Momentarily Risking Schengen's Ideal Over Fears of a Coronavirus-Affected European Economy

We've seen how Italy is propagating the coronavirus inside Europe, there are cases in Austria, Switzerland, and more cases in France (via Italy) and Spain, in Barcelona and Tenerife. Still, Schengen border closures have been ruled out by the EU. I would rather say that the Italian border could be closed for the time being, based on the following arguments. First, patient zero in Italy hasn't been located consequently there is no known transmission route. Second, Italy is not a bastion in the European economy. Europe could be most affected by the spread of the coronavirus to the engine and heart of its economy than by the closure of borders with Italy. Since the containment in Italy is failing, the safest option would be to close borders.
