the doctor-the virologist, senior research fellow, Centre of epidemiology and Microbiology named Gamalei Victor Larichev explained why to protect against coronavirus COVID-19 construction respirator is a more effective tool than a medical mask.
Respirators filter the air better: the material from which they are made, are capable of keeping smaller particles, including dust. A dust mask does not protect, reminds RIA Novosti.
the Virus spreads in the form of droplets (by sneezing, coughing, talking). Masks are able to hold these drops, so they are also effective against infection. But the respirator fits snugly to the face, noted virologist.
