In April 2009, a mysterious substance sent the world into a panic. A substance that can bring about death, the loss of a real person, a living human being. A disease raging through the crowds is a virus undetectable by all the existing most powerful tools -- the virus the World Health Organization calls Swine Flu. Recently, the flu is almost universal. 
And despite advances in science, there are still plenty of unknowns. We still don't know much about how a virus survives, other than the fact that it has to infect something else like human to replicate. Why is there a virus? We don't know the answer to that question.


2009年4月,一種神秘莫測(cè)的物質(zhì)讓世界陷入了恐慌。那是一種能帶來(lái)死亡的物質(zhì),隨之失去的是一個(gè)個(gè)實(shí)實(shí)在在的人,鮮活的生命。疾病正在人群中肆虐,病源是現(xiàn)有最強(qiáng)大的工具都無(wú)法探測(cè)的生命體——病毒,世界衛(wèi)生組織稱之為豬流感。如今它已幾乎遍布全世界。
盡管科學(xué)在進(jìn)步 ,未知依然大量存在。我們基本不清楚病毒該如何生存,只知道病毒必須感染其他生物才能進(jìn)行復(fù)制。為什么會(huì)存在病毒?我們并不明確問題的答案。
