So far China has not had the same severe outbreaks of H1N1 flu as other countries. This article explains why.
When we came back to China from Hong Kong, we all had to fill out health forms asking about flu symptoms and everybody's temperature was taken. If you had a high temperature, I guess you got to go get tested for the flu, and quarantined if you had it. This was also the case when we entered the country last summer.
At the beginning of the school year, our school was closed the first Friday afternoon because some kids had the flu. When I reported a classroom with several coughing kids I was told they didn't have the flu since they had already been checked, and that all the classes got their temperatures taken each morning.
They are really all over it. Heck, the US didn't even have a Surgeon General until Oct 29 thanks to some chickenshit politicking by Mike Enzi and others. Way to put the health of the nation first, guys!
