The cause of a zombie apocalypse

My opponent mentioned that round 2 of this debate will be for refutal, so I won't criticize just yet. To my understanding, this is a fun debate so there is no need to be picky on spelling/grammar, as it is for the information. I also assume that this is a cause and effect debate, so please vote spelling/grammar on that. I thank the opponent for posting his argument, and I shall start with mine. Background Over the course of history, humans have had a harder time coping with an lethal pandemic than the lack of electricity. Over many years, doctors and scientists have found vaccines and cures to the most deadly and wide spreading viruses of the past. What scientists also know, is that a virus will do anything it needs to do, to survive. In this case viruses need to genetically mutate. This has been shown almost every virus known. When a new virus emerges, scientists and doctors need to find a cure. The problem is, the viruses mutate at a much faster rate than the people can find cures for. My opponent may try to use the argument that the Center of Disease Control would help stop it but in many shows, including AMC's The Walking Dead, the CDC have been found to be inefficient. Other ways to think about this is the iPhone/iPad game called "Plague." The Virus The a zombie apocalypse would begin with the creation of a new virus. Since viruses have been known to rapidly change to survive, this particular virus will have the ability to transfer through oxygen. The importance of this virus, and how it is more deadly than the loss of electricity, is that it would happen so sudden. If the virus began infecting one person, wherever that person breathes, everyone near him would also be infected. Nowadays, people interact with others so much, so even if the virus would originate in one continent, it would travel through the people on planes also. Similar to the idea of The Walking Dead, the symtoms would only show if the person were to be either bit, or if they died by another cause. If they were bit, the amount of cells infected would transfer through the other person's body. At that time, the victim would only have two options: remove the infected part or die. The victim would have only a few minutes to make the decision because by that time, the virus would spread throughout the body, and the person would become a zombie. By dying of another cause, such as human or natural deaths, the person will discontinue to produce enough T-cells to fight off the virus. The cells will then have enough energy to restart parts of the brain that would sense hunger and infection. After a while, there will be few, if any people to fight off the disease.People will go in hiding, not knowing that at this time things are not bound to get better. By surviving, they are only buying themselves more time until they get infected also. The people of any resistance would be in danger because if any of the survivors die, they could infect the entire group. Another reason why a virus would be the most deadly start of an apocalypse, is that time is of the essence. Man can only fight off the disease for so long. But how viruses work, is they reset the DNA of each cell to fit their own needs. When the cells keep regenerating, they become virus factories. After a while the person will have more infected than non infected cells. People will become paralyzed before the meet the virus makes it way to the brain, which would be a slow and painful death. The fastest way for the population of zombies to increase, would be if an air-traveling virus were to be present. People will not be able to fight off the virus, and no matter how the person acts, they will eventually become a zombie, and once that happens, there will be no one left to talk about it.
