Things that cause asthma symptoms, episodes or attacks are called triggers. Triggers are everywhere. Your home, workplace, or your child's school or childcare setting can be full of triggers such as viruses, pests and mold.
If you or a loved one has asthma, it's important to learn what triggers an asthma episode. You should also learn what steps you can take to reduce these triggers.
