Psychic infection occupies a distinctive position in the depth-psychology corpus as both a clinical metaphor and a socio-cultural diagnostic. Jung introduced the term with deliberate epidemiological force: the therapist, like any organism exposed to pathogenic material, does not remain untouched by the patient's psychological disorder. In Sedgwick's careful unpacking, this metaphor shifts registers—from medical contagion toward a more fully psychological account of mutual vulnerability, emotional hurt, and the porous boundary between healer and sufferer. At the clinical level, psychic infection names what happens in the consulting room when the analyst's own unconscious is mobilized by contact with pathology; it underlies the Jungian insistence on the analyst's personal analysis as prophylactic and as preparation. At the collective level, Jung deploys a cognate concept—the psychic epidemic—to account for political possession, mass irrationality, and the spread of ideological fanaticism when rational checks fail and the threshold of affect is breached. The index entry in Civilization in Transition explicitly equates 'infection: psychic' with 'epidemic, psychic,' confirming the terminological continuity. Sedgwick, the primary commentator represented here, traces the metaphor's limits with precision, noting that no literal microbes are involved and that the concept most productively serves as a bridge to notions of countertransference and the wounded healer. The concept thus stands at the intersection of clinical technique, analytical ethics, and cultural pathology.
A central Jungian metaphor for the therapeutic relationship that is closer to home, and to medicine, than the previously mentioned ones of alchemy or childhood is psychotherapy as psychic infection.
Sedgwick identifies psychic infection as Jung's primary medical metaphor for the therapeutic relationship, in which the therapist is understood to be psychologically contaminated by the patient's maladjustment.

the Jungian metaphor begins to shift from physical infection—as in a healthy victim getting infected by the sickening disease—to something to do with equality and human emotional vulnerability.
Sedgwick argues that Jung's infection metaphor ultimately transcends its biomedical origins, becoming an account of shared emotional vulnerability and the analyst's own woundedness as the ground of therapeutic power.

moral and mental remedies would be more effective because they could provide us with a psychic immunity to the ever-increasing infection. But all our attempts have proved to be singularly ineffectual
Jung transposes psychic infection to the collective-political register, arguing that shadow recognition is the only reliable immunity against the ideological contagion spreading across Cold War civilizations.

dangerous as sources of infection precisely because the so-called normal person possesses only a limited degree of self-knowledge.
Jung identifies latent psychotic personalities as vectors of collective psychic infection, arguing that limited self-knowledge in the general population creates the fertile soil for their chimerical ideas to spread.

a sort of collective possession results which rapidly develops into a psychic epidemic. Under these conditions all those elements whose existence is merely tolerated as asocial under the rule of reason come to the top.
Jung describes the mechanism by which collective psychic infection escalates into a full epidemic once affective temperature breaches the threshold of rational containment, releasing previously suppressed asocial forces.

If ever there was a mental epidemic it is the actual mental condition in Germany. Hitler himself (from what I heard) is more than half crazy.
In private correspondence Jung applies the epidemic model of psychic infection directly to National Socialism, treating Hitler's Germany as the paradigmatic case of a mass psychic contagion.

the doctor must change himself if he is to be capable of changing his patient and keep on changing in order to do the work.
Sedgwick frames the analyst's required self-transformation as the practical consequence of psychic infection: genuine exposure to the patient's psychology demands ongoing change in the therapist.

Demonism is a primordial psychic phenomenon and frequently occurs under primitive conditions... Demonism can also be epidemic.
Jung's discussion of epidemic demonism in CW 18 provides an archaic parallel to the concept of psychic infection, situating collective possession within the same structural framework as mass psychological contagion.

On account of its deep-seated roots, this identity is broken only very slowly. On the level of the unconscious, child and parent seem to have no dividing wall.
Harding's account of unconscious identification between mother and child illustrates the permeable psychic boundary through which infection-like transmission of emotional states occurs outside the clinical setting.

The theory of attenuated infection says that an infectious agent is necessary for disease in the host, but it is not sufficient for disease to break out.
Hillman invokes the biomedical theory of attenuated infection to argue that psychological variables determine whether pathology actually manifests, implicitly paralleling the host-susceptibility model with depth-psychological accounts of predisposition.
