What is croup?

    Croup is an infection that causes the throat and upper airways of the lungs to swell and narrow. It is also called laryngotracheobronchitis. Croup makes it harder for your child to breathe. This infection is common in children 5 years or younger, but your child can get croup at any age. Your child may get croup more than one time. 


    What increases my child's risk for croup? 

    Croup is commonly caused by a virus. The virus is spread through the air when others cough or sneeze. It can be spread if your child touches contaminated items and then touches his or her mouth, nose, or eyes.


    What are the signs and symptoms of croup?

    Croup may start like a cold with a stuffy or runny nose and fever. As your child's airway becomes swollen, he or she may have any of the following:

           Barking cough that is worse at night

           Noisy, fast, or difficult breathing 

           Hoarse or raspy voice 

    How is croup treated? 

       Moist air may help your child breathe easier. If your child has symptoms of croup, take him or her into the bathroom. Close the bathroom door, and turn on a hot shower. Do not put your child into the shower. Sit with your child in the warm, moist air for 15 to 20 minutes. Use a cool mist humidifier in your child's room. If it is cool outside, take your clothed child outside in the cool, moist air for 5 minutes. This may also make it easier for your child to breathe and help decrease his or her cough

       Medicine may be needed to help with your child's cough. Ask your child's healthcare provider what medicine to give your child for a cough. Most cough medicines cannot be given to children under 2 years of age. Your child may also need medicine for fever. Do not give aspirin to children under 18 years of age: Your child could develop Reye syndrome if he takes aspirin. Reye syndrome can cause life-threatening brain and liver damage. Check your child's medicine labels for aspirin, salicylates, or oil of wintergreen

    How can I prevent the spread of croup? 

        Wash your hands often. Use soap and water. Wash your hands after you use the bathroom, change a child's diapers, or sneeze. Wash your hands before you prepare or eat food

        Do not let your child share cups, forks, spoons, or plates with others

        Keep your child home from school or daycare

    Call 120 if: 

        Your child stops breathing or breathing becomes difficult

        Your child faints

        Your child's lips or fingernails turn blue, gray, or white

        The skin between your child's ribs or around his or her neck goes in with every breath

        Your child is dizzy or sleeping more than what is normal for him or her 

        Your child drools or has trouble swallowing his or her saliva

    When should I seek immediate care? 

        Your child has no tears when he or she cries

        The soft spot on the top of your baby's head is sunken in

        Your child has wrinkled skin, cracked lips, or a dry mouth

        Your child urinates less than what is normal for him or her

    When should I contact my child's healthcare provider? 

        Your child has a fever

        Your child does not get better after sitting in a steamy bathroom for 10 to 15 minutes

        Your child's cough does not go away

        You have questions or concerns about your child's condition or care


    You have the right to help plan your child's care. Learn about your child's health condition and how it may be treated. Discuss treatment options with your child's caregivers to decide what care you want for your child.
