Abstract
The Concept of Health in Immunology and Infection Biology: Nine Opportunities for the Future. Looking at our individual immune systems, one might get the impression that health is mostly a personal matter. However, infection biology immediately points to the fact that health is the outcome of a global joint effort undertaken not only by all humans, but actually by all living beings. From the very large to the very small, health is based on a fragile balance and the successful collaboration of numerous single entities in a highly sensitive and complex network that connects our innermost world with that of the outside. Diseases have been with us forever, and in the course of time, they shaped our political and cultural community. Yet, they also are one of the main drivers of evolutionary development. In that capacity, they have promoted progress from simple life forms to complex beings, i.e., ourselves. Thus, health can also be seen as the product of innumerable tiny coincidences. Politics, academia and society should ensure prevention of future detrimental (or harmful) coincidences with such tragic outcomes.
