The "worst-case scenario? We are ready". That is in a few words Silvio Brusaferro statement, the president of Iss (the italian Istituto superiore di Sanità), interviewed on the radio broadcast Un giorno da pecora, on Rai Radio 1. Referring to the words of Tedros Adhanom, Brusaferro says: ""The spirit expressed by the WHO Director-General is that of maximum prudence and of preparing for even the worst scenarios, hoping that they will never occur. We are ready". Brusaferro, then, agrees that the contagions between people who have never been to China could be only "the tip of the iceberg".
