I think its clear as day at the moment; When you allow people over the world to travel again and the checks are very very very poor ... Then you instant will see increase in covid-19 infected people.
I also see it now in The Netherlands ... The numbers are getting up again and I fear the worst if there arent any actions/measures taken by the government soon ...
I think people should STOP traveling for a while; specially when its just for fun ... We first need to have THE cure or whatever for this nasty virus!
