I remember a listening to a podcast interviewing a physician from a major hospital who made sure to explain the difference between an airborne pathogen and one that is respiratory active.

Jogging my memory. Airborne meaning a virus that a person exhales in an elevator (example) will still be present and transmissible x amount of time later. Respiratory active meaning transmissible by coughing/exhaling in the presence of someone else.

These are important distinctions if true and still relevant.
