New coronavirus symptoms may be more severe in smokers, study says

According tomedia BGR reported that although anyone may be infected with the new coronavirus, but there are several groups of people are particularly vulnerable to develop into serious disease. Some studies, for example, have found that male patients over the age of 70 have a higher risk of death than others. Individuals with underlying diseases such as diabetes are also more likely to develop severe neoviral symptoms. And a new study has found that smokers, especially long-term smokers, are more likely to be infected with the new coronavirus than nonsmokers. According to Imperial College London, smokers are 14 percent more likely to end up with severe neo-coronavirus symptoms than nonsmokers.

New coronavirus symptoms may be more severe in smokers, study says

Smokers were 29 per cent more likely to report more than 5 COVID-19-related symptoms, while they were 50 per cent more likely to report more than 10 symptoms, including loss of smell, decreased appetite, tiredness, diarrhea, insanity, or muscle pain. In addition, smokers were 14 percent more likely to end up hospitalized due to severe symptoms of COVID-19 than nonsmokers.

A previous study published in the New England Journal of Medicine found that 12.3 percent of new coronavirus patients ended up in intensive care or on ventilators, compared with 4.7 percent of non-smokers who used a ventilator.

Studies have shown that the effect of the new coronavirus on smokers is more severe, because cigarette smoke increases the number of ACE2 receptors in the respiratory tract, and the new coronavirus tends to attach to these receptors. As LiveScience points out, this “makes organs vulnerable to new coronaviruses.”

Although tissue exposed to smoke contains more ACE2 receptors, the team was unable to determine which particular cells contained the receptor. By examining which proteins appear in which cells, the team found that ACE2 appears in cells in the lungs that process oxygen and carbon dioxide, known as alveoli type 2 cells. But mainly, the receptors appear in cells that secrete mucus-like fluids into the respiratory tract, known as cup-like cells and rod cells. The author found. Non-smokers carry most of the cup-like cells and rod cells in their noses and throats, but in smokers they also begin to accumulate in the lungs.

“What they’re suggesting is that when you smoke, you have an increased cup cell (in the lower respiratory tract), that’s for sure,” says Christenson. “
