Causes of a common cold


There are over 200 viruses known to cause colds. This means that as soon as you recover from a cold, another cold can hit you by another virus. These known viruses are grouped into two, Rhinoviruses and Coronaviruses. Each group of viruses causes different types of colds with slightly different conditions.

The viruses that cause a cold attack the lining of the nose and throat, inflaming these areas. As they become inflamed, they begin to produce more mucus, resulting in a runny nose and sneezing.
