Which term is used to describe disease-causing microorganisms that can be transmitted by droplets or airborne routes?

• A. Airborne
• B. Airborne pathogens
• C. Aspergillus
• D. Bacteria

Answer: (B)

When discussing how infections spread, we distinguish the agents from the transmission route. The term that captures the idea of disease-causing organisms that can travel through the air is “airborne pathogens.” This phrase explicitly names the agents (pathogens) and links them to their mode of spread (airborne transmission). Using just “airborne” would describe the route, not the organisms themselves, and “airborne pathogens” is the precise way to refer to those agents that can be transmitted via aerosols or small droplets. Aspergillus is an example of a specific organism that can be present in the air, but it’s just one member of the broader category, and “bacteria” is a general group that includes many organisms with various transmission routes, not specifically the airborne route. In infection control, recognizing pathogens that can be transmitted through the air informs the use of relevant precautions and facilities, such as airborne precautions and appropriate respiratory protection. Classic airborne pathogens include tuberculosis, measles, and varicella, which helps illustrate why the term is needed to describe the agents themselves.
