- There will be large variations in how different countries handle this, but if you have had a "lockdown" there is a risk that the spread of infection will pick up speed again.

Few want to shut down completely again and try with other types of recommendations that can be more effective in the long term, says epidemiologist Emma Frans in SVT's Morgonstudion.
