How does the spread of an airborne pathogen compare to the spread of foodborne and person to person pathogens?

An airborne pathogen would be much more dangerous than that of a foodborne and person to person. Why? Because there is a higher risk of contracting it. With person to person, you could avoid infected people all-together, but with airborne, it's more complex than that. Obviously, the molecular make-up is different as-well, but this is in regard to which pathogens you are talking about.
