Well AFAIR virii are like that - they tend to be found, well, about everywhere, provided viral load is sufficient. That doesn't mean that their protein spike has an affinity (i.e. can bind to and infect) to other cells, so "attacking the whole body" is a bit of an overstatement. It's just shit luck it targets a receptor that is prevalent in key organs, as it regulates the blood flow. Then again i am not really an expert so let's leave it at that.
