The growing influenza activity across North America this winter certainly feels bad — especially to those that have been hit by it. But it's nothing compared with the "flu pandemic that is almost certainly on the horizon if we don't dedicate energy and resources to a universal vaccine," write Michael T. Osterholm and Mark Olshaker in The New York Times. "Influenza pandemics occur when a novel animal flu virus acquires the ability to infect humans and they, in turn, transmit it to other humans. The 1918-19 Spanish flu epidemic (which despite the name may have originated in the American Midwest) killed 50 million to 100 million around the globe. Accounts at the time described people falling ill in the morning and dying that night. "Given the century of medical progress since then, one might conclude that we are far better prepared today to deal with such a worldwide catastrophe. Unfortunately, the opposite is true. "The world has about four times the number of inhabitants it did in 1918, including hundreds of millions of people, poultry and pigs living close together. This provides a potent biologic mixing bowl and natural influenza virus mutation factory. What's more, nearly any point on the planet is accessible to any other point within hours, and there are more than a billion international border crossings each year. The virus will spread rapidly." |
