Fortunately, social distancing and wearing masks works. This only makes sense: the virus doesn’t have legs or wings. It is a hitchhiker, riding along in our bodies, jumping to other bodies through droplets from our mouths or through the touch of a hand. Keep people apart, and viral spread slows down. Slow down the spread, and we buy more time to study the virus, develop treatments, resupply protective equipment and keep more people alive.
