Historically epiglottitis has been considered a childhood disease. However, the introduction of the Haemophilus influenzae type B vaccine has decreased the incidence of epiglottitis in children. It is important to recognize modern epiglottitis as a disease of adults. This report describes a case of acute bacterial epiglottitis in an adult patient secondary to infection caused by Streptococcus pyogenes, a group A streptococcal infection. This case demonstrates the importance of early recognition of epiglottitis in adults, as they can experience rapid clinical decline. The progression of this disease can lead to abrupt airway obstruction necessitating emergent airway management.
