| Definition: |
An upper respiratory tract disease which involves inflammation of the epiglottis due to infection. Haemophilus influenzae type B is the most common bacterial causative agent, although some cases are attributable to Streptococcus pneumoniae or Streptococcus pyogenes. The infection can cause the epiglottis to either obstruct or completely close off the windpipe. Epiglottitis typically affects children, and is associated with fever, difficulty in swallowing, drooling, hoarseness of voice, and stridor. |
