Coughs and colds in children.

Most coughs and colds are caused by germs called viruses. Many different viruses can infect the nose and throat. They are passed on by coughing and sneezing the virus into the air. An average preschool and primary school child has 3-8 coughs or colds per year. Sometimes several coughs or colds occur one after the other. A child who lives with smokers has an increased risk of developing coughs and colds.
