Just as global markets seem to be recovering from an economic sickness, a biological one looms. “Swine flu,” a type of flu bug transmitted from pigs and mutated into a human strain known as “H1N1,” has so far claimed the lives of over 80 people in Mexico, and sickened more than 1,400 there since April 13. Sunday, the U.S. reported its twentieth case of the flu, including 8 New York-based high school children, and it’s already spread throughout the world to Europe and Asia.
