It's hardly a joke.

According to the latest news reports, about 1200 over people in mexico have been infected with the swine flu and 152 dead. Just within less than 2 days, the death toll rose from 68 to 152. Can you believe it?
The US, Thailand, Korea, Spain, Hong Kong, New Zealand, have also been affected.
The exact place of origin has not been found yet, though it's within Mexico, that's for sure.
Singapore, being an efficient country, has changed it's health safety zone from green to yellow. And of course, necessary precaution measures have been taken at the airport, in hospitals and schools.
Though the deaths due to swine flu is currently confined to the infected ones in Mexico, it would not be surprising at all when it happens to those in other countries too.
