The 'open borders' is within EU countries -- not with non-EU countries.
So if you go from China to the EU, you need to go through border control. But if you are a British citizen, you don't need to go through border control at Copenhagen, for instance
The rest of the article is known -- Milan has thousands of Chinese workers in its textile industry and they, coming back after chinese new year celebrations brought the coronavirus
however:
1. The virus then spread because Milan has a number of old people
2. when the Italian government told children to not go to school, they took the opportunity to go to discos, congregate etc. spreading the virus
the dead are mostly old "white" folks
“Milan has thousands of Chinese workers in its textile industry” interesting, regular economics would suggest that bringing in Poles, Hungarians, Bulgarians etc. would have made more sense. But then, who said these were “workers” rather than indentured servants?
It seems pretty obvious at this point that it is the “old” folks who need to be quarantined off until the young-in’s herd immunity is reached and a vaccine or two developed.
>>the dead are mostly old “white” folks<<

What about the Afro-Italians?
