Swine Flu: The Second Wave
Federal health officials say swine flu has swept across the nation, with the virus more widespread than ever. Nationwide, visits to doctors for flu symptoms are on a steep incline, with children and pregnant women at particular risk of serious complications.
The mortality rate from the virus is four times higher among American Indians and Alaska Natives than any other racial or ethnic group. Officials blame the discrepancy on crowded living conditions, a higher incidence of complications from pre-existing conditions and poor access to health care facilities.
Experts thought swine flu would kill 1 out of every 100 people who got sick; it's been 1 in 2,000.
November 9, 2009 Some people say they won't get a flu vaccine — against seasonal flu or H1N1 — because they believe it doesn't work. It's true that the seasonal flu vaccine doesn't stop all cases of the flu in people who get it. But just how effective is the new H1N1 vaccine?

President Obama has declared the pandemic a national emergency, but supplies of vaccine against the new H1N1 flu are far below projections. Manufacturers only recently discovered why they can't deliver as much vaccine as expected.

October 23, 2009 The 2009 H1N1 virus has spread across the United States, with millions infected. The virus is mostly causing complications in children and young people. Overall pediatric deaths and hospitalization rates from flu are higher than usual and continue to climb.
October 22, 2009 When more than 100 students at the U.S. Air Force Academy were diagnosed with swine flu, doctors had an opportunity to study the virus closely. They discovered that some cadets who had been symptom-free for more than 24 hours still had the live virus in their noses.
