The World Health Organization has called for an unprecedented summit of flu vaccine makers to deal with a possible flu pandemic.
In 1918 the flu killed tens of millions of people. The outbreak of the bird flu early this year and it's increasing presence in Asia, have at least one official with the UN Health Agency worried that it's just a matter of time before such a virus adapts itself to spread more easily from person-to-person, and cause a severe worldwide outbreak.
Unlike the flu pandemic of 1918, we now have antibiotics that can fight off secondary bacterial infections like pneumonia. And anti-viral drugs can also shorten the duration of the flu itself, if taken within four days of the onset of symptoms.
