Anyone can get a cold at any time and they are very common:

  • children can get about 5–10 colds per year
  • adults can get 2–4 colds per year
  • children get more colds than adults because they are not immune to as many cold viruses as adults are.

Colds are caused by a virus. There are about 200 different viruses that can cause a cold and each one is slightly different. That is why you can get one cold after another. Once your immune system has fought off an infection with one particular cold virus, you will be immune to that virus. The cold is also called acute viral rhinosinusitis.

Find out about the medicines and treatments for relieving the symptoms of a cold.

The common cold is not the same as flu (influenza). Flu is caused by a completely different virus (influenza virus A or B), and has much more severe symptoms. However the cold virus can still make you feel unwell and is usually more than just a runny nose.
