When one reads about the challenges facing humanity this century, it becomes clear we must do more with less. A growing population must be provided with welfare while using fewer resources, particularly water, land (working surface) and energy. An aging population, chronic degenerative diseases, addictions, healthcare costs and the integration of health systems all entail challenges in the health department. However, we must not forget the presence of old and new infections that “threaten” to become pandemics. Here I will address the subject of global epidemiology and, in particular, the risk of what can be termed “global” pandemics, as was the case, a century ago, of Spanish influenza. By conservative estimates, this killed 50 million people (some sources estimate double the number of deaths).
