I was surprised also, but when looking at trace of where our first case came from the numbers told a clear story. A lot of work was done here at first to track those infected and who they got in contact with, so that is also why it is know where they got it):
Italy: 62 (may have been 58 or 64, but no more and no less)
With things being so bad in Italy I thought that it would have been all Italy, but it turns out that with the way the Austrians kept their skiing resorts open despite knowing there was trouble a lot of people from all over got infected there.
On the same time 1 Dane picked up the virus in Germany, he was in contact with an Italian at that conference
