Most people think of zombies as groaning creatures with missing limbs, covered in blood and with ripped clothing, but that's only what they look like in movies and comics, meaning that there might be some more subtle details that you should be able to spot to identify an infected person. These things include:

~ Irrational thinking

~ Uncontrollable anger and hunger

~ Slow walking

~ Clearly lower intelligence

~ No social skills

~ Groaning and hissing

~ Looking sick- pale with a cough and or high temperature
