Smoking and coronavirus. Updated data for May 2020.
Increasingly, there is evidence that the coronavirus bypasses smokers and it is not easy for the smoker to get the coronavirus. Why this happens remains a mystery. Toli tobacco smoke neutralizes the virus, felts nicotine itself somehow blocks the virus and its reproduction.
Let me remind you, this is about traditional smoking, and not about analogues and electronic versions.
Further there is no less interesting studies according to the Pity-Salpetriere Hospital in Paris. Of the 340 hospitalized patients, 4,1% were smokers (14 patients), and of the 139 outpatients, 6,1% were smokers (8 patients). The average age of hospitalized patients was 66 years, ambulatory patients 44 years.
For smokers, it looks soothing. However, the World Health Organization (WHO) clearly indicates that smoking cannot protect against coronavirus, on the contrary, it provokes the development of a severe stage of the disease COVID-19. https://twitter.com/WHO/status/1259868599428108288
My opinion is that smokers have no benefit over coronavirus infection. Neither in the possibility of infection, nor in the possibility of a mild course of the disease. There are smokers who smoke little, but for many years and decades, there are people who combine smoking and physical activity, among smokers there are people who lead a lifestyle similar to a healthy lifestyle, including proper nutrition and who do not have excess body weight. Of course, such smokers have a much higher chance of getting COVID in a mild form than heavy smokers with existing chronic smoking-related diseases, especially among obese people.
The possibility of reducing the infectious dose of the pathogen SARS-CoV2, of course, is. The theory of the “benefits of smoking” in coronavirus is apparently based on that. Due to toxic chemical compounds contained in tobacco smoke, the pathogen concentration decreases and the infectious dose of the coronavirus becomes minimal, which in some cases does not cause disease or COVID19 is asymptomatic or mild. However, in a pandemic and highly contagious (contagious), such statements are more like a one-time winning lottery ticket than permanent protection against infection. Also, a winning ticket with a growing number of diseases can be considered an individual feature of the perception of a new coronavirus, and smoking here has almost no effect on the course of the disease.
And finally, about smoking and coronavirus - look at smoker's lungs in google images. As they say (no commets).
According to constantly updated and researched data on COVID19, coronavirus infection is a systemic disease.
This means that the whole body can be affected, not just the lungs, and with inflammatory processes of the upper respiratory tract as with respiratory diseases, the infection can develop further throughout the body. The new virus is so unpredictable that any course of the disease depends on the immune system and the characteristics of the body. The mild and moderate course of the disease is largely associated with immunity and general condition, along with the absence of diseases in which the possibility of complications increases many times.
Diseases in which the risk of complications increases (chronic diseases: hypertension, vascular disease, diabetes, asthma, oncology, obesity). People with cardiovascular disease are at increased risk for tolerance to this infection.
In one of the possible complications of coronavirus infection, blood cells responsible for oxygenation (oxygenation) of the body are affected, the virus absorbs hemoglobin in red blood cells - red blood cells. As a result of this, it becomes impossible to transport oxygen to cells and tissues, then a negative process, due to the impossibility of gas exchange, leads to an inflammatory process in the lungs, and this can develop rapidly, with a sharp deterioration of the condition, which can lead to death. On CT (computed tomography), a decrease in airiness and the development of pulmonary fibrosis may appear as a “frosted glass” effect.
The situation with complications and the course of the disease COVID-19 is so unpredictable and individual that any outcome is possible, recovery from asymptomatic and unnoticed to severe complications and the most sad.
All negative processes caused by the SARS-CoV-2 coronavirus can develop before the appearance of irreversible consequences completely, without any special symptoms and an increase in temperature above 38.0 °. Symptoms of COVID19: fatigue, palpitations, dyspnea, drowsiness, headache, muscle pain with a general low-grade temperature of 37.1 ° -38.0 °. Coronavirus damage to the lungs that occurs after the middle and mild course of the disease is difficult to track due to the satisfactory condition of the infected person, as well as due to the similarity of symptoms with coronavirus infection and sensations after smoking in particular - shortness of breath, increased heart rate and headache, weakness, decreased and a weakening or even loss of smell and taste (one of the most frequently occurring symptoms, but not an obligatory symptom of coronavirus infection). Particularly problematic can be diagnosed and lead to an advanced stage of a new disease, its wave-like course. After mild symptoms of malaise, the improvement phase begins, lasting on average several days, while body temperature can normalize, after elevated, then health can rapidly deteriorate due to viral infection of the focal inflammation. If the condition worsens, you should immediately consult a doctor. So, as with a viral infection of the body, immunity is significantly reduced, in addition to a viral infection, a bacterial infection in the form of pneumococcus and other “cocci” - staphylococcus, streptococcus, can join. and others, which can cause bacterial pneumonia.
Coronavirus penetrates and develops in the body through the ACE2 and CD147 proteins. The virus enters the cell through the membrane proteins ACE2, there is also research that SARS-CoV2 can bind to the recombinant protein CD147 by triggering its processes leads to viral inflammation of the affected organ. Lesions can cause acute respiratory distress syndrome (lung infiltration - the accumulation of cellular elements in the body tissues mixed with blood and lymph together with hypoxemia - a decrease in oxygen content), pulmonary edema and myocarditis (damage to the heart muscle - myocardium, sepsis). These are possible complications of a new coronavirus infection (COVID-19) which for a non-smoker who leads a healthy lifestyle is really difficult and requires significant body forces to recover and suppress the infection, together with the right treatment. An effective treatment for coronavirus today is plasma transfusion with antibodies to coronavirus to a patient from a sick and recovered person.
For optimists who think that they “disinfect” the airways by smoking and (despite its harm) smoke the surface of their lungs with a “nicotine coating” that “disinfects” and that the virus cannot attach. Think about these facts:
Smokers are more likely to have respiratory problems.
Smokers have reduced immunity (even people with good health from birth, immunity can “walk” depending on the amount smoked)
Smokers usually have concomitant diseases caused by smoking and most likely diseases in the chronic stage that they “transferred” due to smoking from the acute stage to the chronic one.
Smoker's bronchitis, predisposition to emphysema, COPD (Chronic Obstructive Pulmonary Disease), cancer, and not only lung, do not add health and resistance to infectious diseases. especially viral!
Hypoxemia - oxygen deficiency of the body, a decrease in the functioning of vital functions and, as a result, forcing the body to work in an increased, compensatory mode to replenish homeostasis (self-regulation of the body to normalize functioning).
Also an indirect indicator is mortality from COVID19, where the male part predominates, even in South Korea, where women account for about 60% of the total number of cases, more men than women died from COVID-19.
Men smoke more than women, which contributes to an increase in the incidence of respiratory diseases. According to Business Insider

And another opposite hypothesis on European Respiratory Journalthat smoking and lung diseases (usually caused by smoking), increase the level of ACE2 enzymes (membrane proteins) in the airways, which allow the coronavirus to access lung cells, which can cause complications of the disease.

In any case, you do not need to be an expert to understand. that in the situation with coronavirus infection, with all the possible advantages of nicotine and “smoking,” the likelihood of complications is much higher than in a non-smoker person, taking into account concomitant diseases caused by smoking.

Why play roulette - on the one hand, reassure yourself that nicotine helps to cope with coronavirus, on the other hand, realize the possibility of infection due to smoking years of lungs. Common sense dictates that if a smoker picks up a coronavirus, what are his chances of getting off easily compared to a non-smoker?
April 2020. The world will forever remember this time. Viral infection of SARS-C0V-2 caused by COVID-19 disease.
The complications caused by a coronavirus infection are not limited to atypical pneumonia, there is evidence that the virus causes brain damage, can penetrate the gastrointestinal tract while remaining there, causing deterioration and various ailments. There is already evidence that coronavirus does not cause pneumonia, as is commonly believed, but a more specific lung lesion that literally destroys lung tissue. There are confirmed cases of recovery after COVID-19, when the lungs are preserved at 60% of the initial volume. One recovered lung volume remained at 30% of the original.
The new strain of coronavirus that appears is quite unpredictable and still poorly understood. At the same time, what will be the course of the disease when infected with coronavirus, it remains only to pray and believe in a favorable outcome. There are no prerequisites for predicting the course of the disease. Long-livers have cases of recovery, and unfortunately there are facts of the death of quite young people who do not suffer from any pathologies.
And where is smoking?
Any smoker understands that smoking is poisoning the body with various poisons. The first intoxication and poisoning is taken by the respiratory system: throat, vocal cords, bronchi, trachea, lungs. Coronavirus infection occurs in most cases into the body by airborne droplets, settling mainly in the nasopharynx. It is enough just to take a breath to be infected (there are other options for infection with coronavirus, we are considering an airborne droplet). It would seem that everything is so bad, and publicly available statistics indicate that smoking does not affect the incidence of COVID-19 so much. According to the European Journal of Allergy and Clinical Immunology Of the 140 infected with coronavirus infection (COVID-19) in Wuhan, only two were smokers. And according to the history of the first patients with coronavirus infection in Wuhan and Guangzhou 12,6% were smokers, and 1,9% were former smokers, the remaining 85,4% of those infected were non-smokers.
What does all this mean? What are smokers less likely to get coronavirus? According to the statistics currently presented, this seems to be true. However, there is still a lot of unaccounted data:
1. The above statistics, although official, are insufficient for the final conclusion about the effects of smoking and the incidence of coronavirus infection. For example, those infected at the beginning of the outbreak of the epidemic, out of 50 people infected, 10 will die, this is 20% mortality, and with an increase in infected to 1000, the mortality rate will be 50, resulting in a mortality of 5% for the same disease.
To obtain accurate data, larger statistics are needed.
2. Smokers in China, according to the most minimal estimates of about 350 million people, this is the fourth part of the country's population, the number tested on COVID-19 in China based on public statistics is not. Accordingly, it is impossible to present a real threat to smokers. However, common sense suggests otherwise.
3. The actual numbers of patients can be 10 times higher than in official statistics on morbidity. Moreover, this can be for various reasons, from hiding real data, to testing only severe and moderate cases of the course of the disease, which falls into the statistics. Asymptomatic patients are most likely not taken into account, again due to the excessive workload of medical facilities. There are simply no time left for asymptomatic patients. Also asymptomatic and patients of moderate and even severe severity, most are at home and treated / recover at home. Most likely, such patients are not taken into account, since the coronavirus infection in them passes as usual ARVI.
4. Mortality statistics in different countries are markedly different. For smokers and former smokers, there is also no clear understanding and separation, even if such records are kept while it is not in the general statistics of morbidity. Somewhere they test everyone without exception, somewhere selectively, somewhere only with symptoms.

Smokers are in a special risk zone, former smokers too, although of course to a lesser extent from real smokers. Moreover, there is no need to wait for special statistics, common sense says that there is no smoke without fire. Moreover, smokers include not only smokers of cigarettes, but also smokers on a regular basis of vapes, electronic cigarettes, hookahs and other tobacco heating systems to obtain a personal dose of nicotine.
During the outbreak in China, no one believed in such an outcome. You never know what viruses are, especially when patients are estimated at ten people.
November 17, 2019 - the first patient
December 15, 2019 - 27 patients
December 17, 2019 - 60 patients
January 1, 2020 - 381 cases
March 11 2020
WHO announces worldwide pandemic of coronavirus infection COVID-19 caused by SARS-CoV-2 coronavirus.
Most countries on earth are infected, in some European countries the number of infected people is growing exponentially, while the number of deaths due to coronavirus infection is increasing.
April 3, 2020 - a figure of 1.000.000 one million infected with COVID-19 is recorded worldwide
April 17, 2020 - 2,223,240, more than two million two hundred twenty three thousand infected around the world
November 17-April 17, over 5 months more than 2 million infected, more than 152 thousand dead, only according to official statistics. Real data can be much more.
Why quit smoking now and it should work out.
In fact, you can give a lot of reasons, I will describe those that are your trump cards right now.
Quarantine and self-isolation. Smoking is problematic anywhere, and in conditions of limited mobility, toxic compounds are retained in the body for a longer time. You also smoke less or less, and there is more harm to the body.
Quarantine as an opportunity to endure nicotine hunger is the most difficult option. After going through the abstinence phase of dependence on nicotine, you most likely will not want to smoke, the desire to smoke will be minimal. This desire can be dealt with without much effort. Such a cessation of smoking is quite difficult, but real.
And if you can not smoke while the nicotine withdrawal has gone, you will appreciate your abstinence, and later negative memories will fade and you will simply be happy that you finally got rid of the destructive habit.
Think about what will happen next if you suddenly become infected with a coronavirus (I strongly wish you to avoid this). At
it is not recommended to smoke any respiratory diseases, acute respiratory viral infections and influenza for a quick recovery, and with coronavirus infection I think everything is clear.
What to do if after throwing, some people begin to clear the body and cough, shortness of breath, in some cases bronchitis, etc. After all, you can confuse these symptoms with a coronavirus infection. Yes it is.
But if there is a risk of getting infected, it is better to stop smoking during the course of the disease, treatment, and after recovery?
All negative consequences after quitting smoking are temporary. The appearance of such consequences is strictly individual and depends on the length of smoking, the number of cigarettes smoked, lifestyle, age and general condition of the body.
Everyone decides for himself when he should stop smoking and whether it is worth it. If you are unable to quit smoking, do not want to, are afraid, put it off, or for whatever reason put it off, try to smoke less.
See how to recover from quitting smokingtaking into account quarantine measures and isolation.
Moreover, on self-isolation, the risk of infection is minimized, and recovery will be soft and smooth.
The origin of the virus is still in question. Also, new data constantly appear on the virus damage not only to the lungs but also to other organs, the appearance of new symptoms of coronavirus (rash, diarrhea, lack of temperature during lung damage), obviously this is due to the mutation of the virus and individual human immune responses to infectious invasion. From now on, the possibility of the emergence of new viruses and the emergence of pandemics or even syndromes in humanity will always be associated with the fear of contracting a deadly disease.
But in any case, the first to meet and try to block the infection is immunity. It is impossible to have good immunity and smoke. Even if you smoke and try to lead a lifestyle close to healthy.
