Since the new flu strain--named A(H1N1) or Swine Origin Influenza Virus (SOIV) to differentiate it from the seasonal H1N1--first emerged in Mexico and the United States in April, it has spread to 74 countries around the globe. The objectives of this article are to describe the initial stages of the epidemic in Louisiana and to draw some epidemiologic lessons for the future, which could be particularly useful if the pandemic continues during the winter season 2009-2010. Between April 22, 2009 (date when the first specimen was collected) to May 31, 2009, a six week period, there were 133 cases of SOIV infection detected in Louisiana. Cases were diagnosed in late April in several regions of the state, showing that when the first cases had been identified in Mexico and California, the infection was already widespread in Louisiana. The most affected age group was between the ages of five and 25.
自这种新型流感毒株——命名为A(H1N1)或猪源流感病毒（SOIV），以区别于季节性H1N1——4月首次在墨西哥和美国出现以来，它已蔓延至全球74个国家。本文的目的是描述路易斯安那州疫情的初始阶段，并总结一些未来的流行病学经验教训，若2009 - 2010年冬季大流行持续，这些经验教训可能会特别有用。在2009年4月22日（采集首个样本的日期）至2009年5月31日这六周期间，路易斯安那州共检测到133例SOIV感染病例。该州几个地区在4月下旬诊断出病例，这表明当墨西哥和加利福尼亚首次发现病例时，该感染在路易斯安那州已经广泛传播。受影响最严重的年龄组在5岁至25岁之间。
