When you cough or sneeze the germs can go very far. Large droplets fall in a few feet but clouds of very tiny droplets float in the air and can float across the room or far enough to become sucked into the ventilation system and distributed to all parts of the house.
A simple sneeze spray an average of 40,000 droplets of saliva and mucous but some sneezes can go up to about 60,000 to 120,000 droplets. It lingers around in the air for about 12 hours and you also might smell your own sneeze. The air from a sneeze can travel 10 ft away but the wet spray travels and infects people 5 ft away. Simple sneeze: Achoo!= 40,000 droplets Wet sneeze: Ha-Isshhoo!= 60,000 to 120,000 droplets happy sneezing

As far as general price goes it will depend on how far one will travel, the amount of luggage or weight of luggage, and how many passengers will travel to name a few examples.
