We think the Spanish Flu ended in 1919. But it didn't. People just got sick of fighting it and reporting it in 1919. The 1920 variant was even more lethal, because of that collective giving up. This same thing then happened again multiple times across the rest of that century, and into the 21st century. And has eerie similarities with us right now, with Omicron. https://www.nytimes.com/2022/01/31/opinion/covid-pandemic-end.html
