From aggressive testing of cooped-up populations in homeless shelters and prisons, we are beginning to learn the true prevalence of the virus. It remains to be seen how many of the inmates will develop major symptoms.
This widespread prevalence of the disease is hopeful news in one sense – if so many people have it and haven't keeled over and died, the true case fatality rate is probably relatively low.
However, the flipside is that the long-term disability rate might be high. We simply don't know what disabilities people may be left with, or what sequelae to the infection may manifest in future.
In a very worst case scenario, this might even be harder on society than if people simply expired outright. Our civilization can absorb the deaths of 5% of people, as tragic and difficult as that would be. However, it might not absorb the disablement of 25% of the workforce – hands that cannot work yet have a mouth to feed and a back to clothe.
That's a high figure, but that's the approximate rate of persistent clinical-grade chronic fatigue for SARS classic survivors:
