(詳細はpandemic of a novel strain of the influenza A/H1N1 virus, commonly referred to as "swine flu", in the spring of 2009. The earliest reported cases in the US began appearing in late March 2009 in California, then spreading to infect people in Texas, New York, and other states by mid-April. Early cases were associated with recent travel to Mexico; many were students who had traveled to Mexico for Spring Break. This spread continued across the country's population and by the end of May there were approximately 0 confirmed cases throughout all 50 states. On April 28, 2009, the director of the Centers for Disease Control and Prevention (CDC) confirmed the first official US death of swine flu, a 23-month-old toddler from Mexico who died on April 27 while visiting Texas.〔 〕 By June 24, 132 deaths had been attributed to the virus. As of January 11, 2010, at least 13,837 deaths were attributed to the virus worldwide, and at least 2290 deaths in the US were confirmed to be due to the virus. The CDC suspects, however, that the total number of deaths in the US is much higher than the official total, as some deaths probably went unconfirmed. ==Alabama== On May 2, 2009, the Alabama Department of Public Health confirmed the first case of H1N1 (swine flu) in Madison, Alabama, one of two probable cases previously identified at an elementary school in Madison. As a result, all public schools and most private schools and daycare centers in Madison County, Alabama, including the cities of Huntsville and Madison, closed for two days. After meeting with the state public health officer on May 3, 2009, all Madison city elementary schools were to be closed through May 13, 2009,〔 〕 but were reopened after the CDC updated its guidance to schools. As of December 5, 2009, the Alabama Department of Public Health reports 2453 confirmed and 36 deaths from swine flu. As of January 9, 2010, Alabama was the only US state reporting widespread A/H1N1 flu activity. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2009 flu pandemic in the United States by state」の詳細全文を読む スポンサード リンク
