Yes yes to all this and here's the thing

> if there's even the slightest suspicion that someone has been bitten, scratched etc

With Bats, always considered you've been bitten. Especially in situations like "woke up with a bat in the bedroom" - unless you can confirm the type of bat, take this as yes, it's hospital time

As noticed by the article, bat bites can be pretty painless

Yes maybe though I've read not as much as you think, unless it happens while you were sleeping or drunk.

Besides, even if it is, you will still notice a bad on you, because they have enough weight. You notice a small bug- you'll notice an animal that might weigh as much as a mouse or rat.
