There is no evidence that a quarantine or general confinement of the foregoing classes of persons would effectively halt the spread of AIDS. Even should such a quarantine be logistically possible and achieve some benefit, its cost would make it impractical. From a moral perspective, confinement measures would constitute an intolerable restriction of personal autonomy. These arguments against quarantine, however, do not apply in the case of certain exclusionary actions against particular persons who have demonstrably harmed or wrongfully exposed others to a high degree of risk. Also, certain AIDS-infected persons might be excluded from schools or occupations when there is evidence that their presence or behavior would be directly harmful to others. Exclusion is justified to the extent it is linked with protection from demonstrable, direct, involuntarily incurred harm. 24 notes.
