Colds and flu tend to be more frequent in preschool age children since their immunity to these viruses is still developing. Cold and flu symptoms are the result of the body s response to the virus.

The respiratory tract tissues also become red and swollen as a result of increased blood flow to the area bringing white blood cells to fight the virus.
