Masks Not Enough to Stop COVID19 Spread Without Distancing - استفاده از ماسک بدون فاصله گذاری برای کنترل کرونا کافی نیست

Simply wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing.

In Physics of Fluids, by AIP Publishing, researchers tested how five different types of mask materials impacted the spread of droplets that carry the coronavirus when we cough or sneeze.

Each of the masks captured the vast majority of droplets, ranging from the regular cloth mask, which allowed about 3.6% of the droplets to go through, to the N-95 mask, which statistically stopped 100% of the droplets. But at distances of less than 6 feet, even those small percentages of droplets can be enough to get someone sick, especially if a person with COVID-19 sneezes or coughs multiple times.
