A transporter trace might not have existed to begin with, and depending on how the disease acted, any old traces might have been lost.
For example, if she had an illness that only started presenting itself long after she caught it, like Tholian shingles. There may no longer be a healthy trace to pull from, or the disease caused damage that a backup cannot sufficiently repair.
We do know that some health conditions generally preclude transport. It’s not very healthy for foetuses to be transported. Voyager did it, and the baby had to spend several days in ICU to make sure that being transported didn’t mangle their neurochemistry, which would suggest that’s also something a transporter cannot readily fix.
Not always they use the healthy backup. Check out dr. M’Benga’s daughter.

As previously stated, I’m leaving NuTrek out of this discussion entirely as NuTrek doesn’t care about continuity in the slightest.
