WASHINGTON (CNN) — The federal government declared a public health emergency Sunday as the number of identified cases of swine flu in the United States rose to twenty.
The declaration is part of a “standard operating procedure” that will free up additional government resources to combat the virus, Homeland Security Secretary Janet Napolitano said at the White House. Additional cases of swine flu are expected to be reported in the coming days, added Dr. Richard Besser, the head of the Centers for Disease Control and Prevention.
The declaration came as the World Health Organization (WHO) advised all countries to be on the lookout for “unusual” outbreaks of flu, following an emergency meeting Saturday as the seriousness of the outbreak became clear.
