A cold is an infection of the nose and upper airways caused by a germ (virus). They are extremely common. An adult can expect 2-4 colds a year, and a young child about 3-8 colds a year. Many different viruses can cause a cold. This is why colds come back (recur), and immunisation against colds is not possible. Infections of the throat (larynx), or the main airway (trachea), or the airways going into the lungs (bronchi) are also common.
