A whole primary school class in Geneva has been quarantined after the discovery of a probable case of the omicron variant.
One class at the De-Livron school in Meyrin has been told to isolate, that also includes the staff and parents.
Everyone will have to take a test which will be checked for the highly contagious variant.
There have only been a few confirmed cases of omicron, but it does take a week to sequence the tests for the new variant.
