That area (North side of Paris) is interesting and very important, I think.
First that's where CDG airport is. This is the second largest airport in Europe by passenger traffic and the main gateway into Paris for tourists (not least Chinese tourists).
Second, that's where Paris' Gare du Nord is. This is the largest train station in Europe by traffic, where trains from CDG airport arrive, and the start of high speed trains to London, Brussels, Amsterdam.
So to me it's not surprising that this virus arrived there early.
But it also means that the area should be monitored closely, not only by French authorities, but by British ones, etc. as well because any highly contagious disease that shows up there will be around Europe in no time.
