Within the depth-psychology corpus, ‘infection’ operates on at least three distinct registers, and the tension among them is generative rather than merely terminological. At the most literal level, infection appears as a medical fact — the presence of a pathogen in the body — whose causal sufficiency is, however, repeatedly called into question: Hillman, Sardello, and the traditions they invoke insist that an infectious agent is necessary but never sufficient for disease to break out, demanding that questions of meaning, host, and psychic occasion supplement the microbiological account. At a second, properly psychological register, Jung and those in his lineage — Sedgwick most systematically — deploy infection as a central metaphor for what transpires between therapist and patient: the therapist is ‘contaminated’ by the patient’s maladjustment, and this mutual psychic exposure is not an accident to be avoided but the very mechanism of healing. Here infection slides from pathology into the vocabulary of the wounded healer, and its moral valence inverts. A third register is socio-political: Jung’s writings on the mass psyche invoke ‘moral and mental infection’ as the spreading contagion of unconscious collective shadow, to which only genuine self-knowledge offers immunity. Across all three registers the corpus insists that infection is never merely biological; it is always also a question of psychic openness, resistance, and meaning.
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 argues that collective moral blindness renders Western consciousness susceptible to ideological infection, and that only confronting one’s own shadow can confer genuine psychic immunity.

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. Jung suggests that the therapist is contaminated by the patient, psychologically infected.
Sedgwick identifies psychic infection as Jung’s core metaphor for the therapeutic encounter, in which the therapist’s exposure to the patient’s maladjustment is understood as an unavoidable and structurally necessary process.

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. Perhaps infection and vulnerability are the same thing
Sedgwick traces the conceptual migration of ‘infection’ from a medical image of contagion to a fully psychological one of mutual emotional vulnerability, marking the point at which the metaphor becomes literalised as shared human woundedness.

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. The germs may be present but the disease not.
Hillman invokes the theory of attenuated infection to argue that biological causation is incomplete and that psychological meaning — what the disease serves in the patient’s life — is required to explain why illness occurs.
, Suicide and the Soul, 1964thesis
It is as if the patient’s pathology demands the mutual stuckness (infection, woundedness) in order to be fully grounded and then healed in the here and now.
Sedgwick presents mutual therapeutic ‘stuckness’ — glossed as infection and woundedness — as an indispensable, even demanded condition for genuine healing rather than an obstacle to it.

germs do not infect the body from the outside as causal agents. He found that at most, they are secondary agents. Bechamp saw that germs do not come from the outside into an innocent body
Sardello draws on Béchamp’s counter-tradition to the germ theory, contending that infection is a secondary rather than originating phenomenon and that the condition of the bodily and soul-terrain is primary.

the flow of the blood, that through the Air element form a continual relationship between inside and outside become subject to opportunistic infection. The processes that maintain the inner warmth or Fire of the body grow weak.
Sardello reads AIDS as the dissolution of the soul’s elemental coherence, rendering the body subject to opportunistic infection — a condition that mirrors the broader evaporation of soul in the contemporary world.

Dr. M. said: ‘It’s an infection, but no matter. Dysentery will supervene… the toxin will be eliminated.’ At first this struck me as ridiculous.
In Freud’s Irma dream, the word ‘infection’ surfaces as a reassurance that is immediately felt as absurd, functioning in the dream-work to deflect responsibility from the dreamer onto somatic causation.

Epidemic fever is koinos, ‘common’ to all, because everyone draws in the same pneuma, ‘air, breath.’ … ‘It is clear the cause is not diet but what we breathe. Plainly it is charged with some diseased exhalation.’
Padel locates ancient Greek proto-theories of epidemic infection in the shared inhalation of corrupted pneuma, showing that the concept of contagion was from its origins bound to ideas of communal susceptibility and environmental soul.

Because the physician continues to link infection with disease and disease with death, he fights—and in the end often defeats his own purpose.
Hillman criticises the medical conflation of infection, disease, and death as a professional deformation that generates iatrogenic harm and forecloses the psychological investigation needed to understand illness.
