IS IT A COLD OR ALLERGIES?

It’s often hard to tell the difference between a cold and allergies. Both can cause similar symptoms, such as a runny and/or stuffy nose, sneezing, fatigue, and a sore throat. However, there are some differences that might help you tell if it’s allergies vs. a cold.

Simply put, colds are infections caused by viruses. Colds can be contagious up to two days before symptoms start and can last two weeks after exposure to the virus. Allergies, on the other hand, are not contagious, and the symptoms you experience are your immune system's reaction to allergens, such as pollen.

Take our simple allergies vs. cold quiz to learn the differences between cold and common allergy symptoms.
