Maybe a type of 'rage virus' but it would be EXTREMELY risky to unleash as controlling it could fail due to mutations, quarantine problems, rate of spread, etc - if it mutates then any antibodies would suddenly become completely useless.

Quarantines NEVER work the way they should - especially in a panic people ALWAYS find ways of getting past quarantines and spreading any virus.

It's a lot easier just to poison and kill people rather than risk an out of control pandemic - especially if the 'virus' infects any of the millions of different species of animals and spreads cross-continent and out of control.

Just look at hospitals - even the cleanest hospitals with strict protocols seem to create more deadly illnesses that need more research and money to find cures or stop the spread.


As for typical zombies, that seems like Hollywood and fictional creativity more than anything factual - a reanimated body, if possible, would still fall prey to the weather, hungry animals, brain degradation, muscle degradation, etc, etc - the body is an organism like any other and will starve and dehydrate like any other. If a zombie was possible it would be dead in a short matter of time.

Although, any act of God is exclusive and may well be a reality:)
