SEOUL AND MADRID — Reaction to the spread of swine flu may seem muted in the United States, despite its proximity to the deadly outbreak in Mexico.
But that's not the case in Asia, Western Europe and the Middle East, where the threat of a pandemic has quickly led people to don protective masks and officials to screen tourists, ban meat imports and advise against travel to the Americas.
The responses follow a series of microbial scares in recent years that include avian flu, severe acute respiratory syndrome, or SARS, and mad cow disease.
The tactics in Asia, which include high-tech screening of airline passengers for fever, new quarantine facilities, heightened public vigilance and a scurry for scientific research, come straight from a playbook devised during the SARS and avian flu crises.
SARS killed about 800 people, mostly in mainland China and Hong Kong, in 2003. Avian flu has killed 257 worldwide since 2003. From Japan to Malaysia, officials are taking no chances, and residents are donning protective masks.
"SARS frightened the world, but the place it frightened most was Asia -- Hong Kong, China, Vietnam," said Peter Cordingley, a spokesman for the World Health Organization's office in Manila. "The lessons Asia learned from SARS are still around as the world faces this new virus."
The anxiety level also runs high in other regions.
In Spain, where at least 30 possible swine flu cases have been reported, teams of doctors and police officers wearing masks and surgical gowns boarded arriving planes, distributed forms for contact information and advised passengers to seek treatment if they experienced symptoms.
And in Egypt, which is struggling with bird flu, the Health Ministry ordered the slaughter of the country's estimated 300,000 pigs.
The farther away from Mexico, it seems, the quicker nations have erected defenses.
France, where 20 suspected cases are under study, has amassed enough doses of Tamiflu, an anti-influenza drug, to cover half the population of 60 million.
British Prime Minister Gordon Brown told Parliament that the number of doses of antiviral drugs available to the public would be increased from 33 million to 50 million.
Russia has banned meat imports from California, Texas and Kansas, and China has banned the import of pork from the three states plus Mexico, despite a lack of evidence that swine flu can be transmitted through meat.
