The World Health Organization declared the first influenza pandemic in more than 40 years, due to the spread of the H1N1 swine flu.

WHO has raised the pandemic flu alert into six,the highest one which means the disease is spreading world-wide.

However,the fact is the virus seems like quite moderate at the moment and so people are not necessary to be too worry about it.The only thing we need to remember is to maintain good personal hygiene including frequent hand-washing.

As medicines have been well-prepared and we have experience to successfully get rid of SARS,I believe we finally could overcome this difficulty too.

Human beings are smarter than the virus,aren’t we?
