Government officials have declared a public health emergency in connection with the swine flu outbreak that has killed dozens in Mexico and sickened 20 in the U.S., said the nation’s director of Homeland Security Sunday.
Secretary Janet Napolitano also said border agents have been directed to begin passive surveillance of travelers from affected countries, with instructions to isolate anyone who appears actively ill with suspected influenza.
The number of cases confirmed in the United States by the federal Centers for Disease Control and Prevention is now 20, including eight New York City high school students. Other cases are in Ohio, California, Texas and Kansas. Patients have ranged in age from 7 to 54.
Government health officials expect to see more cases of swine flu here, including possibly serious infections, a senior CDC official said.
