Scientists discover the link between smoking and infection with Corona

Numerous studies have confirmed that smokers usually suffer from respiratory health problems, especially in the lungs, because the tar, nicotine and other substances in tobacco block the airways and cause significant and long-term damage to the body’s organs.

Since the first day of the emergence of the new Corona virus, scientists began to search for a link between it and smoking, considering that both enter the body through the portal of the respiratory system.

And recently, researchers from the University of California in Los Angeles found an indirect link between smoking and the epidemic, as they concluded that exposure to cigarette smoke makes airway cells more vulnerable to infection with the emerging corona virus.

The researchers obtained the cells lining the airway from 5 individuals who were not infected with “Covid 19”, and exposed some cells to cigarette smoke in test tubes, and then released the Corona virus on all cells.

The researchers said in the journal “Cell Steam Cell”, that “when compared to cells that were not exposed to smoke, cells exposed to smoke were two or 3 times more likely to be infected with the virus.”

An analysis of each individual’s airway cells also showed that cigarette smoke reduces the immune response to the virus.

“If air passages are considered like high walls protecting a castle, smoking cigarettes is like making holes in these walls,” Brigitte Gombert, who was involved in the research, told Reuters.

She added: “Smoking reduces the natural defenses and this allows the virus to enter and take over cells.”
