This book highlights the elements of armed conflict that cause the re-emergence of infectious disease in conflict-affected countries and how the breakdown of public health infrastructure within a country leads to public health challenges for those in countries hosting displaced persons. By examining the connection between destruction of public health infrastructure in Syria, the re-emergence of previously controlled infectious diseases, and the impact of the Syrian forced migration on the EU, this book recommends targeted policies that the EU should enact for more effective protection of health for displaced persons and the host population.
