While swine flu itself is probably still around, it's the old case that the media has gotten bored of it, the novelty has just worn off. The newspapers and new programmes on tv will only ever stick with a story until another one comes along that's worth following even more.
So, here in the UK, swin flu was only headline news until the expenses scandal kicked off. Once that had begun, all I saw of swin flu was at the end of one news show, they quickly said "in other news, there are another 8 confirmed cases of swine flu in the UK".
Anyway, who wants to take guesses on what the next brand-name "flu" will be? Personally, my money's on Piscine Flu. Fish seems like the obvious choice and to make it as unsettling as possible, they will have to go for an all encompassing term.
