Analysis Post World War Z
In my book World War Z the text says" I found "Patient Zero" behind the locked door of an abandoned house across town" Some other quotes that support and describe who patient zero is " But the boy jerked again and I heard his left arm snap." This describes patient zero because it shows that he is infected with whatever the disease is. He is also very weak. Some inferences that I have drawn from the text are that he is the very first zombie and he will infect the rest of the world with just one bite.
