"The many diseases that are endemic in most of the developing nations of the world (and that may also affect travelers to these regions) are, at world levels, the most important sources of morbidity that affect the entire human race. The change in morbidity patterns in the more developed nations should not be permitted to blind the more affluent countries to the implications of this simple statement. Thus, direct and useful guides are needed to assure efficient and economical diagnosis and treatment of those infections that are endemic to the less affluent two-thirds of the earth.

"The algorithms in this book have been developed by Drs. Warren and Mahmoud, as the result of a systematic effort to produce such guides. The book is presented as another in the series "Studies in Infectious Disease Research" and is a most welcome addition, certain to supply a major and hitherto inadequately fulfilled need."—from the Foreword, by Edward H.
