Pandemic 1918, by Catherine Arnold.

First published in 2018 this eye-opening book tells the story of the Spanish Flu, as see by those alive at the time. Meticulously assembled from the testimony of those who lived, died, and tended others, set against the media and political response at the time. It's impossible not to be deeply moved, and impossible not to see parallels – and to wonder whether, if our current world leaders had read this book when it was published two years ago, we might be in a better place now.
