The common cold is a mild viral infection of the nose and throat caused by a virus. It’s the most common infectious disease in humans, and there’s no cure. However, there are many things you can do to avoid getting the common cold, or to reduce its severity if you do get it.
The common cold is spread through contact with an infected person’s respiratory droplets, which are released when they cough, sneeze, or talk. You can also get the common cold by touching something that an infected person has touched, and then touching your face.
