Now, medical experts agree thatwearing a face covering is one of the best ways to slow down the spread of coronavirus, especially if it is done in combination with social distancing and a regular hand washing. And although some can disagree on what type is the best global, it also becomes clear thatcertain types of face coatings May be less effective. According to a recent study,Face shields will not protect you from COVID as well as traditional masks..

The new research, which has just published in the newspaperFluid physics, find that, while face shields are able to stop large droplets expelled from coughing, sneezing or strong discussions, theyDo not completely keep potentially contaminated aerosols To travel around the plastic visor and move in the room. "Over time, these droplets can disperse on a large area in the lateral and longitudinal directions, although the decreasing droplet concentration," wrote the authors of the study.

The study also revealed that the masks with ventilation holes were also insufficient to protect against the propagation of COVID, claiming that the droplets were able to pass freely through the valve and in the general space. On the other hand,Some non-surgical face masks have been able to contain aerosol droplets To travel forward, even when it is violently expelled during coughing or sneezing.

The data were collected via a visualization using a manikin head connected to a fog machine and a pump. A"laser leaf" was then used Illuminate the steam having passed through the head of the mannequin, which has been equipped with a face covering and simulated different behaviors such as breathing, talking, coughing, or sneezing, live science reported. During the face shield simulation, it has been found that, if many particles were directed towards the soil, some were able to float near the bottom of the visor before floating in the air up to three feet away of mannequin.

Other studies have welcomed the conclusions thatA type of facial coating can do more than others Stop the propagation of COVID. An article in August inNikkei Asian Review I have shown that a Japanese supercomputer known as "fugaku", spreading simulations of droplets involving different types of masks. The results showed thatStandard clear blue disposable medical masks were the most effective Contain potentially contaminated aerosols, stop almost all particles compared to 80% stopped by masks made of woven material or polyester.

These data are also in line with the guidelines of disease control and disease prevention centers (CDC), which indicate: "at that time,We do not know which level of protection A face shield provides people close to the spray of carrier's respiratory droplets ... Therefore, CDC does not currently recommend the use of face shields as a substitute for masks. "And for more information on how you can make your EPP even more efficient,If we all do this, "the pandemic will probably die," says scientist.
