A total of 20 swine flu cases have been confirmed in the United States, acting director of the Centers for Disease Control and Prevention Richard Besser said Sunday, Xinhua reported.
The 20 cases confirmed so far are in New York, Ohio, Kansas, Texas and California, Besser told a White House briefing. He also expected more cases and more severe illness among Americans.
Besser says things are moving fast and that authorities expect the virus to spread. But he assured Americans that health officials are taking action to minimize its impact.
