• Acute ear infection (otitis media). Ear infection occurs when bacteria or viruses infiltrate the space behind the eardrum. It's a frequent complication of common colds in children. Typical signs and symptoms include earaches and, in some cases, a green or yellow discharge from the nose or the return of a fever following a common cold. Children who are too young to verbalize their distress may simply cry or sleep restlessly. Ear pulling is not a reliable sign.
  • Wheezing. A cold can trigger wheezing in children with asthma.
  • Sinusitis. In adults or children, a common cold that doesn't resolve may lead to sinusitis — inflammation and infection of the sinuses.
  • Other secondary infections. These include strep throat (streptococcal pharyngitis), pneumonia, and croup or bronchiolitis in children. These infections need to be treated by a doctor.
