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 individuals across the globe, has set the stage for an outbreak of proparts not seen in the final century.

For an infection with this virus to happen, it must come into contact with the eyes, nose, 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 feet, 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 another way for an infection to occur. Due to this fact, the key to avoiding 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 in the provide 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 last-ditch try and protect themselves while providing care. Even when plentiful, face masks aren't without problems. As soon as they develop into 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 an infection if the arms are contaminated.

Cloth masks, though higher 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 lots of types, however all use clear plastic materials hooked up to a headpiece to cover the eyes, nostril and mouth, thereby preventing infectious droplets from contacting these areas the place the virus can enter the body. They cover more of the face than masks and forestall 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 throughout the supply chains of a number of industries, the current provide is less restricted than for face masks. They can even be made at home with objects from office supply and craft stores.

Every health care worker wants a face shield for protection at work. While face masks are nonetheless needed in some situations, implementation of face shields will drastically reduce the need for face masks and extend the limited national supply of masks. Engineers have produced designs for face shields which might be within the public domain, and fabrication at scale is comparatively simple. To make sure that every health care worker has a face shield, production might want to ramp as much as meet the demand by means of present producers and recruitment of additional factories. Because the design is simple, massive rapid production wouldn't be difficult.

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