Many places, knowing that one had HIV/AIDS and willingly exposing other people to the disease was/is a felony charge, in some cases, it falls under the charge of attempted murder.
This should be no less, if she knew she was in Africa (she could be that dumb, she might be a democratic aide).
If she knew she was feeling sick, and still went out instead of the hospital.
This could easily be a chargeable offense, if she survives.
An attempted murder charge count for everyone she has encountered/possibly exposed during the day at least.
