All over the world, governmental authorities and institutions are increasingly recommending the use of “non-medical” cloth masks to limit the risk of spreading COVID-19. In a recent publication, researchers from McMaster University and St. Joseph’s Hospital in Ontario explain that there is currently sufficient knowledge to justify this policy.
“Cloth does not stop isolated virions. However, most virus transmission occurs via larger particles in secretions, whether aerosol or droplets, which are generated directly by speaking, eating, coughing and sneezing,” the authors of the study said. “Every virus-laden particle retained in a mask is not available to hang in the air as an aerosol or fall to a surface to be later picked up by touch.”Supervised by researcher Catherine M.
According to the study, the rate of infections with influenza-like illnesses among health professionals wearing cloth masks was 2.3%, compared to 0.7% for medical masks. However, the results of this study were the subject of a second publication in the light of recent events linked to the COVID-19 pandemic.
