This is my second Q&A today about who is more infectious and susceptible to the new coronavirus, smokers or non-smokers. In the last answer many people said I couldn't come up with data to prove which one is more susceptible to infection, and all of the content is my own opinion.

So now the data is here, let's take a look at the data that Academician Nanshan Zhong published in a recent paper to see. One of the data in Academician Nanshan Zhong's paper talks about the prevalence of smoking in the population.

Among the 1099 infected patients, 927 patients have never smoked, accounting for 85.4%, 21 patients have ever smoked, accounting for 1.9%, and 137 patients are still smoking, accounting for 12.6%. We then check Baidu, according to Baidu's data show that China's current smokers amounted to 301 million, the smoking rate of people over the age of 15 is 28.1%, of which 52.9% of men and 2.4% of women. From the above data it seems as if smokers are less prone to the new coronavirus pneumonia.

Seeing this statistic many smokers have been justified and said, "See, smoking is good for preventing viral infections, right, and you still say that smoking is bad for your health?

Don't be too happy yet, I will slowly analyze for you whether this data is representative or not: First of all, this data is only about 1,000 cases, the data is relatively small, and the chance is also larger. We need to wait for big data to minimize the chance. If you synthesize the data of tens of thousands of cases to analyze, then it will have a certain persuasive power. Secondly, in this 1099 data, there are 459 females and 540 male patients. According to the smoking rate of males and females, it is 52.9% for males and 2.4% for females, and the number of female smokers is negligible. So the true figure would be 137/540 with a probability of 25.3% which means that the proportions are actually the same.

Once again, it is clear from previously published Lancet data that long-term smokers with novel coronavirus pneumonia have a higher probability of progressing to severe or even critical illness. And from the analysis of the data in this paper by Academician Nanshan Zhong, it was found that 25.2% of these patients had a combination of at least one underlying disease (e.g., hypertension, chronic obstructive pulmonary disease, etc.).

Smoking is a risk factor for hypertension, chronic obstructive pulmonary disease (COPD), and cancer (including lung and bladder cancer). Finally, coupled with the fact that the latest version of the Pneumonia Diagnostic and Treatment Program for Novel Coronaviruses is characterized by a general susceptibility to novel coronaviruses, there is no such thing as smokers not being susceptible or non-smokers being susceptible.

Finally concluded: smoking is not beneficial, smoking a hundred harm and no benefit, we should not be lucky, that smoking helps to prevent viral infections, if that's the case, but also the study of drugs for what, but also the study of vaccines for what, a cigarette can be solved things, and why until now is still looking for a hard to find a special drug it. All in all, it is still the same saying that wearing a mask when you should wear one and washing your hands when you should wash them are the scientific ways to prevent viral infections.

Purely hand-typed, it is not easy, if you feel that the writing can also be rewarded a praise, point a concern, if you have any questions can be left below ......

Who is most likely to be infected by an infectious virus, smokers or non-smokers?

There is no difference in this. The Pneumonia Treatment Program for Neocoronavirus Infections (Trial Fifth Edition) states that neocoronaviruses are universally susceptible to the population. In other words, whether you smoke or not, how old you are, whether you are a man or a woman can be infected by the new coronavirus. Relevant studies have shown that the new coronavirus infects humans by binding to the ACE2 protein, which is commonly found in human organs and tissues (e.g., the mucous membranes of the mouth and nose, nasopharynx, lung tissues, and the digestive tract), so we humans can be infected if we come into contact with the virus up to a certain concentration.

However, it is important to note that smokers who are infected with the new virus are more likely to develop serious illnesses

According to the CDC, compared with the general population, patients with chronic diseases have a relatively faster progression of disease, higher severity, and greater risk of death after infection with novel coronaviruses.On the one hand, this part of the population has a relatively low resistance itself, and on the other hand, these people have a chronic low-grade inflammatory response themselves.而Smoking not only damages lung tissue, but is also a high-risk factor for many chronic diseases and cardiovascular diseases, such as chronic obstructive pulmonary disease, hypertension, diabetes, coronary heart disease, cerebral infarction and so on. Therefore, we would like to call on you not to smoke, especially those who have these chronic diseases and are older.

Welcome to like, forward, leave a message, I am physician Yang Hao, focusing on common diseases, multiple diseases diagnosis and treatment, chronic disease management, health science. If you want to know more about medical knowledge, welcome to pay attention to this headline!

Who is most likely to be infected with the virus, key smokers or non-smokers?

Smoking is harmful to health, this is not true at all, the biggest health hazard of smoking is to cause damage to people's respiratory system, mainly harmful substances in cigarettes, such as tar, nicotine, benzopyrene, etc. can harm the airway, resulting in a decrease in the self-purifying ability of the respiratory tract, harmful substances can stimulate the airway to produce mucus to increase and stimulate the parasympathetic nervous system leading to bronchial smooth muscle contraction, the end result is to cause the respiratory tract breathing Resistance increases, tar and nicotine and other substances can cause an increase in oxygen free radicals, too many oxygen free radicals can lead to the respiratory system of elastic fiber damage caused by the decline in elasticity, the end result is to lead to people's resistance to disease and disease prevention ability to varying degrees of decline, but also can cause chronic bronchitis, chronic obstructive pulmonary disease, emphysema and pulmonary heart disease.In addition, nicotine and benzo(a)pyrene can cause lung cancer, which ultimately leads to reduced quality of life and shorter lifespan.

As you can see from the above, smoking does more harm than good. Of course, there have been many rumors about the ability of smoking to fight the new coronavirus, but the damage that smoking does to the respiratory system is such that this rumor is not disproved.

Smoking not only can not resist the new coronary virus, but also lead to people's respiratory system and other damage and decline in resistance to disease, because smoking leads to a decline in people's resistance, so smoking leads to the infection of the new coronary virus infections than non-smokers have a higher chance, and long-term smokers once infected with the new coronary virus, the risk of developing severe new coronary pneumonia and severe new coronary pneumonia will be increased to varying degrees.

Smoking is harmful to health, people who do not smoke, it is best not to smoke, if you already smoke and have become addicted to smoking, it is best to quit smoking, really can not quit smoking, but also to limit or reduce smoking as much as possible.

In effect the question is asking whether the nicotine chemicals contained in the lungs of smokers are positive or counterproductive in counteracting this epidemic?

Since no one has conducted any tests on this so far, no one can draw any convincing conclusions. If the authorities can do a breakdown of the number of confirmed patients and deaths to see what percentage of smokers and non-smokers are involved, it may shed some light on the problem.

As for some people's reasoning that smoking injures the lungs, resulting in weakened lung function, and weakness necessarily leads to low resistance, so the likelihood of contracting the virus is greater relative to that of non-smokers. This kind of reasoning is somewhat taken for granted.

There are two sides to everything. There is a bad side to the good and a good side to the bad. Arsenic is a poison, but it can also be used in medicine to cure diseases and save lives. Opium is poisonous but can be used as medicine to relieve pain and sickness. Bats are delicious, but they kill people.

Nicotine is also a poison that may damage a person's lungs, but who's to say if it also kills viruses?

Recently, I have often seen this statement, want to prevent viral infections, smoke some cigarettes; or those old smokers, will not be infected with the new type of virus, the lungs are full of tar, the virus will be poisoned to death, whether it is a self-mockery under the tension of the epidemic, or really think that there is a truth to it, but from the current statistical data of the study, there is no clear difference in the size of the chances of the smokers and non-smokers and the viral infections.

Recently, academician Zhong Nanshan as the corresponding author of the new coronavirus clinical statistics research many friends are very concerned, first of all, the longest incubation period of 24.0 days of the "record", many friends and more worried about, but in fact, has also been confirmed that, in the proportion of 1,099 cases, this 24.0 days of incubation period only a But in fact, it has been confirmed that among the 1099 cases, the incubation period of 24.0 days is only one case, and the median of the average incubation period is 3.0 days, therefore, for such a special case, we should not think too much and worry too much.

In this paper, the proportion of smokers among the 1,099 cases was also counted. In terms of the proportion of smokers among the patients who developed the disease, there were only 137 cases of smokers among the 1,099 patients, which accounted for about 12.6% of the total number of patients, so does such a figure mean that smokers are less susceptible to contracting the new type of coronavirus pneumonia? Don't worry, we'll analyze it for you slowly -

Among the 1099 cases, there are 459 females, and females are seldom smokers, which can be almost ignored. Among the remaining 640 males, there are 9 males under the age of 15 years, and among the 631 males over the age of 15 years, there are 21 males who used to have a history of smoking and now they no longer smoke, and there are 137 cases of those who are still smoking at the moment, which means that the proportion of the disease in males with a history of smoking is as high as 25%, which is actually not low, and there is also a certain degree of randomness in such a statistical sample size. The proportion of men with a history of smoking is as high as 25%, which is not low, and the sample size is not large and comprehensive enough, so it is believed that with the continuous improvement of epidemiological statistics, the proportion will be further increased.

Therefore, such a figure does not show that smokers are less likely to be infected with the new virus. When we look at it from another angle, out of the 1,099 cases, 927 were never smokers, and there were 134 cases of serious illness, which is 134/927 = 14.45%, while among people with a history of smoking, the ratio is 38/159 = 23.89%, and I believe we will know at a glance which one of them has a higher proportion of critical cases.

Previously, the WHO experts in the introduction of the new coronavirus infection related issues also talked about, the elderly, existing lung disease, or long-term smoking people, are prone to develop a critical condition of the risk of the situation, so it seems that smoking is not effective in reducing the chances of infection of the new coronavirus, but smokers once infected with the new coronavirus, the risk of developing critical symptoms of lungs, on the contrary, the chances of a higher rate of risk.

Smoking is harmful to health, we have been popularized for many years, smoking for the lungs, digestive tract, cardiovascular health and other aspects of health hazards, also said a lot, there are still a lot of friends (especially some of the friends who can not quit smoking), always like to find a variety of examples to prove that the "benefits" of smoking, to take a lone example of the situation to challenge the long-standing scientific concept that smoking is harmful to health, really ridiculous and sad. The situation, to challenge the long-standing scientific concept that smoking is hazardous to health, is really ridiculous and pathetic, smoking or non-smoking, are a person's personal choice, how to choose, mainly to see their own, there is really no need to have to prove that smoking can help the body's health, to help reduce the spread of viruses, you say is not it?

Epidemiologic surveys have shown that the population is generally susceptible to novel coronaviruses, and therefore both smokers and non-smokers may become infected with novel coronaviruses. However, there may be some differences in disease regression between smokers and non-smokers.

Smoking is harmful to the human body in many ways. As far as the respiratory system is concerned, smoking can weaken the immune function of the respiratory tract and reduce the resistance to viruses, and in the absence of effective medicines, the elimination of the new coronavirus relies mainly on the human body's own immune system, so theoretically speaking, smoking a lot over a long period of time is not conducive to the prevention of neocoronavirus pneumonia. Secondly, smoking can damage lung tissue, reduce lung function, and increase the incidence of respiratory diseases such as chronic obstructive pulmonary disease, asthma, and tuberculosis, etc. Among patients with new coronary pneumonia, those with respiratory diseases have a higher chance of progressing to the severe or critical type, and deaths also occur more often in patients with respiratory diseases, so long-term heavy smoking is not conducive to the regression of new coronary pneumonia, especially in patients who have already developed respiratory diseases; furthermore, smoking can cause the disease to become more serious, and the disease may be more serious. In addition, smoking increases the risk of chronic diseases such as diabetes mellitus, coronary heart disease, stroke, and peripheral atherosclerosis, and once infected with the novel coronavirus, the prognosis of patients with comorbid chronic diseases is worse than that of the general population, so that non-smokers may have a better prognosis in terms of disease regression.

Of course, it has only been a few months since the discovery of the new coronavirus last year, we know very little about the virus, and all aspects of the virus need to be studied in depth. Even though some of the data from the study can be used for reference, the sample size of the study is relatively small, and the individual differences also affect the risk of the disease and the regression of the disease, so the question of "who has a greater risk of infection, smokers or non-smokers? Therefore, the answer to the question "who is at greater risk of infection in smokers versus non-smokers" is not yet conclusive. Current epidemiologic surveys show that all populations are susceptible to novel coronaviruses, and perhaps the risk of infection is different for different individuals. Even if the risk of infection is small, once the infection occurs in one's own body, the rate of infection is 100%, and therefore all people, whether smokers or non-smokers, should take protective measures against neocoronavirus pneumonia. More importantly, the new coronavirus is mainly transmitted through the respiratory tract, and at this time of high incidence of the epidemic, smoking will undoubtedly increase the chances of coming into contact with the virus; if you are infected with the new coronavirus, smoking will also expose your family members to the virus, which is not conducive to the prevention of the new coronavirus pneumonia, so it is recommended to quit smoking, wear a good mask, and do a good job of protecting yourself from the virus in order to minimize the risk of infection.

In conclusion, long-term heavy smoking reduces the immune function of the respiratory tract, damages lung tissues and reduces lung function, which is not only detrimental to the prevention of neocoronavirus pneumonia but may also affect the regression of infected individuals, thus non-smokers are better able to resist neocoronavirus.

Here we go again, there are always some people who can't quit smoking, trying to find a little positive energy for cigarettes. Smoking is bad for your health" on the cigarette packet is the result of many bloody lessons.

Coronaviruses are like home invaders, and smokers do more damage.

There are two types of cells in the walls of human alveoli, type I and type II alveolar epithelium. This time, the new coronavirus looks like a crown with many small protrusions on its surface, which can adhere to type II alveolar epithelium through the echinocandin protein, burrowing into the cells to replicate like thieves prying at locks, and leading to cell death causing localized inflammation and a milled-glass shadow on CT:

In some cases, the body is resistant or sensitive to treatment, and the lesions can be quickly absorbed and get better, and in some cases even leave no trace.

A small number of severely ill patients will continue to progress, with more and larger lesions and even the formation of white lungs. This severe disease is most often seen in the elderly, especially those with high blood pressure, diabetes, and chronic obstructive pulmonary disease (COPD).

And this type II alveolar epithelium is equally susceptible to coronaviruses, regardless of whether one smokes or not.

Smoking lowers the immunity of the lungs.

The harm of tobacco is multi-systemic, in addition to causing and aggravating chronic bronchitis and emphysema, it is also related to atherosclerosis and hypertension.

Smokers have poorer lung functional reserve, lower alveolar septal elasticity, and more complications.

And this time the coronavirus does not discriminate between men and women, young and old, nor does it depend on official title, the population is universally susceptible! Old smokers need to give up their illusions!

To protect youth and reduce the tobacco reserve army

Many people are too addicted to quit smoking anymore, so at least don't smoke in your home, don't let your family follow you into second-hand smoke, and don't let your children learn how to smoke!

The inflection point of this wave of the epidemic is about to appear, so everyone should listen to Academician Zhong and stay at home for a few more days, so as not to let the work of epidemic prevention go down the drain.

I'm Dr. Howe in Imaging. Welcome!

Smoking, of course.

Who is more likely to be infected with the virus, smokers or non-smokers?

Novel coronaviruses are novel coronaviruses of the genus β. The main source of infection seen is patients with pneumonia caused by novel coronavirus infection. Respiratory droplet transmission is the main mode of transmission, but it can also be transmitted by contact.

Since it is a newly emerged virus, no population is immune to it and it is universally susceptible, meaning that all people are susceptible.

However, for the elderly and patients with underlying diseases, such as diabetes, hypertension, obesity, fatty liver disease, etc., as well as children and infants, because their immunity is weaker than that of normal people, they are susceptible to diseases, and once infected by the new coronavirus, the symptoms of the elderly and those with more underlying diseases are more serious, and deaths mostly occur in the above patients.

Therefore, both smokers and non-smokers are susceptible to the virus, but if their immunity is not the same, at the same risk of infection, the weaker immunity is definitely worse than the stronger immunity, and smokers, due to long term smoking, may have poorer lung function themselves, and are more likely to get the new coronavirus pneumonia, and once they get it, the condition is relatively severe, and this is something to be aware of. This is something to be aware of.

Precautions for people susceptible to the new coronavirus

It is recommended that the elderly and those with underlying diseases need to pay attention to strengthening protection, improving the body's ability to fight diseases and reducing the risk of infection. Try not to go out in the near future, go out must be well protected, the elderly go out to buy groceries, on the street must wear a mask, in the elevator room should also wear a mask, if you press the elevator buttons, it is best to wear gloves or take a toilet paper.

Drink more water, at least >1500ml of water a day, i.e., the amount of 3 bottles of mineral water, at home, wash your hands diligently, more exercise, exercise, indoor ventilation, can be disinfected with alcohol or chlorine disinfectant.

It is also recommended to eat more vegetables, fruits and foods rich in vitamins and proteins such as eggs and meat to replenish energy and improve immunity, but be careful that eggs and meat must be cooked.

In general, both smokers and non-smokers are susceptible to the new pneumonia virus, with those who have good immunity being more "resistant" than those who have weak immunity, but once infected, smokers may have more severe symptoms than non-smokers.

# Focus on new types of pneumonia and spread the word #

There are no statistics on the prevalence of new types of pneumonia in smokers and non-smokers, and it is currently believed thatAll people are susceptible to the new coronavirusThere is no difference between men and women, young and old, regardless of their physical state, the presence of comorbidities, etc., and there is certainly no difference between infections caused by smoking and those caused by not smoking.

Some people take it for granted that the lungs are less likely to be infected because they have a "toxic" barrier, but this is not true, and there are no studies on this.

You have to use your mouth to smoke, right? And the mucous membranes of the lips are the main entry point for the new coronavirus to attack. Hands, which may come into contact with objects contaminated with the virus, such as elevator buttons, door handles, door curtains, and after being contaminated with the virus, it doesn't die quickly, but mostly may survive for 2-5 days, and the collision of the hands with the lips when smoking creates theContact Transmission! This perspective says that smokers are more likely to be exposed and infected! Take off your mask too ......

Smoking is associated with many diseases, such as cardiovascular diseases, respiratory diseases and, of course, tumors, which do more harm than good! Smokers can also realize the discomfort caused by smoking when they wake up every day and click, click, click and spit.

If one is unfortunate enough to be infected with the novel coronavirus, there is no specific drug against the virus, and the treatment is mainly supportive and symptomatic. Can the lungs of smokers withstand the attack of the virus? Can the smoker's lungs withstand the attack of the virus? Can the patient survive? If you quit smoking for a few days, you will have less phlegm, try it.

Physiologically, smokers and non-smokers have the same likelihood of contracting the virus, don't we all have immune systems that don't recognize the virus, but smokers have an increased risk of contact transmission, droplet transmission, and are not as resistant to disease as non-smokers! Right? I'm @Dr. Liu Yongyi , thanks for reading!
