How common is epiglottitis?

Before the widespread use of Hib vaccinations in 1985, epiglottitis mainly affected children between the ages of 3 and 5. By the year 2000, the annual incidence of invasive Hib infection, a primary cause of epiglottitis, in children ages 3 to 5 decreased 99%, to less than 1 case out of every 100,000.
