COVID-19 Community Research Partnership - Study Results and Data

Our goal is to enroll a representative sample of participants from our region in the COVID-19 Community Partnership Research study over the next few months, with particular interest in the elderly (age 65 and older) and racial/ethnic minority groups. The data below reflects study participation since April 2020. Additional data will be included in the future.


Updated 1/14/2021

  • Current study enrollment: 23,235
  • Study participants who have at least one antibody test result: 9,015
  • Percentage of antibody test participants with at least one positive antibody test: about 10%
  • Percentage of antibody test participants who have had a positive test in the last week: about 6%
  • Completed daily symptom logs since the study began: 3,004,995

See more explanation about these numbers below.

Study Participants Who Have the Antibody

Cumulative Percent Seropositive Among Participants

More About This Chart

There are more than 23,000 participants enrolled in the study. About 9,015 of them have taken at least one antibody test - this is shown in green. Of those 9,015 who took an antibody test, about 909 (about 10%) of them have had at least one positive antibody test - this is shown in blue. This number will continue to grow. To have a positive antibody test means that a person has previously been infected with COVID-19 and has developed an immune response to the virus. We cannot determine with these tests if someone is actively infected with COVID-19.

NOTE: There’s been dip in “% of Participants Tested Positive” as a result of an increase in new study participants who have not yet completed their first antibody test. The total number of participants with at least one positive antibody test continues to increase – currently 909.

Positive Antibody Tests Per Day

This chart shows the number and percentage of participants who tested positive on each day during the study as well as the weekly average of positive tests.

 Daily Rates of Antibody Tests

More About This Chart

There are about 9,015 participants who have taken at least 1 antibody test. Most of those 9,015 participants have taken several antibody tests – each participant takes a test approximately every 2 months during the study. 

Each day, we get results for between 5 and 373 antibody tests – these are represented by the blue bars above. Each day, the number of positive tests is between 0 and 24 – these are represented by the red bars above. 

The dark blue line shows the percent of tests that were positive in the previous seven days. Over the course of the study to date, this number has moved between 0 and 10%. Note the percentages are on the right side of the chart.

Ethnicity Breakdown of Participants

We recognize that people of color continue to be underrepresented in research, including this study. To address this concern, we have partnered with several community-based organizations to increase access to the study and raise awareness about COVID-19. We will continue to work to increase representation from African American and Latinx community members to ensure we have adequate data to better understand how COVID-19 is affecting members of those communities.

More About This Chart

There are more than 23,000 participants enrolled in the study. Approximately 90% of them are White. People of color represent about 10% of the total study participants. This pie chart reflects the demographics of participants who have activated their account and given at least one status update for symptom tracking (n=21,042).

More About This Chart

A subset of the participant population has been selected to receive antibody blood tests. We sampled participants to ensure demographic representativeness based on Census tract data and oversampled for African American and Latinx groups. Of the total 23,000 participants, the study has sent antibody tests to 9,015 participants. Of the 9,015, approximately 86% of them are White and 14% are people of color. People of color are still underrepresented in our study. As a result, any person of color who enrolls in the study will be selected to receive antibody tests to ensure we adequately understand the effects of COVID-19 on these populations.
