Cold vs. Allergy in Children: How to Tell the Difference

Colds are infections of the upper respiratory tract (sinuses, nasal passages, throat, and larynx). They are caused by several different viruses. They are spread by:  

  • Touching a person with a cold

  • Touching an object that someone with a cold has touched

  • Breathing the virus in the air after someone with a cold has coughed or sneezed into the air

Seasonal allergies (hay fever) are caused by the immune system reacting to pollen from trees, grasses, and weeds as if it were harmful to the body. This reaction causes symptoms that can seem like a cold. Allergies often run in families. Seasonal allergies occur at the same time each year. If your child has allergy symptoms all year, they may be allergic to things (allergens) in the home. These can include dust mites, animals, mold, and cockroaches.

The table below is a guide to symptoms. See your child's healthcare provider for a diagnosis.
