Digital Contact Tracing Tools for COVID-19
Digital contact tracing tools vary in purpose, features, and complexity, but they can add value to
traditional contact tracing efforts by:
Improving the efficiency and accuracy of data management and automating tasks;
Reducing the burden of data collection on public health staff by allowing electronic self-reporting
by cases and contacts;
Using location data to identify community contacts unknown to the case to look at
possible exposure.
Public health staff may have different contact tracing challenges, making a one-size-fits-all solution
unlikely. Below are some items to consider when selecting the best tool for contact tracing.
