Abstract
Dr G I Watson considers the many facets of clinical and immunological response to virus infections in man. These are illustrated with examples from his practice.
Dr R E Hope-Simpson describes the ways in which viruses have become adapted so as to ensure their survival as parasites. These embrace the effects of urbanization, adaptation to a different habitat, reduction in infectivity and the development of mutants.
Dr P G Higgins considers the role of the laboratory in diagnosis and treatment of virus infections. He outlines the best ways in which general practitioner and virologist can co-operate in this field.
