The horrific face-eating arrest in Miami and several other seemingly subhuman acts has many people wondering what's behind this flesh-munching wave of terror.

A zombie apocalypse, however, is not what we should be worried about, at least according to the federal government.

Over the years the Centers for Disease Control and Prevention has released a couple of tongue-in-cheek "zombie warnings," which really are just disaster-preparedness stunts. But on Thursday, the agency made it official: Zombies don't exist.

"CDC does not know of a virus or condition that would reanimate the dead (or one that would present zombie-like symptoms)," wrote agency spokesman David Daigle in an email to The Huffington Post.

Nevertheless, recent incidents in which humans reportedly ate human flesh have the Internet in a firestorm, with "zombie apocalypse" being Google's third most popular search term by Friday morning.

The zombie craze seemed to start with an attack in Miami, when Rudy Eugene, 31, was killed by cops while in the process of eating almost the entirety of a homeless man's face off. The victim, Ronald Poppo, miraculously survived, but doctors are having a hard time figuring out how to put his face back together.
僵尸狂热似乎是始于此前在迈阿密发生的一起袭击事件,即年仅31岁的鲁迪尤金在几乎啃食完一个流浪汉的整张脸的过程中被警察击毙。受害者Ronald Poppo奇迹般的活下来了,但是医生们正努力的想如何才能将受害者的脸恢复。

Then, 21-year-old Alexander Kinyua of Maryland allegedly admitted to dismembering his roommate and then eating his heart and brain.

Gawker fingered a "mysterious rash" breakout at a high school in Hollywood and other parts of Florida -- which hazmat and disease control teams still can't explain -- as further proof that zombies are taking over.

Zombie-like characteristics have been confirmed in the animal kingdom, just not in humans. A newfound fungus in a Brazilian rain forest -- called Ophiocordyceps camponoti-balzani -- is known to infect an ant, take over its brain so as to move the body to a good location for growth, and then kill the insect.
类僵尸现象在动物界里已经被证实,但在人类世界里却没有相关证明。在巴西雨林里最新发现的一种叫Ophiocordyceps camponoti-balzani的真菌,就被证实能够感染蚂蚁,并控制蚂蚁的大脑,迷惑蚂蚁到一个更利于真菌生长的地方活动,然后将其杀死。

Yet Daigle dismissed "fictional viruses" like Ataxic Neurodegenrative Satiety Deficiency Syndrome, noting that other triggers have been alleged to cause zombie-like symptoms.

"Films have included radiation as well as mutations of existing conditions such as prions, mad-cow disease, measles, and rabies," he said.

But recently, some have found truth stranger than fiction. "Action must be taken now before an outbreak!" an anonymous reader told The Huffington Post. "Zombies may be subdued by destroying the brain or removing the head. It is now your responsibility to prevent the apocalypse."
