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

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

For an infection with this virus to occur, it should come into contact with the eyes, nostril, or mouth. This happens when droplets produced by an contaminated person (via speaking, coughing or sneezing), land on the face of another person. These infectious droplets can travel 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 one other way for an 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 exposure to infectious droplets. Nevertheless, face masks shortages are occurring because of interruptions within the supply 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 should not without problems. Once they grow to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals contact their face more often to adjust the masks, which increases the risk of infection if the hands are contaminated.

Material masks, though higher than nothing, have been shown to be less protective than medical-grade face masks.

We consider that face shields provide a better solution. There are a lot of types, however all use clear plastic material hooked up to a headpiece to cover the eyes, nose 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, can be cleaned after use, reused repeatedly, and for many people 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 restricted than for face masks. They can even be made at dwelling with objects from office provide and craft stores.

Every health care worker needs a face shield for protection at work. While face masks are nonetheless wanted in some situations, implementation of face shields will drastically reduce the necessity for face masks and prolong the restricted nationwide supply of masks. Engineers have produced designs for face shields which might be in 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 up to meet the demand by way of present manufacturers and recruitment of additional factories. Because the design is easy, large fast production would not be difficult.

As soon as the health care workpower is provided, distribution to the public ought to start, with a goal to provide a face shield to each particular person in the country. It ought to be worn anytime a person leaves their residence, while in any public place, and even at work. Although shelter-at-residence 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. Once each particular person is shielded, however, reducing restrictions on movement would carry less risk. Universal shielding could reduce reliance on social distancing since infectious droplets cannot reach the face of susceptible individuals. Handwashing, nonetheless, would remain essential to maintain individuals from infecting themselves with virus discovered on the arms after touching contaminated surfaces.
