That's a fancy way of saying cover up when you cough! Cold and flu viruses spread via “respiratory droplets," which land on surfaces, get picked up, and eventually make their way to your eyes, nose, or mouth.
Catch your cough or sneeze with a tissue or use your elbow. But don't use your hand—that just increases the odds of spreading the virus.
And for when a virus does strike…
If you have a fever over 100.5 or other bothersome symptoms, stay home and rest, says Furuya. Coughing and sneezing are the easiest ways to share whatever’s making you sick. Plenty of rest and fluids should kick most colds and flus within a few days, but if symptoms don’t begin to improve, or they worsen, within three days, see a doctor.
