Wow, another seroprevalence study, this one in Los Angeles! @LAPublicHealth estimating 4.1% of the county's adult population has antibody to the virus. This would seem to match the earlier @Stanford @USC Santa Clara County estimate. https://buff.ly/2RTkEDM  HT @zakkohane

Since more people are seeing this, want to make sure folks know it’s a similar set of authors to the study several days ago from Santa Clara County, which has had a lot of questions raised. This one doesn’t even have a preprint yet, but it is a press release from @LAPublicHealth.
