Prudent consideration from the viewpoint of Bioethics about the patients, the families of patints, those who engage in medical treatment and examination and terminal on the patients is required.
What the medical have to be specially careful about are:
1. Duty to medically treat patients
2.Quick information of the result of the examination to the patients
3. Obligation to keep secrets of the patients
4. Justification and duty of exceptional information to the third party who confronts the danger of infection
5.Sufficent psychological, social, institutional support system for the patients
Then, such acts as patients themselves
preserve the infection are also required on the basic rule, "Do no harm on others."
In the case4, for exmple, when a surgeon team operate on the patients who have been infected with HIV, notification of the fact to the team is justified.
In several states in America, the law allows doctors to warn the spouse of the patient, "Your spouse is infected with HIV" exceptionally if several criteria are met. Needless to say, the view that no information about the patints' health should be leaked out is also strong. Now, the trouble about patients' privacy, accessing jobs, carring insurance, and social discrimination is under discussion.
