Research survey for rare disease patients and their families about impacts of COVID‑19

The Rare Diseases Clinical Research Network (RDCRN) is conducting a study to help researchers understand the impacts of COVID-19 on the rare diseases community. This dashboard displays interim results from the study. It will be updated frequently. Learn more about this study or take the survey.

Number of surveys completed, by state. People with rare diseases from all over the country have participated in the survey.
Number of surveys completed, by date completed. We hope that 5,000 people who live with rare diseases will complete the survey by July 31, 2020.
Survey respondents have many different rare diseases. The bubble plot shows respondents with diagnoses studied by individual consortia or research teams within the Rare Diseases Clinical Research Network. The names of the consortia with 50 or more completed surveys are reported in the plot. Find a complete list of consortia here.
Ten most reported diseases by people who have completed the survey. Rare diseases are not rare — an estimated 30 million people in the United States are affected by rare diseases.
Survey respondents have many different rare diseases. This table provides a list of all the diseases reported by people who have completed the survey.
