This unique guidebook and reference will enable physicians to develop an informed differential diagnosis of patients who have lived or traveled in other countries or who have had exposures that could lead to infections with unusual or unfamiliar pathogens. It draws together information from many diverse sources in an accessible format that will foster a logical clinical method. The first section of the book outlines a systematic approach to the patient's history, analyzing factors that affect probability of infection, with an evaluation of clinical findings. The second section presents a profile of infectious diseases for every major geographic area of the world, giving supplemental information for each country discussed. The third part describes key features, including epidemiology, clinicopathologic findings, diagnosis, and management of 235 infections. Valuable appendix materials define important terms and give practical information on incubation periods, vectors, transmission via blood transfusion and pathogens in foods.
