U.S. swine flu deaths surpass 1,000

Sixty million people have gotten the winter flu vaccine — probably because they're paying more attention to flu warnings in general, thanks to swine flu. It's an unprecedented number of seasonal flu shots for October; most usually aren't given until later in the fall.

Part of it is due to supply: There are already 85 million doses of seasonal flu vaccine available, a much larger amount than usual for this early in the fall. Most years, roughly 100 million doses are used during the season.

But a big factor probably is that swine flu — also known as the 2009 H1N1 virus — is drawing attention to public health warnings that seasonal flu is also a deadly illness than can be prevented through vaccinations, said Joe Quimby, a spokesman for the U.S. Centers for Disease Control and Prevention.

"There's been a heightened awareness in the American public due to H1N1 this year," he said.

Meanwhile, swine flu is more widespread now than it's ever been, and has resulted in more than 1,000 U.S. deaths so far. Flu illnesses are as widespread now as they are at the winter peak of normal flu seasons, said CDC Director Dr. Thomas Frieden.
