Breathing Is Enough: For the Spread of Influenza Virus and SARS-CoV-2 by Breathing Only.
Journal of Aerosol Medicine and Pulmonary Drug DeliveryVol. 33, No. 4. Published Online:28 Jul 2020

"A literature search showed that there is a strong scientific rationale and evidence that viruses are very efficiently spread through aerosols by the patient's breathing only. It is not necessary for the patient to cough or sneeze."

"Masks should completely cover the nose and mouth and fit snugly against the sides of face without gaps."

"our nose is prime real estate for the coronavirus. It’s where the coronavirus infection settles in first before traveling to the lungs, according to new research by Carolina scientists...  

The study results, published in the journal Cell by researchers at the UNC Gillings School of Global Public Health and the UNC School of Medicine, indicate that the virus firmly establishes itself inside the nose first. Then, in some cases, people breathe the virus into their lungs where it may lead to more serious disease, including potentially fatal COVID-19 pneumonia."

"What’s more, the study suggests that people are probably releasing a higher concentration of the COVID-19 virus when breathing out of their noses, rather than exhaling out of their mouths."

"...The SARS-CoV-2 virus lives in people’s nasal passages. When an infected person exhales, they release viral particles from their nose into the air. (And notice we’re talking about a basic exhale, not a cough or sneeze. Even the simple act of breathing releases particles.) A mask -- worn over the mouth and nose -- helps to keep these infectious particles from becoming airborne and reaching others."
