A recent study warned against leniency in wearing the mask, or the so-called “half-mask” phenomenon, considering that this increases the risk of the virus entering the body without achieving complete protection.
“It’s like wearing your pants with just one leg. A mask or other face mask should cover your mouth and nose,” said Dr. Frederick Davis, co-chief of emergency medicine at Northwell Health / Long Island Hospital in New York.
A study from the University of North Carolina (UNC) published in the journal Cell indicated that the new Corona virus first tends to penetrate and infect the nasal cavity, and in some cases it can be inhaled into the lungs, where it can develop into pneumonia, according to the study.
The UNC research team used receptor cells to track the Sars-CoV-2 virus and reveal its pathway in the respiratory system. And they indicated that the virus infected the nasal passages more than others.
According to the New York Post, the published report revealed that the virus targeted the ACE2 receptor (angiotensin converting enzyme 2), as a means of entering the body. The report said that ACE2 receptors are more abundant in the tissue of the lining of the nose and less widespread in the lower parts of the respiratory system.
One of the authors participating in the study said that this may explain why the nasal part of the upper respiratory tract is more susceptible to infection, “Covid-19”, and why wearing a mask is important in the end.
“Unfortunately, SARS-CoV-2 has learned to evade the natural defense mechanisms of the nose, and this receptor is used to infect the cells of the lining of the nose,” said co-lead author of the study, Dr. Richard Boucher, Director of the Marsico Lung Institute at the UNC School of Medicine.
He added: “The viruses that are produced in the nose can spread to the olfactory tissues on the roof of the nose, leading to loss of the sense of smell, to the mouth, injury to the salivary glands, and the symptoms of dry mouth, and to the lung, where it results in pneumonia with shortness of breath and death already.” .
