu. Therefore, do not take dry cough as the only consideration, and should analyze more.
If you need to do nucleic acid testing, Zhong Nanshan recommends overseas students to go to the hospital outpatient clinic to do it, because the requirements for nucleic acid testing are relatively high, it is impossible to do it at home. If the test result is positive, there is no need to panic, and cooperate with the treatment.
Zhong Nanshan reminded overseas students that once they have a slight fever, they should pay attention to it, drink plenty of water, and eat some medicines brought from China, such as Baifuning, ibuprofen, and Lianhuaqingwen capsules.
He specifically mentioned that just after an experiment, there is sufficient evidence to prove that Lianhua Qingwen Capsule has some inhibitory effect on the virus, and its advantage is that it has a good repair effect on the cell damage and inflammation caused by the virus. More than 80% of the patients are patients with ordinary new coronary pneumonia. Lianhua Qingwen Capsule is more suitable for patients with ordinary new coronary pneumonia.
There are four cases of asymptomatic infection
Zhong Nanshan said that the so-called asymptomatic infected people actually have several situations:
The first type is the prodromal period, or incubation period, usually 3 to 7 days. There are no symptoms during this time, but he has been infected. After 3 to 7 days, he will have fever, cough, and fatigue.
The second kind, in fact, he has some discomforts, such as feeling tired, very tired, wanting to sleep, muscle aches, and his nose and throat are not very comfortable. He tested positive for nucleic acid. In fact, he belongs to an infected person with very mild symptoms, and a lot of people in this case also account for it.
The third is that the nucleic acid test is positive, but there is no symptom. After a period of time, he still has no symptoms. In mainland China, the nucleic acid test and serum antibody test are generally performed on people in this situation. If the second nucleic acid test becomes negative and the antibody is negative, he is not a patient with new coronary pneumonia at all. If the second time is still positive, he is asymptomatic.
The fourth kind, very individual and a few people, the nucleic acid test is positive, after many nucleic acid tests are positive, no antibody is produced, we call these people "virus carriers."
How to protect and relieve psychological pressure
Zhong Nanshan suggested: First, wear a mask and do a good job of protection. We know that viruses must be attached to something in order to spread, the most prominent is spread through droplets. Wearing a mask is very important, not everyone. In the past, many foreigners took a different view of the Chinese wearing masks. Now, some people who once opposed us wearing masks have also begun to wear masks. It is our correct practices that have driven them.
Second, if multiple people live together, pay attention to disinfection and hand washing in shared toilets, kitchens and other public spaces.
Zhong Nanshan said that in general, the virus has a poor survival rate and activity rate under high temperature environment. The high temperature in summer is not good for virus activity. However, the ultraviolet rays in nature are not strong enough to be disinfected. He mentioned that mosquito bites can infect many diseases, such as malaria and dengue fever, which are more common in Africa. But so far, there is no evidence that the new coronavirus can spread through mosquitoes.
Some international students asked that the psychological pressure of international students under the epidemic situation is generally very large. How to relieve psychological pressure? Zhong Nanshan recalled his experience of studying in the UK 41 years ago. At that time, he also felt lonely and depressed. The subject work was very heavy and the pressure was very great. Now in the epidemic situation, he particularly understands the feelings of foreign students and encourages them to treat the epidemic as a test of their own psychology, not only to do physical protection, but also psychological protection. We must persist in our studies and temper our willpower.
