If you've been diagnosed probable" or "presumed" 2009 H1N1 or "swine flu" in recent months, you may be surprised to know this: odds are you didn't have H1N1 flu. In fact, you probably didn't have flu at all. That's according to state-by-state test results obtained in a three-month-long CBS News investigation. Why the uncertainty about who has and who hasn't had H1N1 flu? In late July, the CDC abruptly advised states to stop testing for H1N1 flu, and stopped counting individual cases. CBS News learned that the decision to stop counting H1N1 flu cases was made so hastily that states weren't given the opportunity to provide input. When CDC did not provide us [CBS News] with the material, we filed a Freedom of Information request with the Department of Health and Human Services (HHS). More than two months later, the request has not been fulfilled. We also asked CDC for state-by-state test results prior to halting of testing and tracking, but CDC was again, initially, unresponsive. We asked all 50 states for their statistics on state lab-confirmed H1N1 prior to the halt of individual testing and counting in July. The vast majority of cases were negative for H1N1 as well as seasonal flu, despite the fact that many states were specifically testing patients deemed to be most likely to have H1N1 flu, based on symptoms and risk factors, such as travel to Mexico. With most cases diagnosed solely on symptoms and risk factors, the H1N1 flu epidemic may seem worse than it is.
