画像 【ワシントン=勝田敏彦】米疾病対策センター(CDC)のフリーデン所長は10日の記者会見で、米国での新型の豚インフルエンザの死者が約1万人に達したと発表した。高齢者の死亡が多い季節性インフルエンザと異なり、死者のうち17歳までの子どもが約1100人、18〜64歳が7500人を占めた。
 今回の発表は4月以降11月14日までの推定で、CDCは、米国民の6人に1人にあたる5千万人が発病したとみている。
 所長は「インフルエンザの勢いは弱ってきている」と述べたが、ウイルスが変異する可能性もあるため、「今後は予測しにくい」としている。

 【ワシントン=山田哲朗】米疾病対策センター(CDC)のトーマス・フリーデン所長は10日、米国の新型インフルエンザ患者数の推計値を発表した。
 4月の発生から11月14日までの間、患者は4700万人で、人口の約6分の1に上った。
 このうち21万人が入院し、9800人が死亡したとみられる。死者のうち1000人が17歳以下で、季節性インフルエンザに比べて若年層の重症化が目立つ。
 北米では新たな患者の発生が減り続け、秋に始まった感染の第2波はピークを越えたとみられている。
 しかし、フリーデン所長は「第3波が来るのか来ないのかは予測できない」と述べ、予防接種を受けるよう、引き続き呼びかけた。
 米国では、毎年3万〜4万人が季節性インフルエンザで死亡している。

CDC Estimates of 2009 H1N1 Influenza Cases, Hospitalizations and Deaths in the United States, April -- November 14, 2009
http://www.cdc.gov/h1n1flu/estimates_2009_h1n1.htm

Updated Estimates from April -- November 14, 2009

Using the same methodology CDC has updated the estimates to include the time period from April through November 14, 2009.

* CDC estimates that between 34 million and 67 million cases of 2009 H1N1 occurred between April and November 14, 2009. The mid-level in this range is about 47 million people infected with 2009 H1N1.
* CDC estimates that between about 154,000 and 303,000 2009 H1N1-related hospitalizations occurred between April and November 14, 2009. The mid-level in this range is about 213,000 H1N1-related hospitalizations.
* CDC estimates that between about 7,070 and 13,930 2009 H1N1-related deaths occurred between April and November 14, 2009. The mid-level in this range is about 9,820 2009 H1N1-related deaths.

Note: More than 95% of the increases in the estimated numbers of 2009 H1N1 cases, hospitalizations and deaths between the November 12 and December 10 estimates occurred between October 17 and November 14, 2009. (Less than 5% of increases are the result of delayed reporting in cases, hospitalizations and deaths that occurred prior to October 17, 2009.)

Swine Flu Has Infected 1 in 6 Americans: CDC
Children, young adults still bear the brunt of H1N1, with the most hospitalizations and deaths

Children, young adults still bear the brunt of H1N1, with the most hospitalizations and deaths.

THURSDAY, Dec. 10 (HealthDay News) -- The H1N1 swine flu has sickened nearly 50 million Americans, sent more than 200,000 people to the hospital and killed nearly 10,000 -- more than 8,000 of them children and young adults, a federal health official said Thursday.

"About 15 percent of the entire country has been infected with H1N1 influenza. That means about one in six people," Dr. Thomas R. Frieden, director of the U.S. Centers for Disease Control and Prevention, said during an afternoon press conference.

"That still leaves most people not having been infected and still remaining susceptible to H1N1 influenza," he added.

The swine flu continues to hit children and young adults the hardest, Frieden said. Among those who have died since the virus first surfaced in April, an estimated 1,100 were children and 7,500 were young adults, he noted. This is the reverse of seasonal flu, which tends to strike hardest at people 65 and older.

"By November 14, many times more children and younger adults have been hospitalized or killed by H1N1 influenza than occurs during a usual flu season," he said.

The swine flu has also been particularly virulent among the Native American and Alaskan Native populations, Frieden said.

"The death rate is about four times higher for this group," he said. "This is most likely largely a reflection of environmental factors and underlying conditions -- like diabetes and asthma -- that are more common, and access to health care, rather than a genetic or racial/ethnic difference."

Frieden said that, as has been noted before, the rate of H1N1 flu infections has subsided in recent weeks, but it's impossible to predict what the winter and spring might bring. About half of the experts interviewed by the CDC think there will be many more cases, while the other half is taking the opposite view. "The truth is we don't know," he said.

Meanwhile, the supply of H1N1 vaccine continues to grow, Frieden said. There are now 85 million doses of vaccine available, up another 12 million doses from last week.

"This is a good window of opportunity to get vaccinated," he said. "We don't know what the future will hold in terms of H1N1 influenza."

The swine flu continues to produce mild infections in most people, with recovery taking about a week. But certain groups remain at risk for complications, including pregnant women, children and young adults, and people with chronic health problems, such as asthma, diabetes and heart disease.

Frieden also noted that cases of the regular, seasonal flu have begun to show up. Influenza B has already killed one child, he said.

So far this year, about as many people as last year have gotten a seasonal flu shot. With 109 million doses of seasonal flu vaccine available, most of the supply has been shipped. But, people are still experiencing shortages of this vaccine, Frieden said.

In related news, health officials in Vietnam said they have identified a cluster of swine flu cases resistant to the antiviral drug Tamiflu. The cases involved seven people who had traveled together on a long train ride in July. They did not know each other before the trip, and all recovered, according to a report in the Dec. 10 issue of the New England Journal of Medicine.

An estimated 100 cases of Tamiflu-resistant H1N1 flu have been reported worldwide.
