STRESS ENHANCES SUSCEPTIBILITY TO INFECTION, ESPECIALLY TO COXSACKIE B VIRUS

This section addresses the evidence from a primarily viral aspect -- the section on psychoneuroimmunology addresses the evidence from an immunological aspect.

There is substantial evidence that concurrent stress at the time of viral exposure leads to more severe disease; this is well‑established in the medical literature.

Stress is known to increase susceptibility to those diseases which are immunerelated, e.g.. infectious diseases, cancer and autoimmune disorders.

There is an enormous literature on the mechanisms whereby both viruses and stress affect the competence of the immune system.

For example, cortisol (which is greatly increased during acute stress) inhibits the synthesis of a protein (interferon) which can interfere with virus replication, i.e.. adrenocorticol hypersecretion brought about by acute stress is known to have an adverse effect on viral replication.

Physical trauma in man is expressly mentioned as a known route for this adverse mechanism.

NB. Most of the following papers in this section relate to animal (not human) models ‑‑­prospective studies in humans are limited, since it can never be ethical to subject human beings to severe stress and then deliberately introduce a viral agent purely for research purposes.

For the most part, extracts only are included in this section. The full papers are available if required.
