Homeland: Travel limited until flu abates

The head of the Homeland Security Department says travel warnings to Mexico will remain in place as long as swine flu is detected.
Secretary Janet Napolitano made the announcement at a news conference Monday. She said the Centers for Disease Control had issued an alert and the State Department's version would be forthcoming.
The virus began in Mexico and had spread to the United States and beyond, with 50 cases reported in the U.S.
Napolitano said she had been in touch with Mexican officials and border state leaders to coordinate responses to the outbreak.
Napolitano urged Americans to use common sense in dealing with the outbreak, such as frequent hand washing and remaining home from work if ill.
