H1N1 in Singapore (jangan parno dengan flu babi !)

A week ago i just got back from singapore, surprisingly when there's big news here and there by media about H1N1 when i pass the immigration last time in May 2009 they put the heat scanner to scan the body temperature at Changi airport... when i went there a week ago its not there anymore.Not much other passengers wearing mask, and inside the city it self for 3 days i rarely see people there
