Other names for the cold are upper respiratory tract infection, URI, nasopharyngitis, and viral rhinosinusitis. This problem is referred to as a common cold for a reason — your child will probably have more colds than any other type of illness. Most kids have had eight to ten colds by their second birthdays. Furthermore, they continue throughout childhood, and their parents can only separate them from other children while the illness runs its course. This is also the most common reason that children miss school and parents miss work. If anything, using the term “common cold” is an understatement according to this explanation.
We all know our body has a relatively small number of symptoms with which to respond to an ever-changing, wide variety of viruses. These symptoms are often the body’s attempt to get rid of the virus and to minimize the damage that viruses make. Sneezing ejects the virus from the nose, coughing from the lungs and throat, vomiting from the stomach, and diarrhea ejects viruses from the intestines. Fever makes it difficult for the virus to reproduce, and those are all ways our body fights. The common cold is our name for a specific constellation of symptoms, a pattern of illness caused by a variety of different viruses. Over two hundred different types of viruses can cause the cold that people experience, and Rhinoviruses (nose viruses), are the most common. Respiratory syncytial virus, adenovirus, enterovirus, and a host of others can also produce colds in humans. Most people are sick with each specific strain of cold virus only once during their lifetime. 
Who Gets the Common Cold?
Colds are the most prevalent infectious disease, and children average 3 to 8 colds per year. In fact, younger children and boys are on the higher end of the range. Children are the major reservoir of the many cold viruses, and they usually get colds from other children. When a new strain is introduced into a school or daycare, it quickly travels through the class, infecting children.
Parents get about half as many colds as their children do, and mothers tend to get at least one more cold per year than dads. Colds can occur year-round, but they occur mostly in the winter. It happens even in areas with mild winters. In areas where there is no winter, colds are most common during the rainy season.
