Throughout the coronavirus pandemic, you may have asked, "Why do I have tocarry a face mask? "What is the effectiveness really? Or "How many people need to wear masks to stop coronavirus to spread? And as the American teters on the point of reopening, these questions become more and more pressing. Now, newIn-depth research on masks led by the computer scientistKai, PhD, has the answers.

KAI-who has joint appointments at the International Institute of Computer Science at the University of Berkeley and the Hong Kong University Forecast Model of Science and Technology builds a sophisticated system calledmasksim simulator. The model shows how the differentFace Mask Policies Work, Which represents for chance, small accidents, the efficiency of the facial mask and other variables. (You can see the simulator in action viaA video demonstration, and evenaccessmasksim in line to use the model for yourself research.)

According to Kai's research, if 80 percent of aclosed population wore masks, Covid-19 infection rates would fall to about one twelfth in the number of infections, compared to a population in whichno one wore masks.

The part concerning? Even whenNearly half of a closed population carries masks, The benefits are non-existent next door. "If you come down at 30 or 40 percent," Kai saidVanity fair, "You get almost no [beneficial] effect at all. »

So where is the American stand in terms of Kai target rates? Unfortunately, well below this threshold of 80 percent. As a country, about49 percent of the population carries masks, According to the April data of Yugov. This makes us 15 of the 26 World Markets analyzed-Behind places like Hong Kong (90 percent), China (89 percent), Italy (85 percent), India (84 percent), Japan ( 76 percent), and Saudi Arabia (59 percent), among others.

On the basis of Kai's search, we know that 49 percent of the American populationput on masks Everything will not cut when it comes to eliminating coronavirus. However, there are signs of hope that indicate that we can arrive at this soft spot 80-90 percent. After the Centers for Disease Control and Prevention (CDC) officially recommended theUsing masks In public places on April 3 a Gallup survey conducted from April 7 to April 14 revealed that62 percent of Americans reported wearing a mask Outside their house, compared to 38 percent before the week. We just need to continue on a similar trajectory to ensure you stay safe now that Lockdowns are starting to raise.

As a Kai collaboratorGuy-Philippe Goldstein, An economist expert and cybersecurity, saidVanity fair: "What is most important to wear masks is right now that it works, as well as social distancing, to flatten the curve of infections that we expect treatments and vaccines to develop, while allowing people to go out and some companies to reopen. "And for the correct manipulation of your mask, see7 face care mask errors you make.
