Face Shields Are An Achievable Way To Provide Protections That COVID-19 Demands
For infection with this virus to occur, it must come into contact with the eyes, nose, or mouth. This happens when droplets produced by an contaminated individual (via talking, coughing or sneezing), land on the face of one other person. These infectious droplets can journey up to 6 feet, which is the reason to promote social distancing. Touching a surface that is contaminated with infectious droplets and then touching one’s own eyes, nose or mouth, is one other way for an infection to occur. Due to this fact, 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 exposure to infectious droplets. Nonetheless, face mask 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 attempt to protect themselves while providing care. Even when plentiful, face masks aren't without problems. As soon as 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 mask, which will increase the risk of infection if the arms are contaminated.
Fabric masks, although better 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 many 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, could be cleaned after use, reused repeatedly, and for many individuals are more comfortable than face masks. Because these shields are reusable and are diversified across the provision chains of multiple industries, the current supply is less restricted than for face masks. They will even be made at home with items from office supply and craft stores.
Every health care worker needs a face shield for protection at work. While face masks are nonetheless needed in some conditions, implementation of face shields will enormously reduce the need for face masks and extend the restricted national supply of masks. Engineers have produced designs for face shields which might be in the public domain, and fabrication at scale is relatively simple. To make sure 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 straightforward, massive rapid production wouldn't be difficult.
Once the health care workforce is provided, distribution to the public ought to start, with a goal to provide a face shield to each individual in the country. It should be worn anytime an individual leaves their house, while in any public place, and even at work. Though shelter-at-dwelling approaches are needed to "bend the curve" of this pandemic, the following societal disruption limits the time that political leaders are willing to sustain such measures. Once every person is shielded, nonetheless, reducing restrictions on movement would carry less risk. Universal shielding may reduce reliance on social distancing since infectious droplets can't attain the face of inclined individuals. Handwashing, nevertheless, would remain essential to maintain individuals from infecting themselves with virus discovered on the arms after touching contaminated surfaces.
