Ive a mate with a second house in Italy (Naples region out in the sticks and up a mountainside), and he went there in Feb (2 weeks), and his sure he picked it up there cos when he came back he was 'flu like' for 3or 4 days.
he says Italy has been hit hard because they do that kissie / kissie thing on each cheek - plus millions of tourists from all over the world who go around kissing statues one after another - many over the retirement ages and devoutly religious - and elderly. - its only his view mind, nothing scientific..
