From gnu's link:
"Rabies in bats is very uncommon however the few cases of rabies reported in the Atlantic provinces are mostly attributed to bats. In 1989 one case of rabies in a fox on the south coast of Newfoundland was thought to be due to contact with a rabid bat. This does not suggest that people should be afraid of bats but rather they should treat bats with respect and caution. Any bat or other wild animal found under unusual circumstances (brought in by the cat, or seeming to be sick i.e. flapping around on the ground during the daytime) should be reported to local wildlife officers. If the bat must be handled do so with gloves and place in a protective container.

"Occasionally a bat, usually young and inexperienced, enters through a window. Leaving doors and windows open will allow it to escape."

The brown bat is the only one we have in Alaska. S'pity, though. We have enough flying varmints to keep 'em fat and healthy.
