I don't know enough to comment about what the SA's have done or are doing. But, I have to believe they wanted to avoid something like this:
About 82 of the 90 cases were students, with the rest being cadre.

110 tested
82 students positive
8 cadre positive
DS was 1 of the 82
Granted, the two situations are different. If an SA is "an environment conducive to the spread of the contagion", then SERE school is a Petri Dish.
I wouldn't be too quick to ascribe deliberate malfeasance to your DD's situation. The outbreak at Bragg seemed to be the result of a combination of factors: Incompetence born of inexperience and the desire/need to keep the pipeline flowing.
In any event, I hope DD's recovery continues and would recommend she limit her discussion about her recovery to the specialists and her family. Having been there and done that early on, if I didn't see some headline about long haulers, then the first question I would get for months after was, "Are suffering after effects?" It doesn't help. Every body is different and every physical or mental stress environment is different. DD's body was/is being tested by both kinds of stress.. My full recovery was very slow. It took about a year to get back to my 60+ year old declining trendline. as measured by my participation in HIIT: rest time between intervals, weight used, # of push ups, etc.
If your/her concerns are great enough, consult specialists who are not on the WP payroll.
Again, I wish her the best and peace of mind to Mom and Dad.
