Do Humans Get Swine Flu(人會得豬流感嗎)

【中文原文】

人會得豬流感嗎?

　　　　　　通常豬流感不會感染人類.美國曆史上,每一兩年在接觸活豬的人羣裏會有一例感染.但從2005年12月到2009年1月間,人類感染豬流感病例上升了.這段期間出現12例病例.其中11例的病患有直接或間接活豬接觸史;剩下這一例未知.這種病例上升可能和疾病報控系統完善有關,但疾病控制和預防中心CDC指出"豬流感病毒的基因變化和其他因素可能也有關係."這種新病毒與以往不同 ,它正在感染人類,世衛組織官員正密切關注其發展.

　　　　　Do Humans Get Swine Flu?

　　　　　　Normally, swine flu bugs don't infect people. Historically, there's a case every year or two in the U.S. among people who have contact with live pigs.

　　　But from December 2005 to January 2009 there was an uptick in swine flu cases. There were 12 human swine flu infections during this time. Eleven of these people had direct or indirect contact with pigs; in the twelfth case it was not known whether there was pig contact.

　　　It's possible this uptick was due to improved reporting systems, but the CDC says "genetic changes in swine flu viruses and other factors might also be a factor."

　　　The new swine flu virus is different. It's not yet clear that it's here to stay. But it is infecting humans, and that has world health officials keeping a close eye on it.
