There is more to modern health than new scientific discoveries, the de
velopment of new technologies, or emerging or re-emerging diseases. Wo
rld events and experiences, such as the AIDS epidemic and the humanita
rian emergencies in Bosnia and Rwanda, have made this evident by creat
ing new relationships among medicine, public health, ethics, and human
rights. Each domain has seeped into the other, making allies of publi
c health and human rights, pressing the need for an ethics of public h
ealth, and revealing the rights-related responsibilities of physicians
and other health care workers.
