Kinda? You have to keep moving or you'll start deteriorating like everything else, but you don't want to run too fast and attract attention. I tried climbing up a building at one point. Some of the things can fly, but it's a small portion of the whole mess. I had to come down and move on once my skin started peeling off in places.

That vanished when the sun came up, for the record, but I think if it killed you that wouldn't help. The wounds I got from the monsters didn't though, those stay. There's like a million types and I only ran into a few. You'd have better odds with a weapon, but it's hardly a guarantee. And I don't think anything works against all of them.
