Welcome to the DFW COVID-19 Prevalence Study

Read the news release about this study

UT Southwestern, in partnership with Texas Health Resources, local organizations, and community leaders, is leading groundbreaking research to understand the spread of the novel coronavirus: the DFW COVID-19 Prevalence Study.

Millions of people all over the world and in the United States, including thousands in North Texas, have tested positive for COVID-19. Many more have been infected, do not have symptoms, and do not know they are passing the virus to others. The number is still climbing, with more outbreaks of the disease expected.


Understanding who has COVID-19 and how it spreads

One of the major challenges to stopping the spread of COVID-19 is a lack of information – including where the virus is spreading and why certain people are more affected than others. For example, current data shows a disproportionate number of illness, hospitalizations, and deaths among African Americans and Latino populations, as well as low income individuals. However, little information exists to explain why this is happening.

With the DFW COVID-19 Prevalence Study, our goal is to understand how many people actually are or have been infected in our local North Texas community and help develop effective and fair public health strategies to reduce any further deaths related to this disease. We believe data from this study will help inform what needs to be done to open our economy safely and to return to our normal lives.


Watch Your Mail

Unlike other COVID-19 studies that used a volunteer sample, participation in this study is by invitation only and will comprehensively recruit residents and essential workers from throughout Dallas and Tarrant counties. This will ensure that study results accurately represent our diverse communities in terms of socioeconomic status and race/ethnicity.    

Letters inviting people to be part of the study are in the mail. For anyone that receives one, it’s important to respond quickly and answer the call.

Why Is COVID-19 Affecting Racial and Ethnic Minorities More?

UT Southwestern and Texas Health Resources are conducting a study to determine why nearly three out of four patients hospitalized because of COVID-19 are African American or Latino – groups that together make up only two-thirds of the DFW population. Researchers are focusing on this disparity and need your help.

Understanding the Prevalence Study

If you are one of the 45,000 Dallas or Tarrant county residents invited to participate, you'll receive free testing for COVID-19 and its antibodies.
