Here's the stats from the Combat Arms wiki page. (Let me know if I can link it here.)
The Infected:
* are immune to poison/toxicity
* are immune to water/drowning damage
* are immune to height damage/falling.
* are immune to flashes/bright lights.
* have high speeds (Faster then Viper or the Light Vest & Military Bandanna combination)
* have 2.5x the stamina of a normal human.
* are rather resistant to bullet damage. (The current maximum is 6-15.)
* are moderately vulnerable to melee damage (Though melee damage is extremely discouraged, as the human will easily become infected)
* are moderately vulnerable to explosives and fire damage (These weapons are the best choice if a human wishes to kill a zombie)
* have extra hp depending on the vest and the type of infected:
o Light Vest-
450 hp for a Host infection and 225 hp for a normal infection.
o Medium Vest-
600 hp for a Host infection and 300 hp for a normal infection.
o Heavy Vest-
800 hp for a Host infection and 425 hp for a normal infection.
I hope I helped.
