@kellymcevers A segment on NPR One today interviewed the author of the LA County serological survey study - I would point you to #EpiTwitter. The folks over there have voiced a good amount of criticism over the study’s methodology, particularly its confidence interval.

Meaning, the findings that 4% of LA’s population has SARS-CoV-2 antibodies are misleading because the lower bound of that confidence interval (for a variety of reasons including the reliability of the sero test results) is 0%.

I would point you to this thread to begin with.
