If a pandemic strikes the U.S., it will kill about 1.7 million people, hospitalize 9 million, exhaust antiviral medications and reduce basic food supplies, according to a planning scenario developed by financial service firms preparing for such a catastrophe.

A U.S. pandemic would exhaust antiviral medications, reduce basic food supplies, put ATMs out of service, shut down call centers, increase gas prices and up health insurance claims by 20 percent, according a test project developed by financial service firms.
