I still wonder about Voyager's entire medical staff being killed when the ship is pulled into the Delta Quadrant. Sickbays are usually mentioned as being in the most heavily protected part of the ship.
voyager lost a lot of peole when they got pulled into the Delta Quadrant. And it's a small ship so it wouldn't have that many medical people on board anyway. Also I would guess since they were only going on a two week mission they didn't have a ful medical staff. Probably just one doctor and one nurse.
