It's amazing how people have consistently acted throughout 2020 as if coronaviruses are entirely new, never seen before and everything known about the immune system or viruses has to be thrown out.

People have been getting infected with coronaviruses of various kinds for millennia. Nobody has ever linked a low severity cold-like infection with long term severe consequences, and given the sort of longitudinal study that would be required to establish such a link, any such claims would need to be treated very carefully.

It is amazing how wannabe public health experts, with zero expertise in virology, are failing to understand that difference just in handful of nucleotides may make the pathogen a completely different beast compared to its nearest relative. And we are not even talking about the nearest relatives, common cold coronaviruses diverged like many thousands years ago from the SARS1 and similar viruses.

Nonetheless, the original SARS-1 (which is way closer to SARS-2 than say OC43), is known to be causing long term, debilitating health complication among significant number of survivors.

It's not a completely different beast, is it? It's basically like a regular flu or severe cold, and yes rhinovirus can be deadly to the elderly, it's just nobody normally notices or cares because rhinovirus isn't "new". If anything it's actually less bad than flu because flu kills children too and this one doesn't.

And yet it didn't turn into a worldwide outbreak, so one must ask how much value this classification scheme actually has, given that SARS-2 is really nothing like SARS-1 in either infectiousness nor severity.

I usually stop arguing when I know that no one reads the discussion, because it is pointless at this moment, for the reason of me having no intention to convince you in anything, if you fail to see obvious things. I think we need to stop - no one is reading our conversation anyway.
