Uh oh!

I just took a masters level virology class and needless to say it scared the crap out of me... I finished my undergrad degree but i'm still in a certification program for teaching so i had to take a class to make full time student. It really is unbelievable how viruses work, and we know very little about them. I find it interesting that certain viruses we know of now have the ability to effect specific body systems, while leaving others unaffected for no apparent reason, the virus somehow distinguishes not to effect certain cells but to effect others. It's even more interesting that viruses actually don't even do much damage to your body, its your immune system that creates the symptoms associated with a virus(most of the time). Some where down the line there is going to be a virus that evolves to take over the body, much like they take over cells now. They will shut down body functions much like they can already shut down cell functions, leaving only the barebone systems needed for operation and survival. They already found simple ways to bypass the immune system, like influenza, if a serious neurological virus was able to evolve like influenza a and b i think we could very well see "zombies" running our streets. And they might even be able to evolve into more efficient zombies there after. We may see your typical dragging its feet zombie one day, and a couple years later the typical 28days later zombie.

In essence viruses would only have to evolve to effect a large scale(the body) instead of cells and zombies could very well be something in our future. It really is funny how something so sci-fi can be become real, take blackholes for instance, they used to be front and center in the sci-fi community, worm holes and all that fun stuff, 40 years later and guess what, there real, and not only that there are billions of them.

They may not come in an undead form, where u need to shoot the head to stop them, they will be ALIVE, but zombies non the less.
