ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the research from five continents and a mixture of chapters that focus on national case studies and those that take a more global perspective. One of the diplomatic terms was the establishment of leased territories, mainly ports. Japan set up three leased territories where the Japanese administrative rules were applied. Koreans were regarded by the Imperial countries, such as Japan, Russia and Britain, as potential spreaders of infectious diseases that should be controlled. The defense method of creating a safe zone was reproduced in the quarantine strategy of the Japanese Government-General of Korea following annexation in 1910. The opening of the ports ushered in a new awareness of infectious diseases coming from outside Korea. As the era of the discovery of microbes progressed, the modern hygiene policy gained critical weapons in the form of vaccines and the isolation of pathogens.
