Finland COVID-19 Mobile Application
Koronavilkku is a contact tracing app produced by the Finnish Institute for Health and Welfare (THL) to help you find out whether you may have been exposed to coronavirus. If you have a coronavirus test and are diagnosed as infected, you can use the app to share this anonymously with those you have been in close contact with.
How Koronavilkku app works?
Download the free Koronavilkku app from an app store (Apple App Store and Google Play). The app works automatically in the background without affecting phone use or draining the battery.
The phones of Koronavilkku app users send a randomly generated code to each other when they come into close contact. The phone stores anonymous information about the contact.
If you have been close to someone who reports that they have been taken ill, you will receive an alert of potential exposure. If you have been diagnosed with coronavirus, the health service will send you a key code. When you tap this code into the app, you anonymously alert other Koronavilkku app users who have been close to you of potential exposure.
Feature of Koronavilkku app
First. The phone receives a randomly generated code
The app assigns a random code to each phone. The code contains no information about you or your phone.
Second. Phones swap codes with each other
When close enough to each other, the apps swap codes through a Bluetooth signal. User identity or location is not saved. The app retains the codes for 21 days before automatically deleting them.
Third. When someone reports their infection
When a user reports their infection to the app, the app sends the codes it has collected to a server. If you have been in close contact with a code downloaded to the server, the app will send you an alert of potential exposure.
Fourth.You receive an alert of potential exposure
If you receive an alert of potential exposure, the app will give you further instructions on what to do. The Koronavilkku app can also be used to make a symptom assessment through the Omaolo health check service.
Fifth. If you are diagnosed with infection
If you have tested positive for coronavirus, a healthcare professional will give you a key code. When you tap this code into the Koronavilkku app, your app sends the codes it has collected to the server. Anyone you have been in close contact with will then be alerted of potential exposure. Since no personal data or information about whereabouts is sent with the codes, you cannot be linked to any potential infection.
