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

The COVID-19 pandemic presents enormous challenges. A newly emerged virus to which the world’s population has no immunity, coupled with the rapid movement of individuals across the globe, has set the stage for an outbreak of proportions 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 person (via speaking, coughing or sneezing), land on the face of one other person. These infectious droplets can travel as much as 6 ft, which is the reason to promote social distancing. Touching a surface that is contaminated with infectious droplets and then touching one’s own eyes, nostril or mouth, is another way for infection to occur. Due to this fact, the important thing to avoiding an infection is to have these areas of the face covered.


In hospitals, face masks and goggles are typically used to forestall publicity to infectious droplets. Nonetheless, 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 last-ditch attempt to protect themselves while providing care. Even when plentiful, face masks should not with out problems. Once they grow 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 increases the risk of infection if the fingers are contaminated.

Cloth masks, although better than nothing, have been shown to be less protective than medical-grade face masks.

We believe that face shields provide a greater solution. There are many types, however all use clear plastic materials 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 stop the wearer from touching their face. Importantly, face shields are durable, will 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 supply chains of a number of industries, the current provide is less restricted than for face masks. They will even be made at dwelling with gadgets from office supply and craft stores.

Each health care worker needs a face shield for protection at work. While face masks are nonetheless wanted in some conditions, implementation of face shields will tremendously reduce the need for face masks and lengthen the limited nationwide provide of masks. Engineers have produced designs for face shields which can be in the public domain, and fabrication at scale is relatively simple. To ensure that each health care worker has a face shield, production might want to ramp as much as meet the demand via current manufacturers and recruitment of additional factories. Because the design is easy, large rapid production would not be difficult.

As soon as the health care workforce is equipped, distribution to the general public ought to begin, with a goal to provide a face shield to every particular person in the country. It ought to be worn anytime a person leaves their home, while in any public place, and even at work. Though shelter-at-residence approaches are wanted to "bend the curve" of this pandemic, the following societal disruption limits the time that political leaders are willing to sustain such measures. As soon as each particular person is shielded, nonetheless, reducing restrictions on movement would carry less risk. Universal shielding might reduce reliance on social distancing since infectious droplets can't reach the face of vulnerable individuals. Handwashing, nonetheless, would remain essential to maintain folks from infecting themselves with virus discovered on the fingers after touching contaminated surfaces.
