The COVID and Diabetes Assessment (CODA) study is for adults who have been diagnosed with type 1 diabetes or type 2 diabetes within the last 90 days. This study will examine if having a recent COVID-19 infection may impact the course of diabetes. We will gather information about both diabetes and COVID-19 infection. Participants will be followed for 2 years and asked to complete surveys and provide blood samples. No treatment or medications are involved in the study.

This study will involve taking one or two medications already approved by the Food and Drug Administration (FDA) for treatment of type 2 diabetes to learn more about which diabetes medications are the best for lowering the risk of heart and kidney disease in individuals with type 2 diabetes who are at least 40 years old. Participation includes about 8 study visits over a period of 72 months, which can be performed over the phone remotely or during normal standard of care clinic visits. Participants will be compensated for their time and participation in this research study.
