If we see what is happening in Europe at this moment, I think we have to be worried. We see dead swans and we know that swans are highly susceptible [to H5N1]. And they share their ponds, the places where they swim, with other birds as well that are less susceptible, for instance ducks. And they might have actually infected the swans, so I think we have to be prepared in Europe, especially since the bird migration is about to start.  -   Albert Osterhaus     Quotes
