Researchers want to understand how your body's immune system fights COVID-19 and influenza infections. This study will collect blood and mucosal samples (like swabs) from people who have recently gotten sick with either virus, tracking how your immune cells and antibodies change during infection and recovery. By studying these patterns, scientists hope to learn more about how our bodies naturally protect us from these respiratory viruses.
COVID-19 and flu can affect people differently, and doctors don't yet fully understand all the ways your immune system responds to these infections. This research could help improve how we diagnose, treat, and prevent these diseases in the future.

If you enroll, you'll be asked to provide blood samples and mucosal samples (such as throat or nasal swabs) at multiple timepoints: when you first get sick, during your infection, and again after you've recovered. The researchers will analyze these samples to measure immune cells, antibodies, and other immune markers. You'll likely have 2–4 visits over a period of weeks, though the exact schedule will depend on your infection timeline.
