A White House document, titled National Strategy for Pandemic Influenza (NSPI) says so, "A pandemic, or worldwide outbreak of a new flu virus, could overwhelm our health and medical capabilities, potentially leading to thousands and thousands of deaths, millions of hospitalizations and hundreds of billions of dollars in direct and indirect costs."

At current levels of international human traffic, a localized outbreak can escalate into a worldwide pandemic. Then a lock or solitude zone has to be generated wherein food and human products from contaminated areas are not permitted to be transported across countries.
The preventative measures at the time of today consist mostly of advisories and tips to be followed by people and authorities across the risk likely countries. Amazingly rapid advances in the area of genetics and pharmaceuticals are being forced to think of a foolproof plan for the development and installation of vaccines against bird flu.
