·"Actively looking for positive" violates the principle of controlling the source of infection, cutting off the transmission route and protecting susceptible groups, and may cause some unnecessary spread or prolongation of the epidemic. In addition, "early sun" does not necessarily "better early", because after the Omickron strain is infected, there is still a risk of reinfection, and it is not lifelong immunity after one infection.
·When the infection peak occurs, close contact tracking cannot solve the effect of flattening the curve, and it is impossible to truly achieve accurate close contact tracking. To lower the infection peak, it still needs to rely on non-drug intervention measures . It's already very difficult now.
At present, China's new crown epidemic prevention and control is facing "new situation and new tasks".
The relaxation of epidemic prevention policies and the possible peak of the epidemic have aroused public attention and heated discussions. Social media is full of remarks such as "Before Yang is the Respect" and "Before Yang is Good Early", and antipyretics and antigen kits are out of stock. Some people even cause acute liver damage due to taking multiple drugs at the same time. According to China Youth Daily, on the evening of December 9, the fever clinic of Beijing Chaoyang Hospital affiliated to Capital Medical University was lined up in a long queue. Some people waited for more than 6 hours. Medical experts called for "not to come to the hospital unless necessary", and the Beijing Emergency Center called for "asymptomatic patients and mild patients not to call the 120 hotline."
In recent days, many experts have spoken out on issues related to the new crown epidemic. On December 8, Zhang Wenhong, the director of the Department of Infection of Huashan Hospital Affiliated to Fudan University, released the "Huashan Infection Home Guidelines for Infection of the New Coronavirus" on the official account of "Huashan Infection", proposing that "99.5% of people may not need to go to the hospital. Family doctors of in Community Health Service Center and doctors in the hospital fever clinic can be solved by telephone, Internet or in-person consultation. However, our medical system must ensure that 0.5% of patients should be admitted to the hospital."
As the number of infections surges, it has become an expert consensus. According to First Financial , some experts believe that prevention and control measures should still be strengthened in key places such as nursing homes and schools. In the future, the tracking of "close contacts" will be unsustainable, and the public's self-management awareness will become particularly important.
On December 9, Zhong Nanshan, an academician of the Chinese Academy of Engineering, said in an interview with reporters in Guangzhou that the current focus of prevention should shift from preventing infection to preventing severe illness, and strengthening COVID-19 vaccination is the next key. According to the team model, it is expected that the first wave of infection peak in Guangzhou may arrive from mid-to-late January to mid-February next year, and enter a stable stage in mid-to-late March. It is optimistic that it will return to its pre-epidemic living conditions in the first half of next year.
"Beginning sun and good early"? What are the risks of multiple infections? How to prevent infection under the situation of relaxation of epidemic prevention and control? On December 10, Pengpai Technology connected with eight front-line clinical doctors and experts in China to interpret the issues related to the new crown that are generally concerned about by the people. They are: Deputy Chief Physician of the Department of Respiratory and Critical Care Medicine of Shanghai Pulmonary Hospital Affiliated to Tongji University Zhang Yuan , Researcher of Tsinghua University School of Medicine, Molecular Virology PhD Ding Qiang , Chief Physician of the Department of Respiratory Medicine of Zhongshan Hospital Affiliated to Fudan University Song Yuanlin , Shenzhen Third People's Hospital Infectious Doctor Lin Yuanlong , Chief physician of the Department of Respiratory and Critical Care Medicine of Shanghai Pulmonary Hospital Affiliated to Tongji University Liang Shuo , Director of the Epidemiology Teaching and Research Department of Fudan University School of Public Health Wang Weibing , Dean of Shenzhen Third People's Hospital Lu Hongzhou , Department of Liver Surgery of Zhongshan Hospital Affiliated to Fudan University Chief physician of the Institute of Liver Cancer of Fudan University Yang Xinrong .
More than 0 experts said that most of Omickron infections are asymptomatic or mild, but there is also a risk of multiple infections. "Premature sun" does not necessarily mean "better early", so you must be wary of the side effects caused by the combined use of drugs.
Q1: Early sun really gets better?
Zhang Yuan (Deputy Chief Physician of the Department of Respiratory and Critical Care Medicine, Shanghai Pulmonary Hospital Affiliated to Tongji University): I personally do not agree with the view that "beginning and early sunlight are good", and even "take the initiative to look for Yang". The principle of management of infectious diseases is to control the source of infection, cut off the transmission route and protect susceptible people. This is a very classic summary of experience."Actively looking for positive" violates this principle and may cause some unnecessary spread or prolongation of the epidemic. In addition, "early sun" does not necessarily mean "better early". After the Omickron strain is infected, there is still a risk of reinfection, and it is not lifelong immunity after one infection.
Ding Qiang (researcher at the School of Medicine of Tsinghua University and Ph.D. in Molecular Virology): The so-called "early sun and good luck early" is a mentality, and there is no scientific reason. There is no need to "take the initiative to look for the positive", but according to the current situation, many people may be infected once, just work and live normally.
Song Yuanlin (Chief Physician of the Department of Respiratory Medicine of Zhongshan Hospital Affiliated to Fudan University): Currently, the new coronavirus is low in toxicity, and most people have mild symptoms after infection, especially young people. After infection, a similar immunization is performed, which will produce protective antibodies. Generally, high antibody titers remain within 6 months and will not be infected with Omickron again. But there is no need to deliberately infect and challenge. Because the infection will be transmitted to other people in a short period of time, especially when accidentally encountering special groups, family members, etc., some special groups still need to take certain protection at present.
Lin Yuanlong (infectious doctor in Shenzhen Third People's Hospital): In early December, researchers from the University of Hong Kong , , , , , and some articles in the journal ", Nature " mentioned ", long COVID, also known as "long-term symptoms of new coronavirus", such as loss of taste and smell, brain fog, decreased attention and memory, insomnia, emotional instability, etc., and some patients may experience impotence. Although these symptoms do not threaten life, they still have some functional effects. Viruses are used to detoxify in the nasal cavity or upper respiratory tract, but viruses are also present in the blood. The brain has a blood-brain barrier, and viruses can enter the brain, but immune cells cannot enter. Therefore, the impact of the new coronavirus on the brain is conclusive, and it will cause apoptosis of brain cells. It’s just that the “new crown” is a small probability event. So we definitely cannot say that "early yang is better sooner". It is definitely that the later the yang, the better, and it is best if there is no yang.
Liang Shuo (Chief Physician of the Department of Respiratory and Critical Care Medicine, Shanghai Pulmonary Hospital Affiliated to Tongji University): Every doctor hopes that patients can avoid infection, and that if they can avoid illness, they should not get sick. First, after being infected with the virus, some people have symptoms, such as fever, cough, headache, or other discomfort, which affect their work and life; second, after being infected with the new coronavirus, they will not gain lifelong immunity. Everyone is the first person responsible for their own health. For themselves and for their family, don’t “take the initiative to look for Yang”.
Q2: Will multiple infections damage the human body?
Wang Weibing (Director of the Epidemiology Teaching and Research Department of the School of Public Health, Fudan University): has a certain immunity to the same new coronavirus for a period of time after the previous infection of , so don’t worry too much about secondary infection with . But as time goes by, resistance will gradually decline and may be infected again. In addition, due to the enhanced immune evasion ability of some new variants, other variants may be infected again after half a year.
Song Yuanlin: Generally, people will not be infected within six months after infection, but the antibody titers produced after infection are related to their immunization status. Immunely deficient people may produce protective antibodies in their bodies with titers , which will be low, the time will be short, and the protective power will be weakened to a certain extent. When facing low-toxic virus strains, don’t worry about multiple infections. The previous infection is equivalent to getting vaccinated with vaccine , which will have a certain protective effect.
Ding Qiang: The statement that "usually, you will not be infected within half a year after infection" actually mainly refers to the infection of the same mutant strain. There are many mutant strains now. If the infection is not the same virus, cross-protection is not feasible. So it still depends on the specific situation. The current epidemic strain in China is mainly Omickron, so I think it should not be infected again within half a year after infection.
Lin Yuanlong: multiple infections cause greater damage to the body. There is such a situation, but this is also a probability problem.The possibility of "new coronavirus" symptoms appearing after one infection is relatively small, and the possibility of "new coronavirus" appears after two or three infections increases. But basically, if the same virus does not mutate, the possibility of reinfection is relatively small.
Q3: How to determine whether it is a mild or severe disease after infection? How to distinguish between COVID-19 and influenza? When do you need to go to the hospital? Will there be a situation where seasonal flu and the new crown epidemic occur?
Lu Hongzhou (Director of Shenzhen Third People's Hospital): Most patients with new coronavirus infection have mild symptoms. According to data from Taiwan's "Central Epidemic Command Center", from January 1 to December 9, 2022, there were 8389,013 local cases, of which 99.55% were asymptomatic infections of mild and , , 0.26% were moderate and 0.19% were severely infected.
The new coronavirus infection is currently more likely to manifest as upper respiratory tract symptoms such as sore throat, headache or muscle pain. The incubation period is contagious. The progress of COVID-19 infection among special groups such as underlying diseases is severe and has a high risk of death. Whether at home or abroad, patients with comorbidities and immunosuppressive status have significantly higher risk of mortality (ICU treatment and invasive mechanical ventilation) and are significantly higher than those of the general population. Among them, malignant tumors, diabetes , hypertension , chronic obstructive pulmonary disease (COPD), chronic liver disease, diabetes, neurodegenerative lesions, chronic lung disease, immunosuppressed population, and chronic kidney disease are all independent risk factors for the progression of severe illness or death in patients with the new coronavirus. Even if the symptoms are mild, the detoxification time after infection is long, which is not conducive to rapid recovery of social life.
Zhang Yuan: Common symptoms of non-severe high-risk people include fever, sore throat, cough, nasal congestion, etc. and similar symptoms to "cold". If you experience uncommon symptoms such as chest pain, , obvious dyspnea, and confusion, you need to seek medical treatment in time.
Ding Qiang: The symptoms of people around me after infection are basically like colds, and most of the symptoms of fever. People with severe illness, such as those who continue to have high fever, should go to the hospital in time. Antipyretics should be the most important thing. Many other drugs are auxiliary means, or even psychological comfort, which are not decisive.
Influenza is like the new crown, and it is very contagious. As far as I know, the situation of influenza in China this year is not very serious. There is a flu vaccine for treating influenza, and you can get vaccinated in time. Even if you really have influenza, there is no need to distinguish whether it is influenza or the new crown, and you can be quarantined at home.
Song Yuanlin: Omickron will generally experience fever, throat pain, dry mouth, , etc. after infection. The above respiratory symptoms are mainly the above, which will rarely cause lower respiratory symptoms. In addition to the new crown, influenza should also be considered. Winter and spring are also the peak season for influenza. In recent years, with masks worn, most people have not been exposed to influenza, so they are also susceptible to influenza. If you have fever, it may not be the new crown, and it may also be the flu. It is recommended that special groups should not only prevent Omickron in the near future, but also pay attention to preventing influenza. Influenza treatment includes effective anti-influenza virus drugs, and influenza vaccination can also be considered.
Infection with the flu will cause symptoms such as muscle soreness, fever, cough, headache, etc., but the flu does not have a sense of smell and taste. Sometimes it is not easy to distinguish between the two according to symptoms, and the possibility of simultaneous existence is not ruled out. PCR nucleic acid testing of nasopharyngeal swab or oral swab is required. The main difference between the severity of the new coronavirus infection is whether there is hypoxia, which is manifested as shortness of breath (more than 25 times), and the pulse oxygen meter indicates that the blood oxygen saturation is less than 94%. If you have severe cough, dyspnea, dyspnea after activity or your blood oxygen saturation decreases, you can go to the hospital for treatment.
Lin Yuanlong: The new crown is currently in the most contagious stage. It is generally a little heavier than the common cold and a little lighter than the flu. It may be manifested as severe sore throat, dry cough, headache, fever, muscle aches, fatigue, etc. Age and high-risk factors greatly affect the severity of symptoms. Most young people will have high fevers. Asymptomatic people generally have underlying diseases such as diabetes, or are weak and thin. Because they have poor immunity, they turn yin more slowly, and people with high fever may turn yin faster.Therefore, asymptomatic and mild symptoms do not represent the severity of the COVID-19 infection. What the COVID-19 infection ultimately fears is the impact of the "new crown".
If you are an elderly person, or someone who has had underlying diseases before, bacterial pneumonia may be triggered after infection, which will be more serious, but the probability is also very small. Currently, there are very rare patients who cause pneumonia by Omickron, and may not be seen in thousands of patients. The country requires patients with severe symptoms to go to designated hospitals. In our hospital, patients with high-risk factors are in good condition, but the transition from negative will be slower. Generally speaking, it takes about 10 days to turn Yin. The nucleic acid may be faster after the test. According to the time when the symptoms disappear, it should be able to recover within 4 days, and it can recover in an average of 1-2 days. But the cough may last for 1-2 weeks, or even 1-2 months.
Since the winter this year, the flu situation in China has not been serious, and the more serious flu is from May to August this year. The symptoms of COVID-19 and flu are similar, both of which are flu-like symptoms . The flu will not have symptoms of "new coronavirus".
Wang Weibing: Influenza really needs to be careful. When social distance relaxes, the flu will also spread. Not only influenza, but some viral pneumonia (such as RSV) may also increase. China needs to increase pathogen testing in fever clinics and prevent it in a timely manner. People can consider getting vaccinated.
Q4: How to take medicine? When is the most effective time to take medicine?
Song Yuanlin: Most people with new coronavirus infection are asymptomatic and do not need treatment. A small number of people experience fever, throat pain, etc. Generally, symptomatic treatment will be relieved soon. For example, taking some cold and antipyretic drugs, or traditional Chinese medicines to clear and detoxify, drink more water during the fever and after the heat drops out of sweating to avoid excessive blood volume. Most families do not need to prepare these drugs. If you want to prepare, it is also a common medicine for preparing for colds.
If is detected as positive for , there is no symptoms and no treatment is required. If there is fever or throat pain, you can use antipyretic and analgesic or clear heat and detoxification drugs. Patients with relatively severe cases need to go to the hospital for antiviral treatment and supportive treatment. Commonly used cold medicines are often compound preparations, including blood vessel shrinking drugs (treating nasal congestion such as pseudoephedrine ), anti-allergic drugs (cough and nasal congestion, such as chlorine), antipyretic drugs (acetaminophen), and antipyretic drugs ( dextromethorphan , etc.). Among them, the antipyretic drug acetaminophen is relatively safe, and in some cases excessive amounts may cause liver dysfunction. It is not recommended to take it at the same time as antidepressants, or to reuse other antipyretic and analgesic drugs.
Wang Weibing: can stock up on some antipyretic drugs, but it is not necessary to stock up on other drugs. In addition, it is necessary to avoid the phenomenon of superimposed use of drugs with similar functions. For example, some cold medicines have antipyretic functions. At this time, there is no need to take cold medicines and antipyretics at the same time.
Zhang Yuan: has symptoms such as fever and sore throat, and needs medication to relieve it. You can use the right medicine. Blind combinations of multiple drugs are not recommended. If the medication ingredients are repeated, excessive, or the indications, contraindications and other improper medications are ignored, there is a risk of liver damage.
Lin Yuanlong: Take medicine when there are symptoms. Do not take too much medicine, as it may lead to liver failure. Currently, two special drugs for the new crown are on the market, including , Azfuding from Henan Zhen Biotechnology Co., Ltd. and Paxlovid from Pfizer in the United States. Because it is the prescription drug , it is not available on the market now, and can only be purchased in designated hospitals. These special drugs have the effects of reducing viral load and accelerating the conversion of negative effects. If you have the conditions to purchase, it is recommended that the infected person take it. I don’t recommend taking Chinese medicine casually. Studies have shown that Chinese medicine can be treated symptomatically, but its effect of lowering the virus is not outstanding.
From the perspective of symptoms, if you don’t take medicine, you can get better in 1-2 days. If the symptoms are serious, it may not be relieved 4 days after taking medicine. There is currently no special medicine to relieve symptoms. But as long as it can be helpful in quickly reducing the virus, it can reduce the risk of infection and reduce the chance of the virus lurking into the brain.
need to pay attention to the side effects of antipyretics, some of which will damage the stomach, leukocytes and immunity.Generally, no antipyretic drugs are needed for fever below 38.5℃, and adults do not need to use antipyretic drugs until the fever reaches 39℃, unless the headache is very severe.
Yang Xinrong (Chief Physician of the Department of Liver Surgery at Zhongshan Hospital Affiliated to Fudan University and the Institute of Liver Cancer of Fudan University): The combined use of multiple drugs may cause liver damage, especially cold drugs, such as anti-inflammatory and painful , which will lead to acute liver failure. Recently, a patient had liver transplant at Zhongshan Hospital due to taking cold medicine. Cold medicines are generally used in one or two types, and are mainly used for symptomatic treatment, such as antipyretics, cough medicines, antibiotics, , etc. Fever antipyretics should be paid special attention to, and they should not be used for a long time when they are used in a short period of time. Generally, try not to take Western medicine antipyretics and Chinese medicine cold medicines together. Sometimes Chinese medicine preparations also contain similar ingredients to Western medicine, which can easily lead to excessive amounts. sclera yellow , yellow urine, fatigue, poor appetite, and anorexia, especially greasy, and need to pay attention to it. You should go to the hospital to check liver function.
Q5: Do nucleic acid confirmation still need to be confirmed when positive antigen? Do you still need to take the initiative to do nucleic acid?
Lin Yuanlong: is usually done with antigen . Drivers, vegetable market owners, doctors and other high-risk groups need to be nucleic acid. 99.9% of antigen detection is accurate, and antigen specificity is particularly high, but positive can only be detected within 3 to 5 days after infection, that is, when the infectiousness is the most common. Antigen negative does not mean that there is no infection, but antigen positive must be the infected person. Therefore, there is no need to confirm the positive antigen. Nucleic acids are abnormally sensitive. If the antigen is negative but it is actually infected, the nucleic acid can also be detected.
Song Yuanlin: The results of antigen detection are generally acceptable, indicating that it is highly contagious, which is of course related to the sampling location and infection time. If the self-test antigen is positive, it is recommended to stay at home. Nucleic acid is not necessary. If you have any symptoms, you should self-manage at home. If you have obvious symptoms, you can go to the hospital for treatment. People in special occasions still need to undergo nucleic acid tests, but the overall frequency of nucleic acid tests is decreasing. At present, the hospital system still has the requirements for nucleic acid testing for , so if you want to go to the hospital, it is still necessary to take personal protection during this period to avoid infection.
Wang Weibing: can take the initiative to do nucleic acid when needed, but you can not do it if you don’t need it (such as at home). When respiratory symptoms occur, antigen self-examination can be used. The sensitivity of the antigen is not as sensitive as that of nucleic acids, and it also has a certain false positive rate of . If the antigen shows positive, nucleic acid confirmation can be performed if conditions permit. If conditions permit, re-test with antigen, but it is best to change the brand of antigen reagent.
Liang Shuo: High-risk positions and high-risk areas perform nucleic acid testing in accordance with relevant regulations, and other personnel are willing to be tested. If you are preparing to go to a special place, such as a medical institution, especially if you need to perform some risky operations or examinations, such as , lung function, or endoscopy when you go to the respiratory department, it is recommended to prepare nucleic acid in advance. To avoid the risk of infection, the most important thing is to protect yourself. Wearing a mask is very important.
Ding Qiang: There is no need to take the initiative to do nucleic acid at now. Doing nucleic acid will increase the risk of infection. If necessary, avoid peak periods and take personal protection. Compared with nucleic acid testing, antigen testing is not very accurate and there will be more false negatives. False negative means that you are actually infected, but you cannot detect it. If the antigen is positive, there is no need to do nucleic acid, because nucleic acid must be positive. Antigens and nucleic acids detect different components of viruses. Testing antigens is to measure virus proteins, and nucleic acids is to measure virus gene sequences. Overall, nucleic acid detection is more sensitive, so nucleic acid positive is easily detected, and antigen is not easily detected, so false negatives in antigen testing will be more serious.
Q6: Do people who have received the third shot or have been infected with the new crown still need to get vaccinated?
Song Yuanlin: People who have received the third shot at the moment generally do not need to get vaccinated again if they are within six months, and there is no need to get vaccinated again if they have been infected recently.
Wang Weibing: For people who have received the third inactivated vaccine, if it has been more than six months, it is recommended to strengthen it again. You can pay attention to the national notice on the fourth vaccination.
Ding Qiang: depends on personal situation. Most people get the first three shots of inactivated vaccine . The inactivated vaccine has no protection against mucosa immunized . The recently launched nasal spray vaccine can cause good mucosal immune protection. If you have the conditions, you can get it. As for whether people who have been infected before need to get vaccinated, we need to analyze the specific questions of in detail, and it depends on which mutant strain was infected before. In Beijing, the main popular one is Omickron BF.7. If you were infected with other mutant strains in the past, the cross-protection was relatively weak and you might have to get vaccinated. If the person who was infected before was Omickron, he might not have to be beaten again.
Lin Yuanlong: The authoritative statement is that you can fight after being infected with the new crown for half a year. Infecting with the new coronavirus is like getting hundreds of shots in one go.
Q7: After the release, how should ordinary citizens protect themselves?
Song Yuanlin: In the environment of gradually relaxation, with the development of social activities, it is very difficult to completely avoid infection. Most people can adjust the pace of life accordingly as policies change. The bottom line of this practice is that the symptoms after infection are mild and the mortality rate is very low.
Specifically, you need to consider your own physical fitness and the physical fitness of your family and colleagues in the unit. Do not deliberately pass it on to others after infection. Currently, it is open in an orderly manner. Special occasions such as the hospital's surveillance rooms and patients with immunodeficiency/suppression all require certain protection. Therefore, people who come into contact with these groups need to take their own protection in the short term to avoid transmission of self-infection to people with immunosuppression due to their own infection. N95 masks and hand hygiene can effectively reduce the risk of infection to a certain extent.
Zhang Yuan: On the one hand, strengthen self-management, do a good job in the "three-piece set" and "five-first" (the "three-piece set" of epidemic prevention refers to wearing masks, maintaining social distance, and paying attention to personal hygiene; the "five-first" of protection refers to wearing masks, keeping social distance, covering coughs and sneezes, washing hands frequently, and opening windows as much as possible), and reducing the risk of exposure. On the other hand, regular work and rest, balance nutrition, pay attention to keeping warm, avoid anxiety and other weakening resistance.
Liang Shuo: 1. Take careful protection and avoid repeated infections as much as possible. As winter comes, not only the new crown, but also many respiratory pathogens need to be paid attention to, such as influenza virus, respiratory syncytial virus and other viruses, as well as bacteria such as Streptococcus pneumoniae and Haemophilus influenzae . People with low immunity should also pay attention to avoid fungal infections. 2. Improve your resistance and are nutritious. The structure of protein carbohydrates is reasonable. It is best not to use dieting and other weight loss methods. 3. Pay attention to rest and ensure sufficient sleep time, especially try not to stay up late. 4. Exercise in moderation and avoid excessive exercise.
Lin Yuanlong: Wear a mask, especially in crowded places. Wearing an N95 mask in winter is the best. Taxi drivers, bus drivers, shopping mall employees, doctors and other high-risk groups should wear N95 masks. Try to avoid gatherings. Wash your hands frequently. Drink more water, eat more high-quality protein such as fish, beef, and mutton, and vegetables such as cabbage and radish, for a balanced dietary nutrition.
Lu Hongzhou: fragile groups are vaccinated as soon as possible. It is best to get a heterologous vaccine booster. The clinical characteristics of the new coronavirus infection are that they are mild in the first week or even have no obvious symptoms. Once infected, do not miss the best treatment period. The antiviral treatment effect is the best within 5 days before onset, which can prevent the patient from developing severe illness in the second week. As we grow older, the thymus atrophy, and the antibodies produced by thymus T lymphocytes in 60-year-olds are only 15% of those of young people. Let’s not talk about other older ages. Vaccines are not as important to the elderly as young people. The older the age, the worse the bone marrow regeneration ability, and the immunity of B lymphocytes and will naturally decrease.
Q8: Do the elderly need to "actively isolate"?
Lin Yuanlong: The elderly still need outdoor activities and cannot be inactive just because they are afraid of the new crown.For example, wear a mask and take a walk outdoors. When going to the vegetable market, you must wear a mask and change the mask frequently. If you are going to a confined space with dense crowds such as shopping malls and supermarkets, it is best to wear N95. After you have been there, you should throw away the mask you have worn. It is not necessary for relatives and friends to visit each other. You can make an antigen before visiting. It is also OK to make nucleic acid, but now the cost of making nucleic acid is too high, such as the waiting time is very long. Therefore, antigens are becoming more and more important.
Wang Weibing: After the new crown test is positive, it is recommended to observe at home first. If there are no symptoms, you do not need to take any medicine. If you have symptoms such as fever, you can use some medicines with the help of family doctors or medical staff in the community health service center. You can also use the Internet hospital to take medicine after asking for advice from doctors.
For the elderly or people with deficits in immune capacity, they can maintain social distance from the outside world at the peak of the epidemic, safely survive the peak of the epidemic, and avoid being infected when medical resources may be tight, thereby delaying treatment.
Song Yuanlin: There is currently a hotline for consultation, or if there is a doctor around you, you can consult. How to deal with the flu and colds in the past, and now it is also how to deal with it. The drugs needed include Internet clinics, online purchase of medicines, or volunteers, etc. However, special groups need to be paid attention to, people over 60 years old have underlying diseases, including obesity, hypertension, COPD, , asthma, , lumbar expansion, coronary heart disease, diabetic, tumor, kidneys require hemodialysis, , lymphoma, leukemia , myelodysplasia and other diseases, as well as patients who take corticosteroids for a long time, and patients with organ transplants use immunosuppressants for a long time, etc. These groups need key protection at present. At this stage, it is best for the elderly and special groups to avoid going to places with a large population and try to avoid infection.
Q9: How to flatten the infection curve?
Ding Qiang: It is difficult to actively track close contacts at at present. It is mainly due to the public's consciousness and some administrative power. It is already very difficult now.
Wang Weibing: When the infection peak occurs, close contact tracking cannot solve the effect of flattening the curve, and it is impossible to truly achieve accurate close contact tracking. To lower the infection peak, non-drug intervention measures still need to be relied on. For example, the maintenance of social distance can truly lower this "curve" and to a certain extent lower this peak. However, while lowering the peak, it may prolong the entire epidemic process.
countries have a certain estimate of the proportion of positives every day, and this data is very important for judging the epidemic. In addition, the number of beds in designated hospitals and the number of ICU beds can also reflect to a certain extent the proportion and number of severe and critical illnesses, as well as the tightness of medical resources, which will have a relatively large impact on future response. There is also data on self-test antigens, such as "epidemic test". The disclosure of these epidemic prevention data is particularly important.
Lu Hongzhou: Ensure the supply of medical resources. In the absence of medication, designated hospitals need to be relied on for antiviral treatment. Develop effective and long-acting nasal spray vaccine as soon as possible to stimulate cellular immunity and respiratory mucosa immunity to prevent viral infection.
