eRouška / eFaceMask

This article has been archived so the contained information may no longer be up to date.

The Ministry of Health of the Czech Republic has decided to suspend the service of the eRouška app from the end of October 2021.

What is the eRouška app for?

The eRouška (meaning eFaceMask) application was created by the “Smart Quarantine” team as one of the tools to get the COVID-19 illness under control and prevent community spread.

How does it work?

The app collects anonymous data about encounters with other eRouška users from Bluetooth in their smartphones. If one of them later tests positive for COVID-19, the app will show the other users an anonymous alert and recommend further steps. The app can tell how close you were to other eRouška users and for what period of time. It knows that an encounter took place, but it doesn't know where.

If you have been infected, you will receive a unique code together with your test results. If you enter this code into eRouška, the app can alert potentially infected users about a risky encounter. Since they will be aware of the fact that they met with someone positive, they will be able to behave more responsibly and protect those in high risk groups.

I got an SMS, telling me I'm positive

If you received a positive PCR test result, read the detailed instructions. If the potentially infected are separated from others in time, this could prevent many more from contracting the illness.

Please, enter the code into eRouška. This information is entered anonymously. Even one code can prevent dozens of people from getting infected.
