 Medical confidentiality promotes the individual’s medical autonomy, by sheltering those seeking morally controversial medical care from outside criticism and interference with decisions (Dworkin et al. 2007; Englehardt 2000a; Feinberg 1983). Patients seeking cosmetic, abortion or fertility treatments might not wish others to know their plans. Members of the general public have from time to time attempted to influence choices strangers make relating to the care of disabled infants, comatose or brain dead kin, and abortions. Spouses, partners, parents and siblings have sought involvement, with arguably greater moral warrant. H.J. McCloskey suggested that loving personal relationships call for mutual accountability (McCloskey 1971). Of course some health problems—morbid obesity, scoliosis, psoriasis, paralysis—simply cannot be concealed from intimates. Bioethicists, consistent with public health considerations and laws, commonly argue that hidden contagious conditions or exposures should not be concealed from vulnerable associates and in extreme cases could justify non-voluntary isolation or public health quarantine (Presidential Commission 2015a).
