Outlook

A person with epiglottitis can recover very well with a good prognosis if the condition is caught early and treated in time. In fact, a good majority of people with epiglottitis do well and recover without problems. But if the person was not brought to the hospital early and was not appropriately diagnosed and treated, the prognosis may range from poor with prolonged physical handicap to death.

• Before 1973, 32% of adults with epiglottitis died from the disease. With current vaccination programs along with earlier recognition and treatment, the overall death rate from epiglottitis is estimated to be less than 7%. The death rate from epiglottitis in adults is higher than that of children because the condition can be misdiagnosed. Other likely diseases look so much like epiglottitis.
  
  
• Epiglottitis can also occur with other infections in adults, such as pneumonia. Most commonly, it is misdiagnosed as a strep throat. However, if it is suspected and treated appropriately, full recovery can be anticipated. Most of the deaths come from failure to diagnose it in a timely fashion and obstruction of the airway. As with any serious infection, bacteria may enter the blood, a condition called bacteremia, which may result in infections in other systems and sepsis (severe infection with shock, and often respiratory failure).
