The purpose of this study is to describe the long-term health effects of COVID-19 in a population of mostly Black and Latinx individuals and their households who were diagnosed with COVID-19 at Columbia University Irving Medical Center. In New York, the upper Manhattan and south Bronx communities neighboring Columbia University Irving Medical Center (CUIMC) have been two of the most impacted communities of the COVID-19 pandemic. These neighborhoods are predominantly non-Hispanic black or African American and Latinx. This study will invite people who tested positive for COVID-19 and/or were treated at Columbia University Irving Medical Center to: 1) take a survey to ask about current symptoms and any health problems and 2) ask permission to review COVID-related health history including COVID-19 testing results (from the medical record) since infection to learn about health effects after COVID-19 infection; 3) invite anyone in their household to take a survey; and 4) for up to 500 patients who were hospitalized for COVID, give the option of doing a nasal swab to test for SARS-CoV-2 virus and blood test to check for antibody up to 12 months after diagnosis, to compare how results are different 12 months after infection. The goal is to learn about how the severity of person's infection in 2020 influences long term health effects and how others in their household are impacted by COVID-19.
