What Causes a Cold?
Colds are caused by hundreds of different cold viruses. When you are infected with one of these viruses, your immune system attacks it. The cold symptoms you experience – cough, sore throat, and congestion – are effects of the immune response to the cold virus. Colds are contagious, so they can be passed from person to person, either through the air or through close contact with a person infected with the virus or a surface contaminated by the virus.1
What Causes Allergies?
Allergies are caused by an immune response to non-infectious substances, such as dust, pollen, or pet dander. Your body mistakes these substances for germs and attacks them, causing coughing, sneezing, and runny nose, the same way it does when fighting a cold. Unlike colds, allergies are not contagious, although some people may have a genetic tendency to develop allergies.
