Dear donors, since the middle of December, we have seen a significant decrease in the number of confirmed COVID-19 cases in Germany until the end of February. However, until now the Fever Monitor has continued to deviate from the case counts starting around the beginning of the new year. In this post, we will try to explain why we think this happened and introduce to you our updated algorithm.
The Corona Data Donation Project is designed to detect fever symptoms in the time-series of the donors’ daily resting heart rate and daily step count signals. See blog post “How does it work?” for the mechanics of how the whole thing works and the basic idea behind it, or check out some of the preliminary results we obtained in the past.
