Each person is teeming with bacteria, and we have a lot of viruses, too. A lot of the bacteria that live on and in our bodies can cause disease even if they aren't causing problems at the moment (for instance, E coli in the gut). So, no way. If each person lived in isolation for a year they'd still come out teeming with germs. But maybe it would theoretically wipe out some certain pathogen – I can't think of any, though. We actually need our bacteria, a lot of what goes on is a symbiotic relationship.
