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 fast movement of individuals throughout the globe, has set the stage for an outbreak of proparts 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 infected person (through speaking, coughing or sneezing), land on the face of another person. These infectious droplets can travel 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 one other way for an 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 prevent publicity to infectious droplets. Nonetheless, face mask 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 forced to resort to scarves and bandannas in a final-ditch attempt to protect themselves while providing care. Even when plentiful, face masks will not be without problems. As soon as they turn out to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals touch their face more often to adjust the mask, which increases the risk of an infection if the arms are contaminated.

Fabric 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 various types, but all use clear plastic material attached to a headpiece to cover the eyes, nostril 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 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 provision chains of multiple industries, the present supply is less limited than for face masks. They can even be made at home with items from office provide and craft stores.

Every health care worker wants a face shield for protection at work. While face masks are nonetheless wanted in some conditions, implementation of face shields will vastly reduce the need for face masks and prolong the limited national provide of masks. Engineers have produced designs for face shields which might be within the public domain, and fabrication at scale is relatively simple. To make sure that every health care worker has a face shield, production might want to ramp up to meet the demand by way of current manufacturers and recruitment of additional factories. Because the design is straightforward, massive speedy production would not be difficult.

Once the health care workdrive is equipped, distribution to the general public ought to begin, with a goal to provide a face shield to each particular person in the country. It must be worn anytime an individual leaves their dwelling, while in any public place, and even at work. Though shelter-at-house approaches are wanted to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are prepared to sustain such measures. As soon as every person is shielded, nevertheless, reducing restrictions on movement would carry less risk. Universal shielding may reduce reliance on social distancing since infectious droplets can not reach the face of susceptible individuals. Handwashing, nonetheless, would remain essential to keep people from infecting themselves with virus found on the hands after touching contaminated surfaces.
