What is defined as being transported by air?

The term that specifically describes transmission through the air is "airborne." This category includes pathogens, such as viruses and bacteria, that can be suspended in the air and transmitted to individuals through inhalation. Airborne transmission is significant in understanding how certain diseases spread, as these microorganisms can travel through the air over a distance and remain viable for varying periods.

In contrast, waterborne refers to transmission through water sources, foodborne involves the spread of pathogens via food, and surface contamination pertains to organisms residing on surfaces that people may touch. Each of these terms highlights different routes and mechanisms of transmission, but "airborne" specifically and correctly identifies the process of being transported by air.
