Many orders of magnitude fewer deaths, for one?
Looking at the world instead, COVID has killed just over a million people so far, and Spanish Flu is esimated to have killed anywhere between 17 and 100 million people, at a time when the world population was much less and travel was much harder. So yes, orders of magnitude.
- The average age of death during the 1918 Spanish Flu pandemic was 28 [1].
- 70% of U.S. COVID-19 deaths are age 70 and above [2].
These are very different pandemics, and it's not clear what comparisons between the two actually tell us.
