President Obama has declared swine flu a national emergency. The emergency declaration allows the Secretary of Health and Human Services to waive federal rules for hospitals, permitting them to set up alternate treatment sites for H1N1 patients, such as schools, community centers or even tents. Demand for the H1N1 vaccine continues to outstrip supply. Nationwide, only 11 million doses have been distributed, not the 120 million federal health officials had expected to have by now.
