The Common cold is a viral infection that occurs in the nose, throat, and upper respiratory tract. Though it creates chaos throughout the day, It’s usually harmless. Many types of viruses can cause a common cold.
A chronic cold is a cough that lasts eight weeks or longer in adults, or four weeks in children. Coughing is a routine bodily function, but when it lasts for an extended time, it can get in the way of everyday life and be worrying. A chronic cough can be wet and produce phlegm or dry and tickle the throat.
