Which of the following is NOT an example of a fomite?

Fomites are inanimate objects or surfaces that can carry infectious agents and contribute to the spread of infections. The correct choice, which is not considered a fomite, is airborne pathogens. Airborne pathogens are microorganisms that are transmitted through the air, often via droplets or aerosolized particles, making their mode of transmission distinctly different from that of fomites.

In contrast, doorknobs, utensils, and medical equipment are all examples of fomites because these surfaces can harbor pathogens that remain viable for a period, allowing them to be transferred to individuals who touch them. Understanding the distinction between fomites and airborne pathogens is crucial in infection control practices, as it informs the appropriate measures for preventing the spread of infections in various settings.
