Epiglottitis can be fatal because an inflamed epiglottis can obstruct the laryngeal aperture and prevent air from reaching the lungs.
Epiglottitis:
A potentially fatal condition known as epiglottitis develops when the epiglottis, a little cartilage "lid" that covers your windpipe, expands and obstructs airflow to your lungs.
The epiglottis may expand due to a variety of conditions, including infections, direct injuries to the throat, and burns from hot liquids. In the past, infection with Haemophilus influenzae Type b (Hib), the same bacterium that causes pneumonia, meningitis, and infections in the bloodstream, was the most frequent cause of epiglottitis in infants. Epiglottitis can strike people of any age.
Sometimes the bacteria that cause epiglottitis also cause infections in other parts of the body, such as bloodstream infections, meningitis, or pneumonia.
