Infections are the result of germs and other microorganisms entering the body. They may enter the body in a variety of ways including open wounds or natural openings such as the eyes.

Zombie infections behave primarily the same way. The infection is typically spread through a zombie bite that pierces the skin.

Symptoms include:

• Caught in a state between life and death
• Insatiable hunger for living flesh
• Mindless wandering
