Twenty-two students and three teachers in New Zealand, who returned from a three-week-long language trip to Mexico, may have been infected with the swine flu virus, officials said Sunday.
The suspected infections in New Zealand follow reports that a deadly new strain of the virus cropped up more places in the United States and Mexico Saturday.
The World Health Organization calls this "a public health emergency of international concern."
