You try to play it safe. You wash your hands for 20 seconds. You don't chew gum you find stuck under a table. You don't eat food of the floor. You spray down the gym equipment before/after you use it.
and then, while you are sitting in your car minding your own business, enjoying the breeze from your open windows....BAM! A gust from a passing train kicks up a very old and dirty burger wrapper and used napkin that slaps you right across the face. eww.
