Although there is no vaccine to fight the virus so far, the centre said swine flu was "preventable, controllable and treatable."
Notices have been posted at airports across the country advising people who return from disease affected regions to report flu like symptoms at the point of entry.
Walk-through thermal scans have been activated to detect travellers with a high fever.
A series of tough measures has also been announced in Hong Kong, where the Sars virus (Severe Acute Respiratory Syndrome) killed hundreds of people in 2003.
China, with its massive population and large communities living in close proximity to farm animals, is one of the most susceptible to large outbreaks of diseases. It's good to hear that they are going through all the proper precautions.
At the same time, it is disappointing to see the usual lackluster response from the US. Despite our "advanced" economy and "streamlined" DHS, the reaction in a place that is already quickly being overrun by the virus is pathetic.
EL PASO, Texas (AP) -- U.S. airports and border agents waved people through Monday with little or no additional screening for Mexico's deadly swine flu - a far more muted reaction than the extreme caution elsewhere around the world.
But the American reaction to swine flu, which has killed up to 149 people in Mexico and on Monday led the World Health Organization to raise its alert level, was mostly limited to steps that hospitals, schools and mask-wearing individuals took on their own.
At the main pedestrian border crossing between El Paso and Mexico's Ciudad Juarez, a handful of people wore protective masks and officials handed out a swine flu flier provided by the Centers for Disease Control and Prevention.
But there were no extra screenings for swine flu, and it mostly looked like a typical day at the border. Suddenly faced with a new and unforeseen threat, people entering the country who said they felt unwell were questioned about their symptoms. But there were no reports of anyone refused entry.
Just a typical day at the border I guess. No wonder so many drugs can easily get into our country, we couldn't care less what's crossing the border, whether it be narcotics, gang members, or a potentially existential virus.
