Since the Middle Ages, the great plagues have frightened us. We see the loss of large segments to something that is invisible to the naked eye, and some how linked up to animals and diseased carriers. Our responses are really often the same: fresh air, isolation, and prayer. So it was with the bird flu, with AIDS, and now with swine flu, except now we are more international, more porous, and thus more vulnerable.
The Hall Institute prints here the CDC link which is probably the very best information and the most current that we possess. The address is: http://www.cdc.gov/swineflu/
