Summary
On June 11, 2009, in response to the global spread of a new strain of H1N1 influenza ("flu"), the World Health Organization (WHO) declared the outbreak to be an influenza pandemic, the first since 1968. WHO said that the pandemic declaration was based on the geographic spread of the new virus, not on increasing severity of the illnesses it causes. Officials now believe the outbreak began in Mexico in March, or perhaps earlier. The novel "H1N1 swine flu" was first identified in California in late April. Health officials quickly linked the new virus to many of the illnesses in Mexico. Since then, cases have been reported around the world. When the outbreak began in late April, U.S. federal agencies adopted a response posture under the overall coordination of the Secretary of Homeland Security. Among other things, officials established a government-wide informational website (http://www.flu.gov), released antiviral drugs from the national stockpile, developed and released diagnostic tests for the H1N1 virus, and developed guidance for the clinical management of patients and the management of community and school outbreaks. The Obama Administration requested about $9 billion in emergency supplemental appropriations to address the situation. On June 26, the President signed P.L. 111- 32, the Supplemental Appropriations Act, 2009, which provided $1.9 billion immediately, and an additional $5.8 billion contingent upon a presidential request documenting the need for, and proposed use of, the additional funds. U.S. health officials have procured millions of doses of pandemic flu vaccine, and have begun a voluntary nationwide vaccination program. It is being coordinated by state health officials and carried out through public clinics, private health care providers, schools, and others. The Secretary of Health and Human Services has implemented waivers of liability and an injury compensation program in the event of unforeseen vaccine safety problems. Allocation schemes have been developed to give priority for limited vaccine doses to high-risk groups. This report first provides a synopsis of key events, actions taken, and authorities invoked by WHO, the U.S. federal government, and state and local governments. It then discusses the WHO process to determine the phase of a flu pandemic, selected activities by the Departments of Homeland Security and Health and Human Services, and selected activities by state and local authorities. Next, it lists congressional hearings held to date, and provides information about appropriations and funding for pandemic flu activities. Finally, it summarizes U.S. government pandemic flu planning documents and lists sources for additional information about the situation. This report will be continually updated to reflect unfolding events.
