Colds vs. Allergies
Colds and allergies can cause similar symptoms in children, but colds are viral infections that usually resolve within 3–14 days, while allergies are immune reactions to triggers like pollen, dust, or pet dander and often last for weeks or longer.
Fever, body aches, thick nasal mucus, and low energy are more typical of a cold, whereas itchy, watery eyes, frequent sneezing, and thin, clear nasal drainage point toward allergies.
Sneezing tends to be occasional with colds but occurs in rapid bursts with allergies, and itching is a key sign of an allergic response caused by histamine release.
Because colds are contagious but allergies are not, recognizing these differences helps parents choose the right treatment and know when to consult a pediatrician.
