Evolutionary nursing: the case of infectious diseases

Edward Purssell · Journal of Advanced Nursing · 2005

Aim. The aim of this paper is to examine the effect of evolution on infectious diseases nursing, and propose a model that may help to increase understanding of how hosts and microorganisms co‐exist and how humans can alter the delicate balance between them.Background and rationale. Infectious diseases occur as the result of interactions between hosts and microorganisms. There is an increasing acceptance that the evolution of host and parasite is important in the development of infectious diseases. However, such views have made little impact in nursing, and the use of evolutionary interventions remains controversial.Method. The Medline database was searched from 1966 to present using the terms pathogen$, virulen$, evolution, bacteria, and all combinations of these. Additionally reference lists of text books and papers were hand searched for relevant papers. Papers were selected from a variety of disciplines, including infectious diseases, microbiology, evolutionary biology, and ecology. Recurrent themes from these papers were identified and a model of evolutionary nursing constructed.Results. Microorganisms are plentiful, ubiquitous, and rapidly evolving by comparison with humans an
