I can understand how it is more susceptible to death but I don't see the connection with spreading. Old people tend to move about much less and none of the references support that older people are in any way more responsible for spreading the virus. I think much better explanation would be that Italy has a lot of tourism, it is basically a tourism hub for northern and eastern Europe. Tourism == a lot of people moving about, very frequently, then leaving the country. Almost all initial cases here in Poland seem to be connected with somebody coming back from vacation in Italy.
