With the cable news networks reporting nonstop on swine flu, it feels like the disease is lurking everywhere, and that your slightest sniffle is a sign that you've contracted the virus. That would explain why people with no outward symptoms of illness are flooding emergency rooms in swine fluaffected states, afraid that they might be sick. That's a really bad idea.
First of all, having to examine people who aren't really sick only stresses the already strained resources of hospitals that are trying to prepare for a pandemic. Plus, going to an emergency room unnecessarily may even pose a slight risk to you. In past outbreaks, including SARS in 2003, hospitals were actually loci of infections all those sick people in close proximity and the same could be true of swine flu.
If you actually have flu-like symptoms a fever above 100° F, headache, sore throat, body aches, chills or fatigue and you live in an area where there have been confirmed swine flu cases, by all means report to your doctor. Otherwise, leave the hospital to the sick people.
