- infection always results in death or immunity (unproven, but no evidence of repeat infections yet)
- official COVID-19-related death counts are accurate (142k at the time of this question)
How close is the U.S. to achieving herd immunity to COVID-19?
The CDC has published estimates of infection rate, mortality rate, etc. However, I haven't yet seen anyone actually do the math of how close the U.S. is to herd immunity.
