The Hack for Sweden hackathon, which the Digitization Authority now supports, usually brings together a few hundred participants to come up with IT-based solutions to various social problems in 48 hours. This year, the focus was the corona crisis, and everything happened remotely. It got more people than ever to sign up.

- It was a fantastic response with over 7,500 dedicated people who came up with very varied proposals, says Madeleine Serenhov, project manager for Hack the Crisis.

From a service that would make people dare to go to stores again using a QR code as an entrance ticket to get their own time slot in the store, to a way to quickly produce a protective visor for healthcare professionals.

The winning concept in the "save societies" category is the Coronafree service that aims to track - not those who have corona - but those who have had it, and become immune.

- If you have antibodies, it is likely that you will not get the disease again, at least not within the next year. And if it is predicted that 60% of Sweden's population will have been infected before this starts to decline properly, then of course you want to know if you yourself belong to these 60 percent or are still in the group that can still be infected , says medical advisor Gunnar Klein, professor of computer science and physician who previously researched immunology.

Certificate of immunity

The idea is that you should be able to go to a doctor's office and do such a test, and if you have the antibodies you should get an "immunity certificate" which can be shown in an app, among other things.

The hope is that it will help to reopen the rebuilt communities, be part of the "exit strategy" that more and more people are beginning to demand.

- You talk about a second, maybe a third wave, and then the only way to try to find the healthy people is if you do not keep being in "lockdown". If you have a certificate that you are immune, you can go back to work or spend time with friends again, says CoronaFree project manager Anders Jonson.
