WASHINGTON (CNN) - Secretary of State Hillary Clinton Monday said the State Department is working with both domestic and international agencies to combat swine flu.
She said the State Department is "urging caution" for Americans considering travel.
"We have put up on our Web site information urging caution for those who are planning to travel," Clinton said at a photo-taking session at the State Department Monday morning.
So far the State Department has not issued a specific travel warning for Mexico or elsewhere.
She said the State Department was coordinating "very closely" with other federal agencies including the Centers for Disease Control and Prevention and the Department of Homeland Security.
"We are taking this very seriously and working also with the World Health Organization … to try to develop a strategy to prevent the spread of this form of swine flu. We do believe that our efforts are developed and prepared to confront this wherever it might occur inside our own country. And enhanced cooperation across boundaries will be very important," Clinton said.
And she said the U.S. had offered help and assistance to the government of Mexico to make sure they have the resources and the technical expertise they might need.
Earlier, the State Department said it had sent a cable to all posts worldwide urging employees to be on the lookout for swine flu symptoms among
their colleagues and family and to take precautions to prevent catching the
flu, officials said.
The cable, dispatched Sunday, encouraged the posts to review guidelines for a pandemic, as a precautionary measure, officials said. Those guidelines were updated recently with the worldwide outbreak of avian flu.
The U.S. Embassy in Mexico City has suspended non-emergency services through Thursday due to the outbreak of swine flu, the State Department said on its Web site Monday.
In a warden message sent to American citizens, the embassy said it was taking the measure in accordance with measures announced by the City of Mexico to limit the congregation of large crowds" through April 30. The embassy is closed for a holiday on Friday.
Visas will not be issued and only Americans with extenuating circumstances will be permitted in the embassy, the advisory said.
These are precautionary measures only, taken to best assure the well-being of our clients and staff, the advisory said.
