In recent decades, policymakers all over the world have sought to strengthen the meaning and effect of public, non-medical healthcare. This publication is the result of the research initiation project "Arteria Danubia - Analysis and Discussion on the Implementation of Model Health Regions in the Upper and Lower Reaches of the Danube" (2017 to 2019), which focused on healthcare in Bulgaria, Germany and Hungary. In this book, researchers from the participating universities and organizations explore the topic of public health in all its facets: How can public policy and education influence people's health? How are lifestyle-related diseases to be avoided? And how best to implement digital healthcare solutions?
