This is where Covid is listed on the death certificate as the primary cause of death. Everyone that dies of cardiac arrest or cancer also has a belly button.

> While it's important and long past-due that post-infection syndromes are finally getting the attention they deserve, there is no evidence that this particular coronavirus is different from other four endemic coronaviruses (and several other pathogens) in this regard.

Generally there hasn't been all that much research on post-viral syndromes. To some degree that's because they don't obviously affect so many people. It could very well be that other viruses are the cause of more conditions than is currently appreciated though. Certainly the Epstein-Barr/MS results could be the tip of the iceberg. Regardless of what other viruses do, it's looking to me like Covid is likely to be pretty bad long-term, but we won't know for sure for 30+ years I suppose.
