The reality of the security placed upon the H1N1 flu in Singapore did not become real to me until my visit to the hospital.
Queuing up to enter the hospital.
Mention your purpose to the hospital.
Then give ya IC, they'll scan it.

Empty waiting room at the Pharmacy

Thermo scanner in the hospital after you step in
See the (blur) red circle to the top left
Two guys stationed there. I think they students on holiday or waiting to enter university.
I think they get paid damn well (for the risk that they are taking)

Nonetheless, things are under control in Singapore. No worries, for now. :)
