    What is mold?

    • Tiny fungi that live in damp, dark, warm environments.
    • Their “seeds,” called spores, travel through the air.  
    • Mold can be found indoors and outdoors.  
    • There are hundreds of types of molds, but not all of them are responsible for causing symptoms.  
     
     

    What is a mold allergy?

    • Everyone breathes in mold spores in the air, but some people can have an allergic reaction or asthma symptoms if exposed to too much of this fungus.
    • If you are allergic to mold, your immune system is sensitive to specific mold spores causing your body to have a reaction. 
     
     

    What are the symptoms?

    • When the spores get into your child’s nose, they can cause symptoms of allergic rhinitis or “hayfever”. These symptoms can include:
      • Itchy nose, mouth, or lips.
      • Sneezing.
      • Itchy, watery eyes.  
      • Stuffy or runny nose.
      • Mucous in the throat, post-nasal drip.
      • Coughing.

    • Asthma symptoms:
      • Coughing.
      • Wheezing.
      • Shortness of breath or trouble breathing.
      • Chest tightness.  
     
     

    How are mold allergies diagnosed?

    • Your child’s healthcare provider will ask you questions about your child’s symptoms and exposures and perform a physical exam.  
    • Your child might be referred to a physician specializing in allergies who might do additional testing such as skin and/or blood tests.  
    • There is no special test to look for mold in your body. There are no special remedies or methods to “detox” from mold. Be wary of mold misinformation. 
     
     

    How can I prevent symptoms from mold allergies?

    If your child is allergic to mold, the best thing you can do is try to avoid exposure to mold.

    • Outdoors
      • Stay indoors on days when mold counts are high. Visit pollen.aaaai.org to monitor mold counts near you!
      • Take a shower after coming indoors or before bed. This will wash out mold spores in your hair to keep them from bothering you all night long.
    • Indoors
      • Fixing leaking plumbing and roof leaks.
      • Reduce the humidity in your home. Be sure your indoor humidity stays below 60 percent.
      • If you use a humidifier, clean the fluid container at least twice a week to prevent mold growth.
      • Use an exhaust fan or open a window during baths, showers, while cooking, and while washing dishes. Keep the fan on for 15-20minutes afterwards too.  
      • Increase air flow in your home. Open doors between rooms, move furniture away from walls, and use fans if needed.
      • If mold grows, clean it right away. You can clean mold off walls using a vinegar solution.

    How is this treated?

    • Your child’s healthcare provider might recommend oral medications, nose sprays, or eye drops.
    • Some children receive immunotherapy (also known as allergy shots) with their allergy specialist. 
     
     

    When to call your doctor:

    • Your child is having fever.
    • Your child is having difficulty breathing.  
    • Your child is getting worse.
    • You have other questions or concerns.
