Croup is a viral infection that usually affects children between the ages of three months to six years. It is more common in boys than girls. Croup often follows a cold, although croup may begin without cold symptoms. This illness is most often seen in the fall and winter. Croup may reoccur during childhood, but attacks tend to disappear as the child grows.
