Epiglottitis is inflammation of the leaf-shaped lid of tissue (epiglottis) that is located over the opening to the large breathing tube leading to the lungs (trachea). This flap of tissue closes when a person swallows to prevent food and fluids from getting into the trachea.
Epiglottitis can be life-threatening because the inflamed and swollen epiglottis can rapidly block the trachea and make breathing difficult. Epiglottitis generally begins suddenly, without a previous upper respiratory infection.
