Federal health officials say this year's flu season shaping up to be especially severe for the elderly.

According to the latest update from the federal Centers for Disease Control and Prevention, the number of people age 65 and older who are getting the flu jumped sharply in the last week or so. They are being hospitalized at a rate of about 82 per 100,000 cases. That's the rate that is seen during severe seasons, officials said.

Federal healthy officials said Friday there are some early signs this year's flu season may be easing in some parts of the country. But they stressed it's far too early to tell whether the flu season has peaked.

The number of states reporting widespread flu activity is up to 47, according to the Centers for Disease Control and Prevention. But flu activity nationally fell slightly in the CDC's most recent data. Five states reported less flu than a week earlier, according to the CDC.

The Food and Drug Administration announced Thursday that it was requiring companies that make Ambien and similar sleeping pills to sharply cut the doses of the drugs.

This year's flu season started about a month early, prompting federal health officials to warn it could be one of the worst in years. They're urging everyone to get their flu shots.

But like every flu season, there are lots of reports of people complaining that they got their shot but still got the flu. What's up with that?

Well, as Michael Jhung of the Centers for Disease Control and Prevention explains, there are lots of possible reasons.

Katie Alonzo was stunned when doctors told her they couldn't get a drug her 10-year-old daughter, Abby, was taking to fight lymphoma.

"When a doctor says, 'This is what you need to take.' And then all of a sudden somebody tells you, 'Well, that is what you need to take but this isn't available so we're going to try this instead,' it's very scary," say Alonzo, who lives in Port St. Lucie, Fla.

We all know that nobody's perfect. But now scientists have documented that fact on a genetic level.

Researchers discovered that normal, healthy people are walking around with a surprisingly large number of mutations in their genes.

It's been well known that everyone has flaws in their DNA, though, for the most part, the defects are harmless. It's been less clear, however, just how many mistakes are lurking in someone's genes.

When Christine Rowan gave birth prematurely in August, her new baby was having problems breathing. So Rowan brought her daughter, Zoe, to the Children's National Medical Center in Washington, D.C., for genetic testing.

"It's funny because when we first had the testing done, we didn't even really think about the fact the testing was going to lay out all of her DNA," says Rowan, 32, who lives in Northern Virginia.

But while Rowan and her husband were waiting for the results, questions started popping into their heads.
