This observational study aims to understand how wearable devices, like smartwatches, can help detect subtle health changes when people are infected with respiratory viruses such as influenza or coronavirus. Researchers want to see if data collected from these devices, like cough patterns, heart rate, and temperature, can be used to predict when someone is getting sick or how severe their illness might be. You can join if you are an adult between 18 and 65 years old and are already participating in, or planning to participate in, a separate respiratory virus challenge study at the NIH Clinical Center. The main goal is to see if the device data matches how sick people feel and if it can predict influenza infection.

Study design

This is an observational study with a planned enrollment of 1000 participants. It is not a treatment study but rather focuses on collecting data using digital devices.

What's involved

You will need to wear devices as instructed during your inpatient stay (at least 9 days) and during 2-4 outpatient follow-up visits. You may also be sent smartwatches to wear at home to collect additional data.
