Contagion is most commonly associated with the spread of disease, poison, corruption, harmful practices or ideas, but its Latin root — con- (together) + tangere (touch) — opens the term in a slightly different direction: co-touching, touching together. Thus: emotional contagion, behavioral contagion, financial contagion, sacred contagion, hysterical contagion, “contagion theory” (the hypnotic effects of crowds), contagion of ideas, contagion of identity.
