This is one of the most useful books I have seen. Each chapter of this book summarizes each infectious disease briefly, and comprehensively, including its ICD-9 and ICD-10 codes. The main focus is on public health response to the event of one case, for uncommon diseases, or the event of a cluster of cases for those more common infections. It is particularly useful for people working in the public health field such as health departments or researchers. However, it is also very handy for clinicians that want to know how to react in front of diseases that may not be common anymore. Specially useful is the chapter on surveillance and reporting. If you want to have one good and simple consulting book on infectious diseases, "Control of Communicable Diseases Manual" is the book you should own.
