How many people have swine flu?
That’s no longer possible to answer, because so many people have become infected that most nations can no longer test everyone suspected of having H1N1 swine flu. The CDC counts hospitalizations and deaths. But instead of misleading case counts, the CDC offers a map showing where flu is widespread and charts showing whether unusual numbers of people are showing up in doctors’ offices with flu-like symptoms and whether there are unusually high numbers of deaths from pneumonia and influenza.
