Ask Eric Weaver about pandemics, and he s quick to remind you of a fact that illustrates the fleeting nature of human memory and the proximal nature of human attention: The first pandemic of the 21st century struck not in 2019, but 2009.
That s when the H1N1/09 swine flu emerged, eventually infecting upwards of 1.4 billion people nearly one of every five on the planet at the time. True to the name, swine flus jump to humans from pigs. It s a phenomenon that has been documented more than 400 times since the mid-2000s in the United States alone.
