This study is looking at how data from wearable devices, like a Fitbit or Apple Watch, can help understand respiratory viral infections (RVI) such as the flu. The study will happen during the 2023-2024 flu season in the United States. Participants will wear their device daily for at least 10 hours and answer questions for 10 weeks. They'll also need to do at-home nasal swab tests when asked.
Key Points:
- The study lasts 10 weeks and requires daily device use and answering questionnaires.
- Participants must own a compatible wearable device or use a provided one and have a smartphone with specific software.
- Exclusions include recent flu or COVID diagnosis and participation in certain other studies.
