H1N1 is like a disease that spreads quickly.it refers to flu or grippe.it is a new bacteria in our body that lets us have the disease.if you don't be clean,you will have the disease.

it spreads from one place to another.if you are having the disease influenza A and go near someone the someone will get the disease.that is how it spreads.

Japan,Hong Kong,china and Malaysia have people that have the disease influenza A.

Countries take people temperature.people who are from other countries that are having a fever will be sent back to their country.

I think taking temperature is no use.if you are not clean,you will get the disease too.but it is a little useful too because having a fever can be sent home to rest and will not spread the disease to others.

Singapore has make sure every tourist is not having fever.there will be like a scanner.it tells us is the person is sick or not.

We can wash our hands after,before lunch.wash your hands after using the toilet too.after touching pets,wash our hands too.their fur are dirty no matter how clean you bathe it.the bacteria cannot be seen.
