Prevention
By Mayo Clinic staffTo prevent croup, take the same steps you use to prevent colds and flu. Frequent hand washing is most important. Also keep your child away from anyone who's sick, and encourage your child to cough or sneeze into his or her elbow.
To stave off more-serious infections, keep your child's immunizations current. The diphtheria, Haemophilus influenzae type b (Hib) and measles vaccines offer protection from some of the rarest — but most dangerous — forms of upper airway infection.
