Complications

These conditions can occur along with a common cold:

• Acute ear infection (otitis media). This is the most common complication of the common cold. Ear infections occur when bacteria or viruses enter the space behind the eardrum.
• Wheezing. A cold can trigger wheezing, even if your child doesn't have asthma. If your child does have asthma, a cold can make it worse.
• Acute sinusitis. A common cold that doesn't resolve may lead to an infection within the sinuses (sinusitis).
• Other infections. A common cold can lead to other infections, including pneumonia, bronchiolitis and croup. Such infections need to be treated by a doctor.
