What we found was quite interesting.

This is the pre-February 22 2020 opening paragraph of the 'Mortality' section on the Wiki page for the Spanish flu (our emphasis):

The global mortality rate from the 1918–1919 pandemic is not known, but an estimated 10% to 20% of those who were infected died (case-fatality ratio). About a third of the world population was infected, and 3% to 6% of the entire global population of over 1800 million[51] died.[2]

This is how the same paragraph reads now:

It is estimated that one third of the global population was infected,[2] and the World Health Organization estimates that 2–3% of those who were infected died (case-fatality ratio).

That's quite a big change in a pretty short time.
