COVID-19 Study

Frequently Asked Questions


Below are frequently asked questions about the DFW COVID-19 Prevalence Study.

If you have questions that are not related to this study, please see additional COVID-19 information on our website. UT Southwestern is actively responding to the spread of COVID-19, and our infectious disease physicians are leading efforts to keep patients informed, educated, and safe.

Why is this study being conducted?

To stop COVID-19, we must have more information. We need to understand where the virus is spreading and why certain people are getting it more than others. For example, we know that COVID-19 affects more African Americans and Latinos. We also need to know how long COVID antibodies remain in people who have had COVID and why some people have symptoms long after infection (i.e. “long-hauler” symptoms).

Why is the study closed for new enrollment?

With the Community Advisory Board and community partners support, we successfully enrolled enough volunteers to assess prevalence of infection in various demographic groups. Resources are now being devoted to longitudinal analysis to understand how long antibodies remain in people and why some people continue to have symptoms.

Why are some people invited for repeat testing?

We are currently inviting a group of people to come back and have their COVID antibody levels rechecked. This group is made of people who had positive antibodies, active COVID infection, or told us they had previously been infected with COVID. We are also inviting some people who had negative COVID tests to see if they have developed antibodies. If you are in either of these groups, a member of our study team will contact you.

Will my results be shared?

Your participation, answers, and testing results will be kept private. They will only be shared with the study’s scientists. Your name will not be listed in any study reports, which will sum up the findings of all who volunteered for the study. We will share the reports with you and community leaders via this website.

Are study data available to outside researchers or other third parties?

Although we cannot share primary study data to preserve privacy of participants, we encourage outside researchers contact us if they are interested in collaborating on related research questions.
