It’s deadly serious; so even if the current threat fades, the world needs to be better armed

IT IS said that no battle-plan survives contact with the enemy. This was certainly true of the plan drawn up over the past few years to combat an influenza pandemic. The generals of global health assumed that the enemy would be avian flu, probably passed from hens to humans, and that it would strike first in southern China or South-East Asia. In fact, the flu started in an unknown pig, and the attack came in Mexico, not Asia.
The hens, though, deserve some credit. The world has not had a pandemic (a global epidemic) of influenza since 1968. Four decades are long enough to forget that something is dangerous, and people might have done so had they not spent the past ten years considering the possibility that a form of bird flu which emerged in Hong Kong in 1997 might be one mutation away from going worldwide.
The new was raised on April 29th to just one notch below the level of a certified pandemic by the World Health Organisation. In an effort to halt(parar) the spread of the disease, Mexico’s president, Felipe Calderón, has announced that non-essential services should close down between May 1st and 5th, and people should stay at home. Part of the reason for worry is that, unlike ordinary flu, which mostly carries off the old, the victims of this disease are mostly young and otherwise healthy.
Still, this epidemic has not actually killed many people yet. That there have been a mere handful of confirmed deaths is probably the result of a lack of proper tests. But even if all the possibles are counted in, a couple of hundred fatalities cannot compare with the 30,000 deaths caused in America each year by seasonal influenza. So how scared should we be?
