Sexually transmitted diseases: reflections on metaphors and ethics.

Sexually transmitted diseases (STDs) are probably the most tabooed diseases we know. The taboos and the related stigmata shape patients reality and influence significantly health care policies, medical research, and actual problems in medical ethics. To better understand these complex influences of ancient but still powerful taboos, related metaphors associated with illness and disease are analyzed according to their historical development and actual impact on society. It becomes obvious that research and health care policies cannot be satisfyingly successful in helping people affected by STDs as long as they do not take the mechanisms of taboos and associated metaphors into account.
