HOw to Reduce Impact Flu

With global anxiety spreading even faster than the new swine flu — and a vaccine still months away — health authorities are struggling to reduce the impact of an outbreak that can't be contained by simply shutting borders.

The world has no vaccine to prevent infection but U.S. health officials aim to have a key ingredient for one ready in early May, the big step that vaccine manufacturers are awaiting. "We're working together at 100 miles an hour to get material that will be useful," Dr. Jesse Goodman, who oversees the Food and Drug Administration's swine flu work, told The Associated Press.

The U.S. is shipping to states not only enough anti-flu medication for 11 million people, but also masks, hospital supplies and flu test kits. President Barack Obama asked Congress for $1.5 billion in emergency funds to help build more drug stockpiles and monitor future cases, as well as help international efforts to avoid a full-fledged pandemic.

Cuba and Argentina banned flights to Mexico, where swine flu is suspected of killing more than 150 people and sickening well over 2,000. In a bit of good news, Mexico's health secretary, Jose Cordova, late Tuesday called the death toll there "more or less stable."

Mexico City, one of the world's largest cities, has taken drastic steps to curb the virus' spread, starting with shutting down schools and on Tuesday expanding closures to gyms and swimming pools and even telling restaurants to limit service to takeout. People who venture out tend to wear masks in hopes of protection.

In New York, the city's health commissioner said "many hundreds" of schoolchildren were ill at a school where some students had confirmed cases.

"Border controls do not work. Authorities sought to keep the crisis in context: Flu deaths are common around the world. Using samples of the flu taken from people who fell ill in Mexico and the U.S., scientists are engineering a strain that could trigger the immune system without causing illness. Vaccine manufacturers are just beginning production for next winter's regular influenza vaccine, which protects against three human flu strains. The WHO wants them to stay with that course for now — it won't call for mass production of a swine flu vaccine unless the outbreak worsens globally. But sometimes new flu strains pop up briefly at the end of one flu season and go away only to re-emerge the next fall, and at the very least there should be a vaccine in time for next winter's flu season, Dr. Anthony Fauci, the National Institutes of Health's infectious diseases chief, said Tuesday.
