Epiglottitis

Nature 
Epiglottitis is a life-threatening disease. The supraglottic structures become inflamed and swollen, leading to narrowed airway and respiratory compromise. Epiglottitis in children almost always is caused by the bacterium [Haemophilus influenzae] type b (HIB). In adults, it frequently is nonbacterial.
