ニューヨークで12人が死亡、55万人が感染か/米国医療事情 新型インフルエンザ

 ニューヨーク市当局は水曜日、豚インフルエンザによる3人の死者を報告し、推計で50万人以上の感染者がでたと言う。
画像 4月以降の死者は12人となった。3人の新たな死者は、30代、50代、65才以上であった。入院者数は530人となり、新たに102人が入院した。週末は1日35-40人が入院した。電話調査では、5月1-20日の間で、熱・咳・咽頭痛などのインフルエンザ様の症状を示した人は 6.9%にもなった。この数値からすると、約55万人が感染した可能性がある。そのうちの0.1%にあたる500人が入院したので少数であり、ウイルスが穏やかであることを示している。1,005家庭の調査では、罹患率は震源地のクイーンズで最も高い9.4%で、最も低いマンハッタンとブロンクスでは4%以下だった。Dr. Weiss によれば、普通のインフルエンザ季節には、人口の5-20%は病気になり、人口の10%の控えめな見積りを使えば、800,000人となるだろうと言う。
 市当局の発表は次第に不明瞭となってきており、今回の発表では基礎疾患にさえ言及していない。保健局広報のJessica Scaperottiによれば、感染が広範囲に及んでおり、市としてはもっと大局的な視点で見ていると言う

12 Flu Victims Have Died, and Ill May Total 550,000

New York City officials on Wednesday reported the deaths of three more people with swine flu, and estimated that more than half a million New Yorkers may have become sick from the virus.

The latest deaths bring the city’s total to 12 since the outbreak began in late April. The city health department said that one of the latest victims was 30 to 39 years old, one was 50 to 59 years old and one was over 65.

The city also announced 102 new hospitalizations since its last report on Monday, bringing the total hospitalizations to 530.

Dr. Don Weiss, director of surveillance for the Bureau of Communicable Disease, said that what looked like a spike in hospitalizations actually represented catching up from a lag in reporting over the weekend. He said that hospitalizations were running at the rate of 35 to 40 a day, and “don’t appear to be going up or down appreciably.”

Health officials said that in a telephone poll of New Yorkers, 6.9 percent of those surveyed reported having flulike illness, like fever and cough or a sore throat, between May 1 and May 20.

Extrapolated to the general population, that would mean that about 550,000 people could have become sick with the virus. The 500 who have been hospitalized make up a tiny proportion ― about one-tenth of 1 percent ― of those who became ill, an indication of how mild the virus generally has been, officials said.

“The findings don’t tell us exactly how many New Yorkers have had H1N1 influenza,” Dr. Thomas A. Farley, the city’s new health commissioner, said in a statement. “But they suggest it has been widespread and mild in most people.”

The survey of 1,005 households found that the prevalence of flulike illness was highest in Queens, where the outbreak began, with 9.4 percent, and lowest in Manhattan and the Bronx with just below 4 percent.

Officials cautioned that some of those who reported flulike symptoms may have had seasonal flu, strep throat or similar illnesses.

In an ordinary flu season, Dr. Weiss said, 5 to 20 percent of the population becomes ill, and using a conservative estimate of 10 percent of the population, that would be 800,000 people.

The city’s descriptions of those with swine flu who have died have become progressively vaguer, dropping information like exact age, sex and home borough. By Wednesday, the city had stopped saying if victims had an underlying health problem that put them at more risk from the virus.

Jessica Scaperotti, a health department spokeswoman, said the city had become less specific to guard patient confidentiality, but also because the disease had become so widespread that officials were more interested in the big picture. “We’re not really focused on individual cases,” she said.
