How can you tell difference between a cold and allergies?


Rate This Answer

Allergies Colds are caused by hundreds of viruses. When one of these viruses gets into your body, your immune system attacks. Some of the effects of this immune response are the classic symptoms of a cold, such as congestion and coughing. Allergies are caused by an overactive immune system. For some reason, your body mistakes harmless substances such as mold or pollen as germs.
