How is it contagious? What not to do?
RSV can spread when an infected person coughs or sneezes. You can get infected if you get droplets from the cough or sneeze in your eyes, nose, or mouth, or if you touch a surface that has the virus on it, like a doorknob, and then touch your face before washing your hands. Additionally, it can spread through direct contact with the virus, like kissing the face of a child with RSV.
Usually 3-8 days.
