This book was originally written in the 1970s, and although it is a "New Edition" it doesn't appear that the text has been updated at all. This means that the scientific information in the book is badly out of date; we know much more about viruses in general and the flu virus that caused the 1918 outbreak in particular than the book says. If you are not concerned about more up-to-date science, the rest of the book is adequate.
This isn't nearly as good a book as John M. Barry's "The Great Influenza". That book is a more compelling read, and has the virtue of being written more recently so it has better scientific information. I would recommend that book much more strongly than this one, if you are willing to read a longer book.
However, this book is shorter, only 350 pages (about 1/3 of those taken up with references) to the 550 pages of Barry's book, and is easy to read. If you want a quick overview of what happened and how the flu spread, it's worth reading.
An exciting book that will satisfy fans of science, history, or just interesting stories. Fully explores the confusion and frustration surrounding one of the most devastating waves of disease to ravage the nation.
