Epiglottitis prevention is largely achieved by which measure?

• A. Antibiotics during viral infections
• B. Isolation precautions
• C. Prompt treatment of Hib infections
• D. Standard immunizations

Answer: (D)

The main idea here is that preventing epiglottitis hinges on preventing Hib infections. Epiglottitis in children used to be largely caused by Haemophilus influenzae type b, and the introduction of the Hib vaccine, given as part of routine immunizations, has dramatically reduced cases. The vaccine works by training the immune system to recognize Hib so invasive disease like epiglottitis is much less likely to develop. So, standard immunizations effectively prevent the disease rather than treating it after it occurs or reducing spread after it has begun.

Antibiotics during viral infections don’t prevent Hib epiglottitis, since that disease is bacterial and prevention is achieved by vaccination, not by treating viral illnesses. Isolation precautions help control spread in settings but aren’t the primary method to prevent epiglottitis in the general population. Prompt treatment of Hib infections is important after infection occurs, but it doesn’t prevent epiglottitis from developing in unvaccinated individuals.
