During the 2019 flu season in Canada, 46k people were diagnosed with influenza. That's not people who "felt sick", that's people who went to their doctor or emergency, had a test done, and were told "yup, that's the flu".
Of those 46k, 2000 had symptoms severe enough to be hospitalized so they could be monitored.
Of those 2000, 600 ended up in ICU, connected to machines to breath for them.
Of those 600, 200 died.
2019 had a fairly average flu season.
During the 2020 flu season, that was 69. Total. Zero hospitalization. Zero ICU. Zero deaths.
The 2021 flu season is almost over and since people were "more comfortable" this year not wearing masks where they should have been the numbers are higher, but still only in the hundreds of cases, with zero deaths to date.
If anyone tries to tell you masks don't work, there are statistically at least 400 people who did not die of the flu who prove otherwise.
