- PaulDavisThe1st 4y agoNope. I'm saying there was no way to know who had any level of natural immunity to SARS-COV-2.
- origin_path 4y agoThe topic was never explored so we don't know if there was no way to know. Instead, epidemiologists just assumed 100% susceptibility, droplet transmission and no seasonality, i.e. that everyone would get infected all at once in one giant wave. This was wrong and also, in contradiction with all pre-existing knowledge of both how coronaviruses work and how SARS-1 worked (SARS-1 was airborne over long distances).
