Recent consideration of applying the duty to warn has raised questions regarding therapists' responsibility to breach confidentiality in order to report clients' nonviolent behaviors which may pose danger to others, as in the case of clients with HIV/AIDS. Clients with HIV/AIDS who are sexually promiscuous or share needles may pose risks to their companions, who may be unaware of the client's health condition. Although the possibility of infection that may result is a factor of concern, the duty to warn currently does not prescribe breaking confidentiality in these cases. In such cases, there may be uncertainty regarding potential victims and, perhaps, ignorance about the occurrence of behaviors that would pose the danger of transmission. Furthermore, many states prohibit the disclosure of information about HIV/AIDS.
