The World Health Organization (WHO) and the Argentine health authorities expressed their concern from the beginning of the outbreak, that the imminent arrival of the southern winter could cause "more serious" effects in the southern hemisphere than those caused in Mexico, and could lead to a rebound of the epidemic around the world. The flu or ''influenza'' is mainly a seasonal disease that becomes most prevalent in winter.〔("Weather and the Flu Season" ), ''NPR Day to Day'', December 17, 2003.〕 The first infection was confirmed on May 7 in a man who had come from Mexico City and had entered the country without symptoms on April 24. The second case was detected on May 22. Towards the end of May infection started in some schools in the northern community of the City of Buenos Aires and its suburbs, the main part of the country affected by the epidemic. On June 15 the first death was announced: a three-month-old baby in the Greater Buenos Aires area. In the second half of June, coinciding with the onset of winter, the virus was widely transmitted in Buenos Aires and spread to other parts of the country, especially the Province of Santa Fe, with its center in the city of Rosario. On June 29, the Government decided to close schools throughout the month of July, a measure which affected 11 million students. Pregnant women and other categories at risk were also dispensed from working. The measures taken by the authorities were primarily targeted to limit contagion during the winter months until the start of spring. The peak of infection lasted from the end of June until the beginning of July, increasing normal hospital demand fivefold and causing the collapse of the systems organizing hospital wards, home doctors and work place doctors. The most affected area was Greater Buenos Aires, home to some 12 million people. It was estimated that up to 10% of the population of that region (approximately 1,200,000 people) could be affected by the pandemic of influenza A. In Argentina, seasonal flu outbreaks kill about 4,000 people each year, equivalent to a rate of 10 deaths per 100,000 inhabitants. The contingency plan developed in 2006 to face a possible influenza pandemic estimated that the dead could reach 13,000 in the event of a moderate rate of infection (15%) and 30,000 in the event of a serious infection rate (35%). ==Timeline== 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 Argentina」の詳細全文を読む スポンサード リンク
