In response to the growing spread of swine flu across the globe, the World Health Organization has raised its alert level to 5, indicating it believes a pandemic is "imminent." But as [the American Council on Science and Health]'s Dr. Elizabeth Whelan says, "We need to put this situation in perspective by remembering that the U.S. has over 30,000 deaths every year from seasonal influenza."…
As the epicenter of the outbreak, Mexico is right to take precautions like ordering the closure of many public services and private businesses until Tuesday. But many other countries are taking drastic and unnecessary steps in the name of "protecting" their citizens. Egypt has ordered that the country's 300,000 pigs slaughtered, even though swine flu has not appeared there and there is no evidence that pigs spread the disease. Many nations have (unnecessarily) restricted the imports of pork products and live pigs, while others are imposing bans on travel to Mexico. "But in the U.S., closing the borders would be like closing the barn doors after the horse got out, as President Obama has aptly expressed," ACSH's Dr. Gilbert Ross reminds us.
Folks in the U.S. should take a deep (maskless?) breath and relax.
