This visual sign is important because it signifies significant inflammation that can obstruct the airway, making epiglottitis a medical emergency.

Epiglottitis is generally caused by bacterial infections, with Haemophilus influenzae type b (Hib) being a common culprit, especially in unvaccinated children. The redness and swelling of the epiglottis can also lead to symptoms such as difficulty swallowing, stridor, and drooling due to the patient's inability to maintain a safe airway.

Pharyngitis often leads to generalized redness and swelling of the throat tissues, aphthous ulcers involve ulcerations rather than swelling, and strep throat is primarily characterized by redness and exudative spots on the tonsils, but not specifically
