Cold or allergy: Which is it?

If you tend to get frequent "colds" that develop suddenly and occur at the same time every year, it is possible that you are actually suffering from seasonal allergies. Although colds and allergies may share some of the same symptoms, they are very different diseases. Here's why:

• Cause. Colds are caused by viruses. Allergies are an immune system response caused by exposure to an allergen — something you're allergic to — such as pollen or pet dander. Cold viruses are easily spread from person to person. You can't "catch" an allergy from someone who has an allergy.
• Duration. Cold symptoms can develop at any time and usually last from two to 14 days. In contrast, seasonal allergy symptoms start at the same time every year and may last for months.
• Treatment. Treatment of a cold may include rest, pain relievers and over-the-counter cold remedies, such as decongestants. Treatment of seasonal allergies may include over-the-counter or prescription antihistamines, nasal steroid sprays and decongestants.
• Prevention. To help prevent colds, wash your hands frequently and thoroughly. To help prevent allergy symptoms, avoid exposure to known allergens.

The only way to truly know if you have allergies is to be tested for them in your doctor's office.
