It doesn't even have to be worse than post-viral syndrome caused by other severe viral infections for it to be a problem. There's little immunity to COVID-19 and it's highly contagious. This is like saying "COVID isn't worse than the flu" - even if it was true, having another flu-sized disease burden would already be bad, so it's a bit of a weird goalpost. That being said, there's a lot of literature describing post-covid symptomes and hypothesized mechanisms of action, like [1]. The virus has been around for less than a year, so a quantitative comparison with something we have studied for decades makes no sense.

>It doesn't even have to be worse than post-viral syndrome caused by other severe viral infections for it to be a problem. There's little immunity to COVID-19 and it's highly contagious. But it does make it highly inconsistent to adopt policies so extremely destructive to economic and mental health when the same wasn't done for other viruses with similar long-term effects.

  We have a chance at eradicating COVID-19, unlike other viruses that have been endemic for decades.

    How would we eradicate a virus that has animal hosts? If the prevailing origin hypothesis is correct then the virus is presumably still circulating among horseshoe bats.

      SARS-1 has been eradicated in humans;its precursor still probably is circulating among bats.

That depends on what you mean by "little immunity". Many people appear to have some immunity based on prior exposure to similar coronaviruses. That won't prevent infection but tends to reduce disease severity. https://www.jci.org/articles/view/143380 https://www.jci.org/articles/view/143380

  That "some immunity" is clearly insufficient, because people who actually got infected with Covid itself and then again with Covid, in many if not most cases have more severe symptoms. In fact, the scarce evidence suggests Covid might be a subject to Antibody Enhancement; that would mean that every next infection will get worse and worse. In any case, Coronaviruses have long be known to cause very short term immunity. Even more importantly, constant reinfection may debilitate the organism so much, that even a healthy person will eventually fall into the risk group.

    That is unscientific fear mongering. As with any virus there will be some outliers. But in general there is no evidence of widespread antibody enhancement. Reinfections are rare, and most reinfected cases have minor symptoms. https://www.jimmunol.org/content/early/2020/09/03/jimmunol.2000839 https://www.jimmunol.org/content/early/2020/09/03/jimmunol.2...
