Coronavirus (COVID19) and smoking

Covid19 and Smoke

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.

French researchers test nicotine patches on patients with coronavirus.
French researchers suggest nicotine can protect against coronavirus,
which indicates that of the approximately 11 thousand patients hospitalized with coronavirus infection COVID19, in early April, only 8,5% were smokers (this is about 935 patients).

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.

Also The Ministry of Health of the Russian Federation indicated that smokers are easier to tolerate COVID19 have no reason.

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).

⚡ Smoking and coronavirus. New data.

No smoke, will be vacant

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 in China, where more than 50% of men are smokers among the male population, and 3% of the female population are female smokers. According to China Center for Disease Control and Prevention

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. Source

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?

Think about your health. Health to you.
