The new H1N1 flu virus appears to be fairly widespread in the United States and seems to be hitting mostly younger people, with very few cases reported in people over 50, U.S. health officials said on Sunday.
"We think very few of the cases we have confirmed are in people over 50," the U.S. Centers for Disease Control and Prevention’s Dr Anne Schuchat told reporters in a telephone briefing. "Whether this will pan out over the weeks ahead we don’t know."
The CDC reported 226 cases of the new H1N1 swine flu virus and one death in 30 states. The CDC previously had confirmed 160 cases in 21 states.
