And the people on the Cleveland planes, both of them, to and fro, and the people who next boarded those planes, aren't at high risk unless they touched a surface covered with that nurse's fluids. It isn't airborne.

So really only
the passengers on either side of her who likely rubbed elbows with her sweat
Her airstaff who would have served her drinks and taken her glass away (mine always wear gloves anyway in the cleanup phase, I've noticed that)
The one who had her seat after and used her tray, but not, probably, anybody after that in that seat using that tray
Anyone whom she bumped into on her way to or from either of her seats
Anyone who bumped into her getting past her seat
Anyone who bumped/was bumped by her at either of the airports or at any time since she became feverish
The people who cleaned up after her on the plane
How did she get to the airport? Public transport? Cab? ditto
The people who were with her while she was feverish at home
The people who were with her in Cincinnati, or bumped into her between the airport and her destination and back

But, not all the people on both planes, as with bird flu or something airborne.

Once she had a fever of any kind she should have known to isolate herself and the CDC should have isolated her and not okayed her travel! I can't believe the idiocy! On everybody's part! The one thing we know, they all, roundly, ignored! It's not as if we didn't know better, for crying out loud!
