Researchers at the University of Chicago want to understand why some people develop long COVID—symptoms that persist months after a COVID-19 infection—while others recover fully. This study will collect blood and stool samples from 400 people (200 with long COVID symptoms and 200 without) to examine how COVID-19 changes the bacteria in your gut and how those changes might affect your immune system and overall health.
More than 10 million Americans still experience long COVID symptoms like fatigue, brain fog, and heart problems. Current treatments are limited because we don't fully understand what causes these lasting effects. This research aims to identify the role of gut bacteria changes in long COVID, which could eventually lead to new, more effective treatments.

If you join this study, you'll visit the University of Chicago Medical Center or participate remotely to provide blood and stool samples. Some participants may also have an optional endoscopy (a small camera procedure to look inside your digestive tract) as part of routine care. The study involves one main visit to collect samples, though researchers may ask follow-up questions about your symptoms and health history. The entire process typically takes a few hours.
