Facebook CEO Mark Zuckerberg is funding a significant increase in coronavirus testing in the San Francisco Bay Area through two philanthropic groups he manages with his wife Priscilla Chan, the chief executive announced today on his personal Facebook page.

Chan and Zuckerberg are organizing the funding through their philanthropic groups, the Chan Zuckerberg Initiative and the Chan Zuckerberg Biohub. The latter is dedicated to helping combat and research diseases and works in partnership with the University of California, Berkeley; the University of California, San Francisco; and Stanford University. Chan and Zuckerberg started it in 2016 with $600 million in funding from the Chan Zuckerberg Initiative, which is the couple’s main philanthropic arm.

Effectively, the philanthropic groups are purchasing two diagnostic machines that are Food and Drug Administration approved for testing for diseases like COVID-19, the illness caused by the novel coronavirus, according to the San Francisco Business Times. UCSF will conduct the tests, while Stanford University will act as a secondary location for test requests when the city is overwhelmed.

Zuckerberg’s move follows that of Microsoft co-founder Bill Gates’ similar push to use private funds to make up for the severe limitations currently on federal government testing through the Centers for Disease Control and Prevention. The CDC notably botched early testing kits and failed to issue more preemptive testing protocols that may have drastically reduced the spread of COVID-19 in the US in the first weeks of its discovery.

The Bill and Melinda Gates Foundation announced on Monday that it’s partnered with the University of Washington to fund at-home testing kits for COVID-19 for residents in the greater Seattle area where COVID-19 first surfaced in the US and where the highest number of domestic confirmed cases and deaths have been recorded. The Gates Foundation will do this through its funding of the Seattle Flu Study, with the goal of reducing the exposure of health care and medical professionals to potentially infected individuals and more broadly providing testing resources to the hardest-hit area of the country.

There is no clear date for the Gates Foundation’s initiative, but a representative for the organization told The Verge, “Our team has and will continue to actively explore ways that we can contribute to the local response through the application of this study.”

The Chan Zuckerberg Biohub is expected to start increasing the testing volume in the Bay Area as soon as March 16th. Here’s Zuckerberg’s announcement in full:
