Rick Grimes. Chandler Riggs. Andrew Lincoln. Yes, they turned because they are already infected. Everyone is infected, regardless of being bitten or having an open wound. The belief is that the virus went airborne, meaning it's transmitted via respiratory infection vectors. They breathed in the virus through lung tissue.

Why they turned so quick seems to be due to individual biology, maybe immune system responses. In the CDC, the scoobies see a MRI of a person, alive, but dying due to meningitis like infection of the brain by the Zombie virus this contradicts the whole zombie virus doesn't kill you thing, but meh.

The patient dies. Then the Zombie virus kickstarts the brainstem. The corpse is shot through the brain. Notice the time code! Other walkers are seen to turn just as quick.

Shane reanimates in what seems like a minute. That's more Plot convenience than a realistic attempt at science, but given 4 minutes is shown to be a canon, scientifically proven timing, its believable as a standard deviation.

Before Dr. Jenner commuted suicide at the CDC, he told Rick that everyone is infected. I think that sometime during the apocolypse, the virus became airborne, maybe due to the growth of dead walkers piling up, or something else. The virus became part of the air, and as the survivors inhaled, the virus, along with oxygen and carbon dioxide, traveled through their bloodstream, spreading throughout their bodies.

But, in order for the virus to take over the bodies of the survivors, they have to either die naturally, die in the hands of someone else, or get bitten or scratched by a walker.

In the TV show The Talking Dead , they explain it as the zombie virus also known as the walker virus being airborne. This simply means that if a person ever gets an open wound such as a cut on the face or hand or anywhere else on the body, you already have the zombie virus in you. So when Carl was shot, that means that zombie virus got in him through the gunshot wound but he wasn't turned over to a walker because he never died from the wound.

On the other hand, both Rick and Shane had wounds on their hands from the previous episode when they cut open their hands to attract the zombie to the gate and to the opening in that bus door which means that the walker virus was put into both of them. Shane was changed over because if you noticed he had no wounds directly to the brain, only the heart which would allow him to "rise up" as a zombie. In the episode where the group that is lead by Rick goes to CDC, in the video it shows that the zombie virus only effects the brain stem making it reanimate leaving the rest of the body cold and dead.

So if the virus only effects the brain then that means the only way you can actually be killed is if you are shot, stabbed, slashed, or have anything slam through the skull puncturing the brain. So the only way you can actually be killed and remain as a dead corpse is if you are shot through the head or if you have any sort trauma to the brain that causes it to be punctured. Everyone already has the virus. If they are bitten by a zombie then it kills them and makes them a zombie.

If they die naturally and do not receive a bullet or blow to the head, they will "rise" as a zombie. If bitten, they will turn to a zombie unless the sustain a head blow; then they will become a corpse. Shane, just like everyone else, has the virus in him.

When he gets stabbed by Rick, he rises as a zombie because no trauma was dealt to his head. Once shot in the head he is a corpse.

Randall also had the disease and he was killed by breakage his neck and when was left there "dead" rose as a zombie soon after. Then again, it could take a very long time say, six hours at most to "re-animate". If you overdose on drugs and die, you become a walker. If you stub your toe and get an infection AND die, you become a walker. If you get your neck snapped and, well, yunno, die, you come back as a walker. If you are shot, stabbed, or badly bludgeoned in the head, however, you stay dead and do not come back as a walker.

If you die and have not become a walker yet, you can get shot, stabbed, or bludgeoned in the head to prevent re-animation. Hope this helps. Explore Wikis Community Central.
