Editor’s Note: The Wuhan coronavirus currently doesn’t appear to be nearly as lethal as the 1918 Spanish flu. The danger is that it could mutate and become more contagious and lethal. In any case, it is a good time to remember the 1918 flu because Americans are as oblivious to the threat of disease now as they were back then. The 1918 flu shattered that false sense of security and killed more people than all the wars of the 20th century combined. Especially the second wave of the virus.
