How is epiglottitis primarily transmitted?

Epiglottitis is primarily transmitted through aerosol droplets, which are released into the air when an infected person coughs or sneezes. These droplets can then be inhaled by others nearby, leading to the spread of the bacteria responsible for the infection, such as Haemophilus influenzae type b (Hib). This mode of transmission highlights the infectious nature of epiglottitis and underscores the importance of respiratory hygiene and vaccination in preventing its spread.

The other options present methods of transmission that are not typical for epiglottitis. Contact with contaminated surfaces primarily pertains to illnesses that can be spread via fomites, while consumption of contaminated food would relate more to gastrointestinal infections. Lastly, direct skin-to-skin contact is not a common route for respiratory infections like epiglottitis. Therefore, understanding that aerosol transmission is the primary mode for epiglottitis helps emphasize the need for preventive measures such as vaccination and reducing exposure in crowded or healthcare settings.
