It is likely that the parents spread among themselves the notion of toxic exposure at the school. A questionnaire revealed no spatial clustering, but increased reports of symptoms were related to intense media coverage. A thorough environmental and epidemiological investigation was negative, there being no evidence of a continuing gas leak or other potential causes. At a strictly biological level, the complaints in this reported \u2018cluster\u2019 apparently represented the sporadic occurrence of common childhood illnesses. The possibility of an epidemic from toxic exposure at the school caused intense parental concern and led to a major public health problem. The established term \u2018mass sociogenic illness' seems inapplicable here because complaints did not come principally from the students and the apparent epidemic illness was not transmitted among them. The term \u2018mass sociogenic illness by proxy\u2019 is proposed to describe this incident, in which transmission in one group (the parents) resulted in reports of an epidemic in another group (students).\u201d<\/jats:p>","DOI":"10.1192\/bjp.157.3.421","type":"journal-article","created":{"date-parts":[[2008,8,13]],"date-time":"2008-08-13T00:13:05Z","timestamp":1218586385000},"page":"421-424","source":"Crossref","is-referenced-by-count":9,"title":["Mass Sociogenic Illness by Proxy: Parentally Reported Epidemic in an Elementary School"],"prefix":"10.1192","volume":"157","author":[{"given":"Simon","family":"Wessely","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher J.","family":"Wardle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"170","published-online":{"date-parts":[[2018,1,2]]},"reference":[{"key":"S0007125000063169_ref12","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.284.6320.961"},{"key":"S0007125000063169_ref6","doi-asserted-by":"publisher","DOI":"10.1080\/00029157.1988.10402749"},{"key":"S0007125000063169_ref19","unstructured":"Sirois F.
