Let’s face it. As temperatures climb, wearing the face mask is getting harder and harder to wear. You constantly want to pull it down all the way or even just below your nose, but new guidelines from the CDC and research will make you think twice about that.
The CDC says your mask should be securely tightened to your face with no large gaps and it should cover both your nose and mouth. The nose is a key transmission point in the spread of this virus. According to a study from April reported in Nature Medicine two specific nose cell types, goblet and ciliated, have been identified as likely initial infection points for COVID-19.
Dr. Waradon Sungnak, one of the authors of the paper, said, “We found that the receptor protein — ACE2 — and the TMPRSS2 protease that can activate SARS-CoV-2 entry are expressed in cells in different organs, including the cells on the inner lining of the nose. We then revealed that mucus-producing goblet cells and ciliated cells in the nose had the highest levels of both these COVID-19 virus proteins, of all cells in the airways. This makes these cells the most likely initial infection route for the virus.”
Another more recent study from the University of North Carolina at Chapel Hill found that SARS-CoV-2 also infects the cells in your nose at a more intense level than the ones in your throat or lungs.
This is why the mask is essential but you have to be wearing it correctly. You also need to make sure the mask is made out of the right type of material.
