Title, so Citizen Smith up there doesn't get any more upset.
But they don't escalate to pre-handwashing levels. Yes, it has been suggested that the abrasive action of paper towels removes more bacteria than hot air drying (in a study funded by some tissue consortium). However, these measurements are taken immediately before and after drying - ie, once the act of pissing and hand-washing is complete. Bacterial load on the fingertips more than doubles after pissing, and washing with water and soap (for 15-20 seconds, as generally recommended - not two minutes) massively reduces this. Arguably, yes, you might get further benefits from using a paper towel - but washing and using a hot-air dryer still results in far fewer bacteria than simply not washing at all.

Either way, a minute's worth of hot air to turn your hands from damp to dry will have little or no ongoing effect on binary fission, and bacteria simply won't divide all that often in a single, solitary minute.

EDIT: That all said, I'm just cherry-picking hastily googled results to back up my initial position, and discarding those which don't fit. There's someone on here who seems very knowledgeable with this kind of stuff - far, far more so than me. Can't quite recall who, but I think it might be Mighty Badger. Perhaps he'd be kind enough to resolve it, if he's passing... Or the other Badger would suffice - I'd imagine he's professionally obliged to know how best to prevent various nasties spreading from A to B.
