This book was revised for a second edition in 2003 (originally published in 1989). It contains probably everything you would want to know about the 1918 pandemic and is very thorough in research and notations. Great to read and see how THIS flu was able to kill almost 700,000 Americans in about 1 year. Remember as almost everyone at the time said "it's just the flu". Some stories will sound familiar as we go through the Covid 19 Pandemic 100 years later, the "mask" controversy and the fact that the spread went rampant except in a few places on the earth where "quarantine" or "Lock down" took place weather by choice or by geographic constraints. Excellent book.
