The primary cause of epiglottitis is indeed linked to the Haemophilus influenzae type b (Hib) bacteria. This organism is known for causing severe respiratory infections in children, particularly in unvaccinated populations. The Hib vaccine has significantly reduced the incidence of epiglottitis caused by this bacteria, but it remains the most common cause in unvaccinated individuals.

Epiglottitis occurs when the epiglottis, the flap that covers the trachea during swallowing, becomes swollen, leading to potential airway obstruction. This condition can escalate quickly and requires prompt medical attention.

In contrast, while viral infections can cause similar respiratory problems, they are not the primary cause of epiglottitis. Other types of bacteria, like Streptococcus and Staphylococcus, can contribute to various infections but do not typically lead to epiglottitis as commonly as H. influenzae does. Understanding these distinctions is crucial for recognizing the urgency and appropriateness of treatment in suspected cases of epiglottitis.
