(詳細はoutbreak of a new strain of flu (also known as influenza), popularly known as swine flu was discovered to have infected several people in Mexico and the states of California and Texas in the United States. On April 28 Costa Rica became the first Central American country to report the outbreak of the virus, with a confirmed infection. As of November 4 the Costa Rican Ministry of Health had 1,596 confirmed cases, 1,275 pending cases, 8,000 already discarded, and 38 deaths. On July 31 local authorities announced that the country was selected among the sample countries that will be part of the test of the vaccine developed by Swiss pharmaceutical Novartis. The local sample will include 784 Costa Ricans ages 3 to 64. Besides Costa Rica, this vaccine prototype will be tested also in Mexico and the United States. On August 11 was confirmed that Costa Rica's President, Óscar Arias Sánchez, was infected with the A(H1N1) virus, becoming the first head of state sick with the A(H1N1) virus President Arias returned to his normal activities after one week of isolation at his home. ==Initial outbreak== The first confirmed case of influenza A (H1N1) in Costa Rica was announced on April 28, and was that of a young woman hospitalized in San Jose.〔 On April 28, Minister of Health of Costa Rica, Maria Luisa Avila confirmed the second case, a 29-year-old man hospitalized at the Hospital San Vicente de Paul in Heredia. A National Health Emergency was announced. The Ministry of Health reported the existence of two new probable cases of swine flu in the country on the morning of May 2. These were a 53-year-old man who had not traveled to Mexico, in a hospital in San Jose, and a 24-year-old woman who is recovering at home. These new patients brought the total number of Costa Ricans affected by the virus to four. Three are listed as probable cases, while one was duly confirmed by the Centers for Disease Control and Prevention in the United States. Four more cases were confirmed on May 4 by the Costa Rican "''Centro Nacional de Referencia en Virología''." All of these patients have recently traveled to Mexico.〔 Since April 29 the Ministry of Health recommended to avoid travel to Mexico, Canada, and the U.S. as the number of confirmed cases by local authorities reached eight. On May 12 the Minister of Health announced that an alert was received from U.S. authorities informing that three members from a Boston chorus, Canta Mundi, that traveled to several tourism places in Costa Rica during April, showed symptoms of AH1N1 flu after returning to the U.S. On May 13 Costa Rican health authorities announced four new probable cases, three of which had contact with the Boston chorus, and a follow-up is being done with those who had contact with the chorus. A couple of English language newspapers questioned whether the chorus members had infected locals, or rather the Boston youngsters picked up the disease in Costa Rica, as the chorus flew directly from the United States to Costa Rica. Beginning May 20 probable cases are now confirmed locally by the aboratorio de Virología del Instituto Costarricense de Investigación y Enseñanza en Nutrición y Salud (Inciensa), which now is in capacity to confirm the presence of the A (H1N1) virus in 24 hours. Previously, all samples had to be sent to the U.S Centers for Disease Control and Prevention for confirmation.〔 Among the 26 confirmed cases until May 21, six patients had contact with the Boston chorus and the Ministry of Health reported that all patients have a stable condition. 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 Costa Rica」の詳細全文を読む スポンサード リンク
