Zombie Infection via scratches?
So, if you get attacked by a zombie;
Do you have a 7% chance of getting the scratch? or,
Do you get a scratch via some other probability (bite, or scratch, or laceration, or miss)
and then if you get the scratch it has a 7% chance of getting infected?

If its a 7% chance to get infected (which means death), can you use a disinfectant to prevent a scratch from a zombie from getting infected with the zombie virus? Does it reduce the chance to get infected? whats that chance? Like, if you have a 7% chance of the scratch becoming infected, but you use disinfectant on it, does that reduce the chance of it getting infected to say, 5% (or w/e the % is, should that be the way it works?)

In other words, why would one bother to disinfect a zombie scratch?

There are two types of infection: zombification infection and wound infection.

The former can only be given by zombies and cannot be cured.
The latter can be prevented by disinfection and proper care.

To prevent wound infection in case you got lucky and did not receive zombification infection from that scratch and want your wound to normally heal.

So your saying that if you get a zombie scratch, it can get infected, but not be the zombie infection? So, you would be trying to kill a wound infection, and ofc if it didnt go away, I'd assume you would realize its not wound infection, it is zombie infection

Also, to be more clear on my question. When you are scratched, or lacerated by a zombie attack, is the 7%/25% chance to get zombification calculated right then, whether you have a notification that its infected or not, or is there time in between the scratch/laceration and the infection to disinfect? So, you get scratched, 10 minutes from then it rols to see if you got the infection, and inbetween the time you got scratched, and the time it rolls for the 7% chance, you could reduce that chance to a smaller number, or clear it altogether.

Like when I get a scratch from a zombie, its not infected. It becomes infected some time later, sometimes. So, when its in its non-infected time period does sterilized rags, etc reduce the 7% chance to become infected.? I know that once its infected by the zombie virus, your dead.

Its that delay from being scratched, to having the scratch infected that has me wondering how this works. I would think that if the game rolled your 7% chance immediately upon being scratched, then the scratch would be infected immediately if you failed the roll and were infected by it. But see its not, i get the scratch, and 20 minutes later the scratch becomes infected (sometimes). So again, during that period, is there a way to prevent the scratch from becoming infected to begin with (zombie infected).

Zombie infection does not show up as the "infected" status on the health screen. If it says "infected" it only means normal wound infection. That said, you can have a zombie infection still, but you general won't know until you start getting symptoms like queasy.

Yes.

You are misunderstanding this. Only wound infections show up as big red "INFECTED" signs on the health screen, and only they can be treated and prevented by disinfection and care. Zombification infection does not show up on the health screen.

Some other parts of your questions are based on this misunderstanding so it answers them as well.

Yes, the zombification infection check is performed the moment you get hit. There are no delays.

Once again, there is no "that period". You either got immediately infected with zombification when the zombie touched you, or you did not.

In short, You have a 7/25/100% chance on a zombie sourced Scratch/Laceration/Bite of being infected by the Zombie virus. The game will not tell you if you've contracted the zombie virus; There is no clear indication of it anywhere. The only way you know you've got it is if you start getting ill several days(sandbox setting dependent) later with no apparent cause.

There is no way of modifying the chance of being Zombie Infected except the Thin-Skinned and Thick-Skinned traits at character creation. Disinfecting will not save you if you get the zombie infection- It's decided at the moment you receive the injury from a zombie, either you've got the virus now and are going to die, or you don't. There is no cure. This is how you die.

Wound infection by contrast can occur from ANY wound, zombie sourced or otherwise. You disinfect to prevent wound infections; Or to help recover from wound infections should you fail to change your bandages for too long. This kind of infection is telegraphed to the player with the red text 'infected' on the health menu. Wound infection occurs when the player fails to change their bandages for clean ones soon enough; Basically, improper care = wound infection.

Not sure why you didn't just search this since this has already been explained many times before. You're already on Steam so not sure why you wouldn't bother just searching it rather than making a new thread about it. Also where are you getting 7%? You sound like you already know the answers to your questions.

The simple solution to this whole issue is to change the 2 settings for zombification to be instant. I got so tired of dieing a while after I got a minor scratch in a fight when I thought everything would be fine.

I'd rather just know right off the bat. It's less frustrating that way... at least for me.

If you'd read, they were confused on the specifics. Not sure why you didn't just skip the topic if you had a problem with it.
