My impression has always been that viruses and bacteria simply replicate by sheer chance, based on numbers. If a virus is floating in the air, then it will be contracted by anyone who comes into contact with it in the right manner. A virus doesn't "look" for its host. It simply lingers in the air where it has been expelled from another host and if the air is saturated with enough of them, another host is likely (by chance probability) to come into contact with a virus. I have always thought it was closer to a mechanical process, things accidentally coming into contact with other things in the right manner.
It could be that a virus has some kind of "mind" or "senses" but I'm not aware that we have evidence for it. Is there some evidence that viruses have any "experience"? It seems to me that viruses don't need to have experience to do what they do any more than a rock needs to have experience in order to roll downhill from a higher elevation to a lower one on the Earth.
It is obvious bacteria and viruses are distinctly different from animals with senses and the typical brain.
However, bacteria and viruses as living things [they cannot be like rocks] have some kind of very basic proto-'sense' which evolved to the human brain at present.

Granted, they are not like rocks, they have metabolism and such. However, are the most fundamental organisms "self-aware"? For example, if a virus has awareness vis a vis having cellular metabolism or whatnot, then it seems like it would be the case that every single cell in my body should be self-aware independently of my brain. Self-awareness surely must be something that is created by a brain. Viruses especially seem like very basic organisms that merely replicate themselves in a host. My point with rocks is that the behavior of a virus seems like it may not be much more than inanimate processes (albeit relatively sophisticated ones). I wouldn't think a virus needs awareness to replicate itself. I would think it just behaves according to biological mechanisms and relies on brute numbers and chance probability to reproduce. I wouldn't think that alone would constitute any kind of awareness.
It's certainly possible that micro-organisms have awareness but it also seems possible to me that they may not. And since intentionality or qualia are knowable only in the first person, I suspect that we may never know for sure.
BTW, I've seen a lot of commotion from neuroscientists claiming to have proven various things about consciousness, but on further inspection, they usually seem to rest on speculation. There was a stir about "micro-tubulars" or something and there was a group of neuro-philosophers/scientists who speculated that they were the connection between consciousness and the brain or something like that, however, it doesn't appear that there is solid evidence of it from what I've read. I believe with Chalmers that consciousness is a potentially unknowable black box. It can't be seen or measured or anything by an outside observer.
