Which can be stopped by covering your coughs and sneezes (with your elbow or a tissue, per CDC recommendations) and maintaining 6 ft. Again, ten rct' s over the last 70+ years all show that masks are ineffective at stopping the spread. So even if they catch large droplets, they still don't change the chance of transmitting it. What does that tell you? Large droplets are not the main vehicles for transmission. Really not that hard.

"There are simple things you can do to help keep yourself and others healthy.
Wash your hands often with soap and water for at least 20 seconds, especially after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
Avoid touching your eyes, nose, and mouth with unwashed hands.
Stay home when you are sick.
Cover your cough or sneeze with a tissue, then throw the tissue in the trash."
