That's true, I never did see "sick" in her profile, only that her bar was halfway down (before she got attacked by this last monkey event), so I didn't think to try to "heal" her.
Besides, even with declining health, she never stood still long enough, except in the flower field. But still, I was very suprised to see her die. And my poor villagers...they have lost their will to... PAR-TAY!! lol!
