Both of you are wrong.
Who is the doctor? Who is the patient? Snyderman wasn't treating anyone.
If a plumber breaks quarantine and gets someone sick, that person may (or may not) have a cause for a harming the other person. Probably not in most cases, otherwise we would be inundated in lawsuits everytime someone caught an illness from another person.
Nothing changes if the person breaking quarantine is a doctor.
Medical malpractice only applies if the doctor is rendering medical services to his or her patient.

She committed an overt act in violating the quarantine.
She should pay a fine, have it placed upon her medical record, and be liable to whoever is injured by her actions.
