I've just discovered the National Center for Disaster Preparedness at the Mailman School of Public Health in New York City.
At the top of its Press Releases page is a PDF of a November 21 release. A poll taken for the NCDP indicates US public confidence in the government's ability to cope with pandemic flu (among other disasters) has fallen. Katrina and Rita are among the chief causes.
The NCDP is an interesting site. Its emphasis is on natural disasters and bioterrorism, but much of its material seems applicable to pandemic problems as well.
