The COVID-19 pandemic presents enormous challenges. A newly emerged virus to which the world’s inhabitants has no immunity, coupled with the fast movement of people across the globe, has set the stage for an outbreak of proportions not seen in the last century.
For infection with this virus to happen, it must come into contact with the eyes, nose, or mouth. This happens when droplets produced by an contaminated person (through speaking, coughing or sneezing), land on the face of one other person. These infectious droplets can travel as much as 6 feet, which is the reason to promote social distancing. Touching a surface that is contaminated with infectious droplets after which touching one’s own eyes, nose or mouth, is one other way for 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 forestall exposure to infectious droplets. Nevertheless, 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 forced to resort to scarves and bandannas in a final-ditch try and protect themselves while providing care. Even when plentiful, face masks will not be with out problems. As soon as they turn into wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals contact their face more typically to adjust the mask, which increases the risk of infection if the fingers are contaminated.
Material 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 many types, however all use clear plastic materials connected to a headpiece to cover the eyes, nose 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 stop the wearer from touching their face. Importantly, face shields are durable, might 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 provide is less restricted than for face masks. They can even be made at house with items from office supply and craft stores.
Every health care worker wants a face shield for protection at work. While face masks are still needed in some conditions, implementation of face shields will tremendously reduce the need for face masks and lengthen the restricted nationwide provide of masks. Engineers have produced designs for face shields that are 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 through current producers and recruitment of additional factories. Because the design is simple, large speedy production would not be difficult.
Once the health care workdrive is provided, distribution to the public ought to start, with a goal to provide a face shield to every individual 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-dwelling approaches are wanted to “bend the curve” of this pandemic, the ensuing societal disruption limits the time that political leaders are keen to maintain such measures. Once every 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 reach the face of inclined individuals. Handwashing, nevertheless, would stay essential to maintain people from infecting themselves with virus discovered on the fingers after touching contaminated surfaces.
