PBS is currently streaming (for free) "Influenza 1918", part of their excellent series, American Experience. I understand it's also available on Netflix and Amazon.
This is an excellent documentary on the 1918 flu epidemic that killed over 600,000 Americans -- more than all the wars of the 20th Century combined. It's well worth a watch, especially for those (unfortunately, far too many) who remain in denial or are just ignorant about epidemics, what's currently happening, and what's at stake.
I watched it last night. I noticed many, many echoes of things I see and hear every day now from friends on social media, here in this forum, in the national government, and elsewhere -- denial, obfuscation, "optimism", and unfounded hope replacing reason.
Trailer here (link to the full program is at top).
This program is very well done, and well worth your time to watch, especially if you don't know much about the 1918 flu epidemic or epidemics in general.
I hope someone finds this useful.
