Jesus. You didn't even pass high school biology, did you?
The lifespan of viruses outside of living bodies is rather limited. Moreover, without cells to infect, the virus won't replicate.
By contrast, during an infection the body serves as a virus-replicating factory of sorts, copying the virus over and over again. Coughs and sneezes send droplets of mucus containing the virus flying around the room, providing a constant source of potential infections.
An infected person has a chance of transmitting the virus that is literally thousands of times higher than the chance of simply carrying the virus from an infected patient to an uninfected one.
