Supraglottitis

Epiglottitis is a life-threatening disease. The epiglottis is the piece of cartilage at the back of the tongue that closes off the windpipe when swallowing. Without an epiglottis, food could enter the airways, and you would cough or choke after swallowing. Epiglottitis causes swelling of the epiglottis. Breathing problems increases rapidly as the epiglottis swells. Epiglottitis can get rapidly worse.

Inflammation of the epiglottis is usually caused by the bacteria Haemophilus influenzae (H. influenzae), although it may be caused by other bacteria or viruses. Upper respiratory infections can lead to epiglottitis. Medicines or diseases that weaken the immune system can make adults more prone to epiglottitis.

Epiglottitis is most common in children between 2 and 6 years old. Rarely, epiglottitis can occur in adults, and it may be easily overlooked in such patients.

The occurrence of epiglotti has decreased steadily in the United States since the H. influenzae type B (Hib) vaccine became a routine childhood immunization in the late 1980s.
