Summary
This study enrolls healthy adults who are already part of a respiratory virus challenge study at the NIH. Participants wear a smartwatch and use a smartphone to track temperature, heart rate, coughs, and other health signals. The goal is to see if these devices can detect subtle changes that indicate infection, potentially leading to earlier diagnosis.
What this could mean

What this could lead to
If successful, this could lead to wearable-based early detection tools for respiratory infections like flu and COVID-19.
What could go wrong
This is an early observational study, not testing a treatment. The digital biomarkers may not prove reliable enough for real-world diagnosis.
