The University of Southern California and LA County Public Health Department recently conducted an antibody study.

“Based on testing results from 863 adults, the research team estimates that approximately 4.1% of the county’s adult population has an antibody to the virus. Adjusting this estimate for the statistical margin of error implies about 2.8% to 5.6% of the county’s adult population has an antibody to the virus — which translates to approximately 221,000 to 442,000 adults in the county who have been infected. That estimate is 28 to 55 times higher than the 7,994 confirmed cases of COVID-19 reported to the county at the time of the study in early April. The number of COVID-related deaths in the county has now surpassed 600.”
At the time the study was published LA County had 617 deaths. If the antibody sampling is representative of the undetected infections, the death rate would range between 0.00279 to 0.00139 (617 deaths per 221,000 to 442,000 undetected infections).
This also assumes every one of the 617 deaths was linked to Covid-19.
Keep in mind the Lakers played their last home game on March 10 and Disneyland remained open through March 13. The shelter in place likely happened well after the virus was in the community.
