People in general are concerned about the health of themselves and their families, but they lack reliable access to health knowledge. In order to ensure that people get accurate medical knowledge, dissemination of such knowledge by medical professionals is advocated. This is the basis of medical communication. This book covers the theoretical model of medical communication, explains the differences from medical science popularization and health communication, and from the perspective of medical practice, provides many examples to illustrate the practical application and significance of medical communication. It is hoped that this book will attract more people to join the team of medical communicators, pass the correct medical knowledge to the public, and ultimately the incidence and mortality of diseases can be reduced and the health level of people improved.
