The COVID-19 pandemic presents huge challenges. A newly emerged virus to which the world’s population has no immunity, coupled with the fast movement of people across the globe, has set the stage for an outbreak of proparts not seen within the final century.
For an infection with this virus to happen, it should come into contact with the eyes, nostril, or mouth. This occurs when droplets produced by an contaminated individual (via speaking, coughing or sneezing), land on the face of one other person. These infectious droplets can journey as much as 6 feet, which is the reason to promote social distancing. Touching a surface that’s contaminated with infectious droplets and then touching one’s own eyes, nose or mouth, is another way for infection to occur. Subsequently, the key to avoiding an 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. However, face mask shortages are occurring because of interruptions within the provide 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 last-ditch try to protect themselves while providing care. Even when plentiful, face masks are usually not without problems. As soon as they turn out to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some people contact their face more usually to adjust the masks, which increases the risk of infection if the arms are contaminated.
Material masks, though better 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 lots of types, but all use clear plastic material attached 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 stop the wearer from touching their face. Importantly, face shields are durable, will 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 availability chains of multiple industries, the current supply is less limited than for face masks. They’ll even be made at house with gadgets from office provide and craft stores.
Each health care worker needs a face shield for protection at work. While face masks are nonetheless needed in some conditions, implementation of face shields will greatly reduce the necessity for face masks and prolong the limited national provide of masks. Engineers have produced designs for face shields which are in the public domain, and fabrication at scale is relatively simple. To ensure that every health care worker has a face shield, production might want to ramp as much as meet the demand via present producers and recruitment of additional factories. Because the design is easy, massive speedy production wouldn’t be difficult.
As soon as the health care workpower is supplied, distribution to the general public ought to begin, with a goal to provide a face shield to every person in the country. It must be worn anytime a person leaves their dwelling, while in any public place, and even at work. Although shelter-at-residence approaches are needed to “bend the curve” of this pandemic, the following societal disruption limits the time that political leaders are keen to maintain such measures. As soon as each person is shielded, however, reducing restrictions on movement would carry less risk. Common shielding may reduce reliance on social distancing since infectious droplets cannot attain the face of susceptible individuals. Handwashing, however, would remain essential to maintain folks from infecting themselves with virus found on the hands after touching contaminated surfaces.
