Despite reducing the risk of Covid-19, tobacco still affects the health of smokers and the community. Nicotine patches will be helpful for anti-epidemic front-line doctors.
The SARS-CoV-2 virus that causes Covid-19 disease is the cause of pneumonia in severe cases. Therefore, many people believe that continued smoking during this time will increase the risk of respiratory effects.
However, a team of scientists at the Pitié-Salpêtrière Hospital in France has just published a new study showing that nicotine in cigarettes can reduce the risk of Covid-19 infection.
According to the Guardian, the research team asked 480 positive Covid-19 patients, of whom 350 were hospitalized and the rest were monitored at home. Results showed that in the hospitalized group, with an average age of 65, only 4.4% were regular smokers. In the home sit group, the average age of 44 years, 5.3% smoke.
Looking at age and gender, the team found that the percentage of smokers in the infected group was much lower than the rate in society. Specifically, the rate of smokers aged 44-53 in France is about 40%, and in the age group 65-75 is from 8.8-11.3%.
“Our general research shows that daily smokers are less likely to develop symptoms or have severe SARS-CoV-2 infection than is common in society.
The results are clear. The percentage of people hospitalized is 5 times lower and the number for non-hospitalized people is 4 times. This is a very rare ratio in medicine “, the team concluded.
Leading French neurologist Jean-Pierre Changeux, who reviewed the study, said that the nicotine in cigarettes could be a factor in the virus’s inability to invade cells and limit the spread in the body. Nicotine also reduces the overactive response of the immune system, a phenomenon that makes symptoms worse.
“The hypothesis is that when cell receptors bind to nicotine, the coronavirus cannot contact them, so nicotine prevents the virus from entering the cell,” Changeux told the Times.
This result is similar to a study published in China in March in the New England Journal of Medicine , showing that only 12.6% of 1,000 people infected with the virus in China smoke, while the average rate in this country is 28%
The Paris hospital group also released figures showing that out of more than 11,000 Covid-19 infected patients hospitalized, 8.5% were smokers. The average rate of smokers in France is 25.4%.
“It’s clear that something in cigarettes protects a smoker from coronavirus, but you should not come to the conclusion that you should smoke. There are many dangerous, toxic substances in cigarette smoke,” the team said warn those who think this result suggests more smoking.
Since then, researchers in France have proposed testing the nicotine patch on anti-epidemic patients and frontline health workers. This is a patch that attaches to the skin, providing nicotine to the brain to produce the same effect without smoking a real cigarette. This measure is also used to assist smokers.
