Beloved, I wish above
all things that thou mayest ... be in health...
3 John 1:2
"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.
Every material tested dramatically reduced the number of droplets that were spread. But at distances of less than 6 feet, enough droplets to potentially cause illness still made it through several of the materials.
“A mask definitely helps, but if the people are very close to each other, there is still a chance of spreading or contracting the virus,” said Krishna Kota, an associate professor at New Mexico State University."
