Researchers want to understand how COVID-19 affects your gut bacteria and whether the virus can be found in stool samples. This study will collect stool samples from people currently being treated for COVID-19, both during their illness and after they recover, to see if and when the virus appears in digestive samples.
Scientists don't yet fully understand how COVID-19 affects the digestive system and gut bacteria, or whether the virus sheds through the intestines. This research could help doctors better understand how the virus spreads and how it affects the body beyond the lungs.

You would provide stool samples at different timepoints — some while you're being treated for COVID-19 and again after you've recovered. The samples are collected at home in a simple kit and sent to the lab for analysis. Your participation helps researchers understand an important gap in COVID-19 research without requiring you to take any medications or undergo procedures.
