Original title: Zhong Nanshan’s video connection with foreign students Answers “epidemic” problem for international students: disagrees with “group immunization”
The new global epidemic of coronary pneumonia continues to spread. How can international students studying abroad face multiple pressures, such as the epidemic, the closure of the city and the suspension of classes? If symptoms such as cough and fever are found, how to do a self-test? In the absence of medical conditions, how can mild patients perform effective self-treatment at home?
May 4th is Youth Day on May 4th. At 8:00 p.m., the Foreign Ministry and the National Health and Welfare Commission jointly invited academic Zhong Nanshan of the Chinese Academy of Engineering to connect with foreign students to answer the “epidemic” question for students international.
“Early Four” is the key to avoiding most infections
During the live broadcast, representatives of international students in New York, Canada, Toronto, Korea, Seoul, South Korea, Moscow, Russia and Algeria, the capital of Algeria and other places in the world, interacted with academic Zhong Nanshan on issues related to the prevention of epidemics.
Zhong Nanshan said that for China, one of the main characteristics is “four principles”, that is, early protection, early detection, early diagnosis, early isolation.
“Early protection” actually means self-protection, the most important thing is self-protection, including distance, wearing a mask, etc. Early detection, that is, if you feel uncomfortable, see a doctor; early diagnosis and early isolation are the most important in China and other countries. s difference “We have community prevention and joint control. This is the most critical thing. We urge each other to remind ourselves to help. We know that this disease is mainly through droplets and contact infections. As long as we avoid this, we can avoid most of infections. ” Zhong Nanshan said.
It is important for international students to go shopping
Occasionally, international students must go out to buy the necessary living materials, what should they pay attention to in this process?
Zhong Nanshan said it is safe at home or in the bedroom, but be sure to wear a mask when going out. “Viruses rarely circulate freely in the air, they stick to something and most of them stick to drops and spread to others. General masks can prevent drops, so we can prevent most viruses, wearing a mask works enough. “
Zhong Nanshan explained that the drops would not run too far, probably no more than 2 meters after coughing. So, until now, airborne viruses cannot exist alone and freely, they are always bound to some substances. He said: “Now most countries have realized that wearing a mask is afraid that others will pass it on. This is a big change. Many European countries have to unlock it, but they must wear masks when they go out.”
Disapproval of “group immunization” for a vaccine
According to Zhong Nanshan, there are reports in Europe that 20% of people have antibodies, with the highest reported being 25%. This number is far from the so-called “group immunization”. % Of people have this possibility after infection, but it is far from being reached now.
Zhong Nanshan said he did not approve of “group immunization” and said he would sacrifice many people. “Even if it is 1%, it is more than a dozen, twenty times, or even a hundred times higher than the flu. If you have 2%, 3%, that is even more terrible. You have to sacrifice many people to get immunity. group. I don’t think this method is feasible. We have many ways, we can prevent, we can protect and we will fight for time to make vaccines, “said Zhong Nanshan.
Epidemic prevention abroad must not “go to the field”
The epidemic is an outbreak worldwide, how should foreign students improve their immunity abroad to prevent infection? “My personal opinion is that we don’t want people to be ‘clouds and clouds’, and we don’t want to go to the fields and follow customs. We have our own practices and let’s not be ashamed,” said Zhong Nanshan.
He said that at first, many people in foreign countries had a strange eye on the Chinese who wore masks, thinking that people who wore the masks must be sick, and now everyone has changed, even those who were very opposed to wearing masks before.
Distinguishing between influenza and new coronary pneumonia depends on detection
Flu and new coronary pneumonia have some similar symptoms, how to distinguish between flu and new coronary pneumonia?
China’s National CDC reports that the prevalence of influenza has decreased by 90% in more than three months. “This is because everyone pays to keep a distance and wear a mask. The symptoms of influenza are very similar to those of the new coronary pneumonia virus. First, it is a full body. At first, fever It can represent more than 50%, but not everyone has a fever, the flu also has this situation. ” At first, the whole body is uncomfortable, stuffy nose, mild cough, especially fatigue, making it difficult to identify just because of the symptoms, if not tested it is difficult to identify. “
“In China, if you go to the hospital with a fever, you will have a nucleic acid virus screening test. In the United States, nasal swabs and pharyngeal swabs are used for screening,” said Zhong Nanshan. Additionally, Zhong Nanshan suggested that some cold medications, such as ibuprofen, can be used that are not harmful to the new coronavirus. “Right now, we can only make a differential diagnosis through testing,” said Zhong Nanshan.
There is no evidence that the new coronary pneumonia virus is spread through mosquitoes.
In live transmission, Zhong Nanshan said the virus’s survival rate and activity rate at high temperatures are poor, but there is no evidence that the new coronavirus can be transmitted by mosquitoes.
In general terms, the survival rate and the activity rate of the virus at high temperatures are relatively poor, so with the arrival of summer, the activity of the virus will decrease and the epidemic situation will also decrease in general. Although ultraviolet light is not as strong as disinfection with ultraviolet light, the high temperature is detrimental to the activity and spread of viruses.
“We know that mosquitoes can transmit many viruses. The most prominent examples are malaria and dengue, which are very common in Africa. But there is no evidence that the new coronary pneumonia virus is infected by mosquitoes.”
People with asymptomatic infections “would rather believe it than have it”
Zhong Nanshan said that the majority of imported patients in China are now asymptomatic. In general, all asymptomatic infected people who are detected should “prefer to believe in its existence or not” and carry out appropriate isolation. Because the asymptomatic infected person is contagious within the first five days of developing symptoms.
“It is understood that the first five days and five days after new patients with coronary pneumonia develop symptoms are when the virus is most likely to infect people. Five days after illness, unless patients are very heavy, the general viral infectivity decreases. ” Zhong Nanshan It is believed that all nucleic acid positives in China now go to designated hospitals for isolation, and then come out after a negative test and then come out. This situation requires repeated tests to reach a good conclusion.
New sequelae of coronary pneumonia will not be obvious
During the live broadcast, an international student asked: If it comes out and gets infected, does it have any sequel? In this regard, Zhong Nanshan said that the new coronary pneumonia will not cause too much damage to the lungs and that the sequel will not be obvious. “Young people generally have stronger antibodies. If they don’t have many diseases (such as heart disease, kidney disease, liver disease, etc.), they generally recover faster. Drinking more water and taking medicine will recover on its own.”
Zhong Nanshan added that the patient is recovering well, including the lungs. The new coronary pneumonia is better than SARS, unless particularly critical patients affect the hematopoietic system, affecting the liver, kidneys and lungs. After recovery from the new case of coronary pneumonia, pulmonary fibrosis is not too heavy and appears to be reversible. “Lung function tests have been performed on more than 100 patients, and they have not returned to normal levels, but the damage should not be too great and it will recover slowly, and the sequelae are not great” (Reporters Zhang Shuhong, Deng Xiaoli )
