Common Cold

Colds are caused by viruses in the upper respiratory tract. Many young children—especially those in child care—can get 6 to 8 colds per year. Symptoms of a cold (including runny nose, congestion, and cough) may last for up to ten days.

Green mucus in the nose does not automatically mean that antibiotics are needed; common colds never need antibiotics. However, if a sinus infection is suspected, your doctor will carefully decide whether antibiotics are the best choice based on your child's symptoms and a physical exam.
