Respiratory droplets are the
primary carriers of coronavirus --and we project A LOT of droplets
every time we cough or sneeze.
To be considerate and prevent the spread of coronavirus to others, capture your spray of droplets, in any manner possible: into a tissue, your sleeve or shirt, etc. (However, catching the spray with your hands is not a preferred method since you'll then be spreading your germs to everything you touch.)
By limiting the spread of respiratory droplets, you may be protecting a lot more people than you think:
those currently around
you who may breathe in your droplets.
come by minutes later to breathe the virus filled air that is still hoovering.
