The Invisible Enemy

"In this book, Professor Crawford explains all about the natural history of deadly parasites and discusses controversial subjects such as chronic fatigue syndrome and Gulf War Syndrome. The book then considers more general issues such as how man has coped with viruses in the past, where new viruses come from, and whether a new virus could wipe out the human race. In the last chapter the author attempts to answer the vital question; who will be the final victor - man or virus?"--Jacket.
