eRouska (eFacemask) is an app for mobile phones that has been developed to use bluetooth to track all users of the app with whom you come into contact with.

The eRouška application is available for operating systems Android (download here) and iOS (it should be released for iPhone in the next few upcoming hours/days) and it’s based on the Bluetooth technology.

Once the users give their permission to the app, phones with activated Bluetooth service can let one another know when they meet. The eRouška application then saves anonymized data into the owner’s phone about mobile devices with the same application which were recently in its vicinity.

If a user’s coronavirus test comes back positive, the phone data can then be used to send anonymized identification numbers of other applications to health officers during an epidemiologic investigation. If once again the user gives permission, only authorized health officers will be able to pair individual identification numbers with phone numbers entered during the registration and then contact potentially infected citizens.

The eRouška application, which the Ministry of Health has taken under its patronage should facilitate an easier, faster, and more effective process of looking up people who are at high risk of infection due to contact with an infected person.
