The Infected are the main antagonists in the horror film 28 Days Later, the secondary main antagonists in its sequel 28 Weeks Later and the primary antagonists on its comic adaptation, 28 Days Later: the Aftermath (as well as possible main or secondary antagonists in the possible third film 28 Months Later). The Infected, as their name suggests, are living people infected with the highly contagious Rage Virus, which has warped their brain cells to make them see all living people as objects to be hunted down and slain ruthlessly.
