...antivirals work? If administered soon after symptoms appear, antivirals Oseltamivir and Zanamivir (brand names Tamiflu and Relenza) are believed to reduce the severity and shorten the duration of the disease by current strain of swine flu. The drugs work by inhibiting an enyzme chemical helper that the flu virus uses to spread from infected human cells to healthy ones. So while not killing the virus, it helps the body fight off the disease by slowing its spread. This, in turn, may help prevent "acute respiratory distress syndrome" - the sudden worsening of flu that, along with secondary lung infections...
...What role can drugs play in tackling a swine flu outbreak? Over the last few years, concern over a bird flu pandemic spurred many governments to stockpile antivirals. While the current swine flu outbreak remains limited in scope, health agencies will likely offer antivirals as a prophylaxis only to those who may have been exposed to the disease: asymptomatic passengers on the same flight as a sick Spanish man, for example, have been given Oseltamivir as a precaution. In New Zealand and Mexico, where there are confirmed cases of the disease, the drug has been made available over-the-counter...
...however, says that so far the virus appears to have stayed relatively stable during the chains of transmission, so it may not be mutating much. Still, the virus's current relatively weak state does not guarantee that it won't return later, much more virulent - which is exactly what happened in the 1918 flu pandemic that killed at least 50 million people worldwide. As the flu season comes to an end in the northern hemisphere, it may lead to a natural petering out of new swine-flu cases in the U.S. But the strain may continue to circulate aggressively...
...Richard Besser, acting director of the Centers for Disease Control and Prevention (CDC), said the agency has begun cultivating the seed stock of virus needed for a swine flu vaccine. (The current seasonal flu vaccine would not be effective against the swine flu.) "We're moving forward aggressively so that if a decision is made that we need to rev up production to make that vaccine, we would be ready to do so," he said.

...antechamber to the restrooms in El Pobre Diablo (The Poor Devil), a bohemian hangout in Quito, the capital. Spoofing the presidential palace's silk screen Yellow Salon, each is marked with the number of days they lasted in office. A digital clock ticks off the days served by current President Rafael Correa. It will probably run far longer than his predecessors...
