Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: SARS-CoV-2 is the virus that causes COVID. It has caused a global pandemic. Most people have no to mild symptoms. But some people need to be hospitalized, and a small number need critical care. Older age as well as some socio-demographic factors and chronic health conditions may play a role in the severity of COVID. In this study, researchers want to assess sociodemographic-, population-, disease-, and gene-based risks for features associated with severe SARS-CoV-2 outcomes. As more is understood about COVID, researchers also want to learn more about people s experiences with COVID vaccines, long-haul symptoms, and other related disease features. Objective: To measure the frequency and severity of COVID infection in people with rare and common diseases, looking for conditions that increase risk of severe outcomes. To describe experiences with COVID vaccines, symptoms, and other features of COVID in people with rare and common diseases. Eligibility: People greater than 1 month of age, both with and without rare disease, who have access to the Internet. Design: This study will take place online. Participants will visit a website. They will fill out a survey. It should take less than 30 minutes to complete. They will answer questions about their current health and COVID experiences. They will answer questions about their demographic and location features that may impact their exposure to the virus. All questions are optional. Participants may repeat the survey if their responses indicate a need for follow-up. Participants medical records may be reviewed. Participants may be contacted for future studies related to: COVID Their underlying health conditions A new exposure that is being studied....
