After they free the monkeys, the animals turn on them and bite them hence inflicting them with the virus. The virus soon becomes an epidemic afflicting anyone who comes in contact with the blood through any contact with the infected people. John Wyndham continues to spin the same post-apocalyptic tale although his zombies or vampires take on a rather an unprecedented form. The author presents the zombie character as plants called Triffids that have the ability to walk by upping their roots. However, the catastrophic attribute of these creatures is the lethal venom that they have in their sting, and it is often fatal to humans. The three depictions significantly differ from the traditional definition that almost teetered significantly toward a religious perspective. The directors and author imply that human beings were the cause of the entire affliction that they were facing. In The Omega Man, Robert Neville explains that the virus epidemic came about due to the germ warfare between Russia and China where both sides employed biological weapons. In 28 Days Later, Jim is the main protagonist that makes a claim about the people responsible through his explanation of the events. He states that the activists had gone to set the monkeys free while the scientist was experimenting with a lethal virus capable of wiping off all trace of humanity from the face of the earth. It, therefore, suffices to say that human rights were over-zealous in their quest, and the scientists were equally guilty for summoning up the mother of plagues.
