Mass sociogenic illness--real and imaginary.
Mass sociogenic illness is the occurrence of a group of nonspecific physical symptoms for which no organic cause can be determined and is often transmitted by 'line of sight'. The fear of bioterrorism can also lead to panic and produce cases of mass sociogenic illness, in which people develop symptoms in response to an imaginary threat. Poison centers are faced with resolving the dilemma of sociogenic vs poison related symptoms. We report 2 situations of mass sociogenic illnesses involving school age children where multiple victims exhibited similar symptoms prompted by the presence or suggestion of fumes. Symptoms resolved spontaneously. When clusters of unexplained illness occur, a sociogenic etiology should be considered in the differential diagnosis. As fears about bioterrorism increase, the frequency of such incidents and the anxiety generated may increase.
