The Coronavirus Disease 19 (COVID-19), which emerged as pneumonia from an unknown agent for the first time at the end of 2019, has dramatically transformed our world into one that is highly unrecognizable today. Newly emerging infectious diseases have been occurring more frequently than ever. Opportunities of such deadly microorganisms to adapt to humans—as well as spread between people on a massive scale—are growing because of active human mobility. We have translated and published the book, “One Health: People, Animals, and the Environment.” The original book, published in 2014 by ASM Press, shows the concept and applications of One Health. The current book comprises five parts: definition and importance of One Health, zoonotic and environmental drivers of emerging infectious diseases, One Health and antibiotic resistance, disease surveillance, and realizing the One Health Initiative’s objectives. This translation and publication was the first science book publishing project performed under the name of the Korean Society of Clinical Microbiology. We are actively working toward providing academic information and advancing our identity in other scientific fields as well as to the public.
