"Why is it that kids who have never had a medical problem in their lives are suddenly critically ill?" Pelley asked.
"This is one of the really tragic parts of this epidemic. That people who are in the prime of their life, totally healthy can suddenly become so sick. The virus is serious, it can cause overwhelming bacterial pneumonia in some people. The influenza followed by a bacterial pneumonia," she explained.
Asked why the bacteria is following the virus, Schuchat said, "Influenza can damage the respiratory tree's lining and make it easier for bacteria to invade and then the bacteria can cause a pretty overwhelming pneumonia in those circumstances."
H1N1 is a pandemic, meaning it is a global epidemic. It's the first flu pandemic in 41 years.
The federal response looks like a war room, but the officers are in the U.S. public health service, not the military. Their naval rank has been a tradition since the 1790s.
The CDC was first to map the new virus' genetic code. Pathologist Dr. Sherif Zaki showed 60 Minutes lung tissue from patients who died.
"The mortality of H1N1 is something under one percent?" Pelley asked.
"Yes, it's much lower than one percent. But what we're seeing here are those very, very unfortunate times where it is able to kill or cause life threatening disease," Schuchat said.
Dr. Zaki says the amount of virus in these patients is higher than anything he has ever seen in a flu season. "If you imagine all, everything in red here is virus," he explained. "You know, you can see it's lining all those air spaces. You know, we've never really seen this with seasonal influenza."
The rapid growth of the virus is why doctors are recommending many patients take anti-viral drugs at the very first sign of illness.
The 2009 H1N1 strain was discovered in April in California. It is a unique combination of virus genes from birds and humans, but most are virus genes from pigs. That's why some call it swine flu.
The first outbreak was in Mexico. Today, at least 75 percent of the world population lives in areas with the virus and millions have been infected. H1N1 has overwhelmed other viruses, so now it is the dominant flu in the U.S. and in the world.
