Face Shields Are An Achievable Way To Provide Protections That COVID-19 Demands

The COVID-19 pandemic presents huge challenges. A newly emerged virus to which the world’s inhabitants has no immunity, coupled with the rapid movement of individuals throughout the globe, has set the stage for an outbreak of proportions not seen within the last century.

For infection with this virus to happen, it must come into contact with the eyes, nostril, or mouth. This occurs when droplets produced by an contaminated individual (via talking, coughing or sneezing), land on the face of one other person. These infectious droplets can journey up to 6 ft, which is the reason to promote social distancing. Touching a surface that's contaminated with infectious droplets and then touching one’s own eyes, nostril or mouth, is one other way for infection to occur. Subsequently, the important thing to avoiding infection is to have these areas of the face covered.


In hospitals, face masks and goggles are typically used to stop publicity to infectious droplets. Nevertheless, 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 compelled to resort to scarves and bandannas in a final-ditch try and protect themselves while providing care. Even when plentiful, face masks are usually not with out problems. Once they turn out to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some people touch their face more usually to adjust the masks, which will increase the risk of infection if the hands are contaminated.

Material masks, although 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 various types, but all use clear plastic materials connected to a headpiece to cover the eyes, nostril and mouth, thereby preventing infectious droplets from contacting these areas where the virus can enter the body. They cover more of the face than masks and prevent the wearer from touching their face. Importantly, face shields are durable, could be cleaned after use, reused repeatedly, and for many individuals are more comfortable than face masks. Because these shields are reusable and are diversified throughout the provision chains of a number of industries, the current provide is less limited than for face masks. They'll even be made at residence with items from office provide and craft stores.

Every health care worker wants a face shield for protection at work. While face masks are still needed in some situations, implementation of face shields will greatly reduce the need for face masks and lengthen the restricted nationwide provide of masks. Engineers have produced designs for face shields that are within the public domain, and fabrication at scale is relatively simple. To ensure that every health care worker has a face shield, production will need to ramp as much as meet the demand via current manufacturers and recruitment of additional factories. Because the design is simple, massive rapid production would not be difficult.

Once the health care workpressure is provided, distribution to the public ought to begin, with a goal to provide a face shield to each person in the country. It should be worn anytime an individual leaves their dwelling, while in any public place, and even at work. Though shelter-at-house approaches are needed to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are willing to maintain such measures. As soon as each individual is shielded, nevertheless, reducing restrictions on movement would carry less risk. Universal shielding may reduce reliance on social distancing since infectious droplets can not attain the face of susceptible individuals. Handwashing, however, would stay essential to maintain folks from infecting themselves with virus discovered on the arms after touching contaminated surfaces.
