This week's question concerns swine flu.

According to a recent report prepared by the President's Council of Advisors on Science and Technology, the H1N1 flu virus, commonly called swine flu, could infect anywhere from 30 to 50 percent of the U.S. population during the fall and winter months. In a worst-case scenario, the virus could cause anywhere from 30,000 to 90,000 fatalities, primarily among children and young adults. Although an H1N1 vaccine is being prepared, it is not expected to be available until mid-October, which some experts say could be too late. So we're curious - are you worried about contracting swine flu?
