The COVID-19 pandemic presents monumental challenges. A newly emerged virus to which the world’s population has no immunity, coupled with the fast movement of individuals across the globe, has set the stage for an outbreak of proportions not seen within the last century.
For an infection with this virus to happen, it must come into contact with the eyes, nostril, or mouth. This happens when droplets produced by an contaminated individual (via talking, coughing or sneezing), land on the face of another person. These infectious droplets can journey up to 6 toes, which is the reason to promote social distancing. Touching a surface that's contaminated with infectious droplets after which touching one’s own eyes, nostril or mouth, is another way for infection to occur. Therefore, the key to avoiding infection is to have these areas of the face covered.
In hospitals, face masks and goggles are typically used to prevent publicity to infectious droplets. Nevertheless, face masks shortages are occurring because of interruptions in the supply chain, which is deeply rooted in China and disrupted by the pandemic. Some health care workers have been pressured to resort to scarves and bandannas in a final-ditch attempt to protect themselves while providing care. Even when plentiful, face masks should not with out problems. Once they become wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals touch their face more usually to adjust the masks, which will increase the risk of an infection if the hands are contaminated.
Cloth masks, though higher than nothing, have been shown to be less protective than medical-grade face masks.
We imagine that face shields provide a greater solution. There are numerous types, however all use clear plastic material hooked up to a headpiece to cover the eyes, nose and mouth, thereby stopping infectious droplets from contacting these areas where the virus can enter the body. They cover more of the face than masks and forestall the wearer from touching their face. Importantly, face shields
are durable, may be cleaned after use, reused repeatedly, and for many individuals are more comfortable than face masks. Because these shields are reusable and are diversified across the provision chains of multiple industries, the present provide is less limited than for face masks. They can even be made at dwelling with gadgets from office supply and craft stores.
Each health care worker wants a face shield for protection at work. While face masks are still needed in some conditions, implementation of face shields will tremendously reduce the need for face masks and extend the limited nationwide provide of masks. Engineers have produced designs for face shields that are within the public domain, and fabrication at scale is comparatively simple. To ensure that each health care worker has a face shield, production might want to ramp as much as meet the demand by way of current manufacturers and recruitment of additional factories. Because the design is simple, large rapid production would not be difficult.
As soon as the health care workdrive is provided, distribution to the general public should start, with a goal to provide a face shield to every individual within the country. It ought to be worn anytime a person leaves their house, while in any public place, and even at work. Although shelter-at-residence approaches are wanted to "bend the curve" of this pandemic, the following societal disruption limits the time that political leaders are keen to maintain such measures. Once every particular person is shielded, however, reducing restrictions on movement would carry less risk. Universal shielding may reduce reliance on social distancing since infectious droplets can't attain the face of susceptible individuals. Handwashing, nonetheless, would remain essential to keep people from infecting themselves with virus found on the arms after touching contaminated surfaces.
