MEXICO CITY – The schools and museums are closed. Sold-out games between Mexico's most popular soccer teams are being played in empty stadiums. Health workers are ordering sickly passengers off subways and buses. And while bars and nightclubs filled up as usual, even some teenagers were dancing with surgical masks on.
Across this overcrowded capital of 20 million people, Mexicans are reacting with fatalism and confusion, anger and mounting fear at the idea that their city may be ground zero for a global epidemic of a new kind of flu — a strange mix of human, pig and bird viruses that has epidemiologists deeply concerned.
Tests show 20 people in Mexico have died of the new swine flu strain, and that 48 other deaths were probably due to the same strain. The caseload of those sickened has grown to 1,004 nationwide, Mexico's Health Secretary Jose Angel Cordova said.
The same virus also sickened at least eight people in Texas and California, though there have been no deaths north of the border, puzzling experts at the U.S. Centers for Disease Control and Prevention.
Scientists have warned for years about the potential for a pandemic from viruses that mix genetic material from humans and animals. This outbreak is particularly worrisome because deaths have happened in at least four different regions of Mexico, and because the victims have not been vulnerable infants and elderly.
The most notorious flu pandemic, thought to have killed at least 40 million people worldwide in 1918-19, also first struck otherwise healthy young adults. -snip-
No vaccine specifically protects against swine flu, and it is unclear how much protection current human flu vaccines might offer.
A "seed stock" genetically matched to the new swine flu virus has been created by the CDC, said Dr. Richard Besser, the agency's acting director. If the government decides vaccine production is necessary, manufacturers would need that stock to get started. Actually producing the vaccines could take months.
The CDC says two flu drugs, Tamiflu and Relenza, seem effective against the new strain. Roche, the maker of Tamiflu, said the company is prepared to immediately deploy a stockpile of the drug if requested. Both drugs must be taken early, within a few days of the onset of symptoms, to be most effective.
Cordova said Mexico has enough Tamiflu to treat 1 million people — only one in 20 people in greater Mexico City alone — and that the medicine will be strictly controlled and handed out only by doctors.
