Stanford study: More than 48K Santa Clara County residents have likely been infected by coronavirus

AFM · Apr 18, 2020

A study out of Stanford University has indicated that the number of coronavirus infections in Santa Clara County, California may be 50 - 80 times higher than the officially confirmed number. Based on a survey of blood samples 2.49% to 4.16% of county residents may have coronavirus antibodies This suggests that the infection mortality rate may be in the range of 0.12% - 0.2%. This is much less than the infection mortality rate of 3.9% calculated from official cases and deaths.

The prevalence study, led by Stanford Assistant Professor Eran Bendavid, has not been formally published and is still undergoing peer reviews. It has, however, been published on the preprint server medRxiv. As such, it is effectively a first draft, subject to change based on input before formal publication.

That said, the early findings indicate that between 48,000 and 81,000 residents in Santa Clara County were infected as of April 1, back when the official count was 956. The estimate is based on 3,330 blood samples that were taken from volunteers in Mountain View, Los Gatos and San Jose on April 3 and April 4 and tested for antibodies to SARS-CoV-2 . When adjusted for Santa Clara County's population and demographics, the number of positive results suggests that between 2.49% and 4.16% of the county's 1.93 million residents have had COVID-19.

The study's results "represent the first large-scale community-based prevalence study in a major U.S. county completed during a rapidly changing pandemic, and with newly available test kits," the authors wrote.

The most important implication, the preprint notes, is that "the number of infections is much greater than the reported number of cases."

"The population prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that the infection is much more widespread than indicated by the number of confirmed cases," the researchers concluded. "Population prevalence estimates can now be used to calibrate epidemic and mortality projections."

Given the study's estimate of 48,000 to 81,000 infections in early April – and a three-week lag from infection to death – the 100 deaths suggest that the infection fatality rate is between 0.12% and 0.2%. That's a far contrast from the county's mortality rate based on official cases and deaths as of April 17 -- 3.9%. (And for comparison, the nation's mortality rate for influenza during the 2018-19 season was roughly 0.09%, according to the Centers for Disease Control and Prevention based on preliminary data.)

The study states that the new data "should allow for better modeling of this pandemic and its progression under various scenarios of non-pharmaceutical interventions."

It's vital to keep the fear mongering from the Left in full force.

I liken their attitude to the Russian BS, PeePee tapes, Mueller report, Kavanaugh hearings, Impeachment joke, and how many other engineered drama events I may have missed.
