THE COVID-19 PANDEMIC HAS UPENDED OUR DAILY LIVES. MORE THAN EVER, WE MUST THINK ABOUT HOW TO STAY SAFE AND PROTECT OUR LOVED ONES.
TRADITIONAL METHODS HAVE NOT EFFECTIVELY PREVENTED TRANSMISSION.
Personal protective equipment (PPE) is critical in the fight against COVID-19 transmission. Scientists have documented three ways of transmission of COVID-19: through contaminated hands or fomites coming into contact with the body's exposed mucal membranes (eyes, nose, and mouth), through large droplets expelled from the nose and mouth (caused by talking, sneezing, coughing, etc.), and by contaminated micro-particles expelled from the body in the form of aerosol mists. These contaminated airborne micro-particles can stay suspended in the air, travel well beyond 6 ft., and be easily inhaled. Experts are divided on the general effectiveness of masks. There seems to be an emerging consensus that they are more effective at preventing an infected person from spreading airborne pathogens than they are to protect the wearer from inhaling them. This is due to the fact that most face masks don't create an air-tight seal around the nose and mouth. When you breathe in a mask, some of the air comes from the openings around the mask instead of passing through the filtering materials. Masks also leave the eyes exposed, leaving another vulnerable entry point at risk. Conventional face shields do block larger droplets from the eyes, but they may not offer adequate protection from contaminated aerosols.
