Fever Tracking Study

Fever Tracking Study: The Feasibility of Fever Tracking in a Home-setting by a Non-invasive Wearable Core Body Temperature Sensor

The aim of this study is to investigate the feasibility of continuous fever tracking of participants having fever symptoms in a home setting, using a core body temperature (CBT) sensor. CBT as measured by the wearable sensors will be coampared with CBT as measured by ingestible electronc pills (reference).

A secondary research question is, if the CBT behavior of the the participants in a home setting can be compared to previously described CBT profiles in the literature, and if special patterns can be identified.
