Study Snapshot

The TrackCOVID study is looking for 4,000 adults who live in one of the following Bay Area counties: Santa Clara, San Mateo, Alameda, Marin, Contra Costa, San Francisco.

The purpose of this public health surveillance initiative is to understand how many people are currently infected with COVID-19, how likely it is someone will become infected, and  the body’s immune response to the coronavirus. Having immunity means that you were exposed to COVID-19, and have developed antibodies to the virus. We want to see if these antibodies will protect you from future infection. 

Determining how many people are infected with the virus and how many people have been exposed and have antibodies is essential for understanding the likelihood of future infection and the course of the pandemic. 

This information is vital to informing safe practices as the Bay Area moves away from shelter in place and returns to work and school. We will be providing real-time study results to inform policy makers on timing and best practices for returning to activities in the Bay Area. 

This study is funded by the Chan Zuckerberg Initiative and in partnership with Chan Zuckerberg Biohub
