I am not 100% certain you can say that.
I do not believe they have kept the same kinds of stats on long term damage from seasonal flus because they may not have attributed such things to the flu virus or they may have blamed the damage on something else the person had or acquires that can cause the same type of damage. further the flus each year aren’t the same so its not just a 1:1 disease type comparison, which might also be the reason they have not ever kept stats of this nature.
I have been looking for the numbers bu so far haven’t found anything. Which at rhis point prompts me to think they haven’t kept stats like this for the seasonal flus.
Okay, let’s just look at the heart damage. The British Heart Association studied recovered patients in 69 countries and found permanent heart injury in 55% of them. Are you suggesting that the typical flu causes injury anywhere approaching that? Come on.
