What is a Cold

Do you have a runny nose, cough, and nasal congestion? In such conditions, it is very difficult to differentiate between allergies and cold, as both of them involve the immune system.

What is a Cold?
Cold, cough, and congestion are actually effects of the immune system responding to these intruders.  If a cold is caused by a virus, it is contagious.  The common symptoms which accompany a cold caused by viruses are a sore throat, sneezes, cough, and stuffy or a runny nose.

If a person contracts cold suddenly and it occurs at the same time of the year, every year, it is a symptom of an allergy. 

Some of the common symptoms of allergies are itchy eyes, running, and/or stuffy nose.  Allergies can take some weeks before they are completely eliminated from the body.Differences Between Allergies and Cold

To differentiate between symptoms of allergies and cold, understand that the symptoms of cold take few days to appear after the person has been infected with the virus.  The duration of a cold can be anywhere between three to fourteen days, but allergies last till the person is exposed to the affecting allergen.  To prevent cold, make sure you are not in proximity of people who have a cold.
