Q: It seems like my daughter, who is 6, has had sneezes and a runny nose all spring. How can I tell is she has allergies or just a cold?
A: Sneezing and runny nose, as well as other symptoms of seasonal allergies such as eye irritation and cough, can also be caused by viral infections. At the beginning of a viral infection, however, a child usually seems somewhat ill -- she may have a fever, a poor appetite and less energy than usual. Symptoms of a viral infection would not last "all spring" unless the child had several different infections in a row.
By contrast, allergic symptoms last as long as the child is around the offending material, called the allergen. Pollen, grass and trees can all be allergens. A child with allergies often rubs her eyes and nose and complains they itch. The lining of her nose gets pale and puffy. She may breathe through her mouth,because her nose is always blocked.
