Nathanael NerodeEveryone who has had #Covid once is now immunocompromised (according to many, many studies) and therefore at higher risk. This is probably over half the US population.
The pandemic doesn't end until we start protecting one another.
Cynde@luckytran @neroden 80% of the population has been infected by the latest estimates. Considering the lack of testing, reporting, and tracing, it’s probably closer to 90%.
Indeed.
Due to the utter lack of valid data collection, I'm not willing to commit to that level of specificity. I know there are some of us who have never caught Covid because we took serious precautions -- and I don't know how many of us there are or how to count us.
@luckytran @neroden We will never know the true numbers. Data has to be captured consistently and universally and that wasn’t even attempted.
