I don't really understand why it's linked.
We are making the claim Covid-19 has a really low mortality, much lower than the 1% claimed. But even at 1% your link in not relevant.
So the question stands to the downvoters, one fucking link?
Are you all Russian trolls? Why do you think covid-19 does permanent damage. Where is this coming from? I've linked the only study I've seen.
