Infection and psychiatric illness
“Recent immunologic, epidemiologic, microbiologic and
neuropsychiatric studies point to infectious etiologies of
several important neuropsychiatric disorders…several
infectious diseases including human influenza virus, HIV,
syphilis and Lyme disease are associated with
neuropsychiatric symptoms following transmission of
infectious agents to the central nervous system.
…evidence also points to potential for peri-, pre-, and
postnatal infections as causes for several
neurodevelopmental disorders.”

Infection and chronic illness
“…infection may simply represent the first misstep along a
continuum from health to long-term illness and disability.”
“…infectious agents likely determine more cancers,
immune-mediated syndromes, neurodevelopmental
disorders, and other chronic conditions than currently
appreciated.”
“If a mere 5% of chronic disease is attributable to infectious
agents, in the US alone 4.5 million of the 90 million people
living with chronic disease might benefit from strategies
designed to prevent or appropriately treat selected
infections.”
