Infectious diseases is an area of medicine that has always been relevant and important in all regions of the world. In recent years, the relevance and importance have been emphasized and heightened by a number of issues, including the emergence of new infections (such as HIV, the novel H1N1 influenza pandemic, avian flu, and severe acute respiratory syndrome) as well as increasing resistance to current established treatments of various infections (such as those caused by Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus species, several gram-negative bacteria, and Mycobacterium tuberculosis). There is a need to provide accurate and up-to-date information to infectious diseases practitioners who are at the front line of the effort against these problems. Mayo Clinic Infectious Diseases Board Reviewis a comprehensive, state-of-the-art publication. Written by practicing Mayo Clinic infectious diseases specialists, the book covers current and essential clinical aspects of diseases likely to be encountered by the infectious diseases specialist as well as to appear on the subspecialty infectious diseases board examination. Relevant and practical information is presented in an uncluttered format with liberal use of tables, diagrams, algorithms, and images as appropriate. While the primary audience of the book is practicing infectious diseases specialists preparing for their subspecialty board examination, the broader utility of this publication will include its use as an update for infectious diseases physicians, as a teaching curriculum in infectious diseases training programs, and as a user-friendly and practical resource in infectious diseases for noninfectious diseases physicians and health care providers. This publication will be a useful resource not only in the United States but throughout the world.
