ABSTRACT
Concluding the final chapter of his heroic history of The Conquest of Epidemic Disease, C.-E.A. Winslow wrote:
There is today a wholesome reaction against exclusive emphasis on the germ and recognition of the importance—even in many germ diseases—of factors of constitutional resistance (diathesis) and of the influences of climate and season and nutrition upon vital resistance (Winslow, 1943, pp. 379–80).
