The Epstein-Barr virus for example can make you tired for months or years.
I am not saying long Covid isn't a thing, but it is not 'special' in any way.
Virus infections can cause damage. Years ago I had an infection that damaged a nerve. So virus infections can leave marks. But most of the time, as with Covid, you will recover from it.
But isn't COVID novel in the damage it poses to microvascular systems (importantly brain and lungs), compared to other viruses? E.g., https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7556303/
My understanding is that this is still different from other viruses.
So if large swaths of a country get that damage from delta vs omicron vs some future weaker variant, that could have very different public health consequences in the coming decades...
Disclaimer: In tech for over a decade, but once upon a time I did an honours degree in biochemistry, so I'm only maybe half-capable of musing my way through some of these papers :)
Maybe. But I suspect actually the reverse is true. "Normal" viruses (virii?) are probably far more damaging than we have ever credited.
The fact that we can vaccinate against a cancer (cervical cancer) and the fact that asthma went down more than expected during lockdowns, suggests that we are significantly underestimating the risks that "normal" pathogens incur.
