Infectious Mod

I think workshop has enough zombie infection addons so I'll keep it short, you get scratched you'll get infected, you get infected and you turn into a zombie after death.
Zombie transformation is irreversible, if you turn into a zombie in singleplayer, you'll have to find a way to ♥♥♥.
Might have quite a few bugs, but since I'm not as responsible and passionate as I used to be, You might have to wait for a while.

Virus Detector scans humans passing by for the virus, and those in incubation can be detected as well;
Virus Suppressant temporarily counteracts the infection and maximizes the incubation period, but does not completely cure the infection;
Virus Vaccine fully cures infections, but there are side effects for a period of time where movement slows down, and immunity to infections for a period of time after vaccination. Can hide needles in props;
Radio can be seen as a control point; the infected will try to get close to the radio and destroy it, and manning it will protect the radio from damage. The radio will block single and global spawners from spawning zombies in the area;

Virus Sample is a bottle of highly toxic infected blood, and being hit by it will surely result in an infection with an incubation period;
Virus Vial can cause infections without an incubation period. Can hide needles in props;

Infected There are NPC infected and Nextbot infected. NPCs are based on the vanilla zombie NPCs so they can move smoothly but can't break down doors and have a fixed speed;
Nextbots have similar actions as infected players, with armor and fixed speed, but can easily get stuck anywhere in the map;

Point Spawner can be used to place Infected in specific locations, and can be paired with a radio;
Global Spawner will spawn infected around human players, not very reliable in maps where areas are not connected so it's recommended to use point spawner instead;
Global Spawner will stop spawning when there are no alive human players, or on maps without ai node or navmesh.
The Experiment displays the ratio of infected to humans on the map, and starting the experiment will transform a certain percentage of humans across the map.
