Is there a shared somatic disorder? Communication of non delusional symptoms in Nigeria

In a setting in which somatic symptoms without obvious organic causes are prevalent and in which doctors do not have very convincing explanations to offer, people in prolonged contact with such patients may appear to develop similar symptoms but claim the original patient as the source of their symptoms. At times, it is the original patient that detects the similarity and raises the question of contagion. Based on a study of four Nigerian patients, the author proposes the possible existence of a shared somatic disorder, comparable in many ways to induced psychotic disorder (DSM-III-R) and reopens the discussion on the whole concept of sharing/communication of psychiatric symptoms.
