Once installed, the mobile phone indicates its presence to all nearby devices using random identifiers, not disclosing any personal information. The information shared between devices allows STAYAWAY COVID to know the mobile phones one has been close to, how close and for how long. The World Health Organisation considers that an exposure within 2 meters and longer than 15 minutes to someone with COVID-19 presents a high contagion risk.
1. No high-risk contacts
If the app does not detect any high-risk contacts with someone diagnosed with COVID-19 then it displays that exact message and the date of the latest evaluation.
2. Exposure notification
If, in the last 14 days, we have been exposed to someone with COVID-19 and that has shared this information with the STAYAWAY COVID system, then the app will promptly notify us so that we can isolate ourselves and call Linha SNS 24 (808 24 24 24).
3. If tested positive to COVID-19
Should we test positive to COVID-19, along with the diagnosis we will receive a numeric code allowing us to share, anonymously and through the app, this information with the STAYAWAY COVID system. It is this important step that enables the app to timely alert all those that have been exposed to our contagion, even before displaying any symptoms. No identity is ever disclosed to anyone.
The STAYAWAY COVID APP has been developed by INESC TEC, ISPUP, Keyruptive and Ubirider for the Directorate-General for Health / Ministry of Health.
