I don't know about severity, but Norway is the European country with the highest infection ratio, after Italy and tiny Iceland. As of today:
- Italy: 1 case per 3.996 inhabitants - Iceland: 1/4.285 - Norway: 1/6.710 - Denmark: 1/9.081 - Switzerland: 1/10.035 - Spain: 1/14.831 - France: 1/23.292 - Germany: 1/30.160
