Hi!
OM First Contact precedes Voyager Endgame in the canon - in fact the only Trek film to be after the return of Voyager is Nemesis.
MY BAD! I meant Nemesis. The scene I had in my mind was Admiral Janeway talking to Picard...then I remembered she was remarking that a Reman had become the leader of the Romulan Empire...that was Nemesis, not First Contact. Thanks!
Still, the rest of what I said would be true. All Borg connected to the Collective would have been infected with the neurolytic pathogen.
