CHICAGO (Reuters) - Swine flu has killed nearly 10,000 Americans, including 1,100 children and
7,500 younger adults, and infected one in six people in the United States since arriving last April, health
officials said on Thursday.
Dr. Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, said more
than 200,000 Americans had been hospitalized - about the same number who are affected by seasonal
flu in an entire year.
"About 15 percent of the entire country has been infected with H1N1 influenza, or about one in six
people," Frieden told a media briefing.
"That still leaves most people not having been infected and still remaining susceptible to H1N1 influenza,
" he said.
He said supplies of H1N1 vaccine (疫苗) had continued to improve, and some 85 million doses of
the vaccine had been made available for distribution so far, with 12 million more doses added this week.
That is up from 73 million doses a week ago - but still far fewer than had been hoped for by this week.
Even so, Frieden said vaccine supplies had opened up enough that states were beginning to distribute
the vaccine to the general population.
He urged people not to be complacent about (沾沾自喜) getting the vaccine because of reports that
the current wave of H1N1 influenza is decreasing.
"This is still a good window of opportunity to be vaccinated," he said. "Vaccination remains the most
important thing you can do to protect yourself and your family from H1N1 influenza."
He said the seasonal flu season was beginning and it was not clear what would happen with H1N1 or
whether there would be a third wave of the virus in the spring.
"We know that the more people who get vaccinated, the lower the likelihood will be of additional
cases or a third wave," Frieden said.
In a typical year, seasonal influenza kills 36,000 Americans and puts 200,000 into the hospital.
