豬流感是什麼?

　　　和人一樣,豬也會得流感.有4種不同的A型豬流感病株常在豬之間傳播 .最近幾種豬流感病毒屬於H1N1和H3N2亞型.豬罹患流感後一般不會致死.最新爆發的這種感染人類的豬流感病毒很不同尋常.它有可能已從豬,鳥和人流感病毒中獲取了基因片斷.並且已從本來不會在北美出現的歐亞豬流感毒株類型裏獲取了基因.

What Is Swine Flu?

　　　Like humans, pigs get the flu. Four different type A swine flu strains commonly circulate among pigs. Most recent swine flu viruses have belonged to the H1N1 and H3N2 subtypes. Pigs typically get sick but usually don't die from swine flu.

　　　The new swine flu virus infecting humans is very unusual. It's somehow acquired genes from swine, bird, and human flu bugs. And it's also got genes from Eurasian swine flu viruses that aren't supposed to be in North America.
