Cold, Flu or Allergy, What's the Difference?

A virus is a microscopic living that gets into your body and makes you feel chilly. The immune system, your body's defense against viruses, fights back when you have a cold virus. As your immune system fights off the illness, your symptoms should disappear in little more than a few weeks. When it comes to allergies, things are different. This response causes the classic symptoms, such as a stuffy nose or cough. Viruses that cause colds can spread quickly. You can contract the infection from an infected person if they cough, sneeze, or shake hands with you. This might cause your nasal passages to swell, which can lead to coughing and sneezing.
