is swelling of the epiglottis. The epiglottis is the flap of tissue at the back of your tongue. The epiglottis opens when you breathe and closes when you swallow so that no food goes down your airway. Epiglottitis is commonly caused by a bacteria such as Haemophilus influenzae type B (Hib). It can also happen when you breathe in steam, certain chemicals, or smoke from a fire. When the epiglottis swells, it can block your airway. This can cause problems breathing and in severe cases can block your breathing completely. This condition is a medical emergency.

Ask your healthcare provider if you need the Hib vaccine. This vaccine helps prevent Hib infection and problems such as epiglottitis. The Hib vaccine may be given to an adult who did not get the vaccine during childhood. It may also be given to an adult who has risk factors for infection. Risk factors include sickle cell disease, HIV infection, chemotherapy treatment, or a bone marrow transplant.
