Some evidence suggests that hospitalization for croup may be associated with future development of asthma. Children hospitalized for croup have demonstrated higher levels of bronchial hyperresponsiveness and an allergic response to skin testing. Further factors that could contribute to asthma later in life are history of recurrent croup, family history of asthma, and smoking exposure in the home environment.
