Strange?

So all of Hong Kong's primary and kindergarten schools have closed - giving the children a couple of extra weeks off and the parents the joy of yet more time to fill. More time for the children to forget everything they've learnt this year, and more hours to get bored and fractious.

Actually, I have no problem with the schools closing. The government said that if students got sick all schools would close and they've been as good as their word. What strikes me a slightly strange is the trigger for this closure...

Twelve secondary school students have been diagnosed with H1N1 piggy flu!

(Yeah, yeah - I know. The school at which the twelve older students were diagnosed has also been closed, and this is a precautionary measure to protect the [usually more vulnerable - but maybe not with this strain of flu] younger children. I just found it vaguely amusing)
