Can you survive a zombie bite in Project Zomboid?

No. On Project Zomboid's default sandbox settings, a zombie bite carries a 100% chance of transmitting the Knox Infection, and once it takes hold there is no cure — no antibiotic, no trait, no amount of rest reverses it. A scratch (about 7%) and a laceration (about 25%) are a different story: both are genuinely survivable if you disinfect and bandage the wound the moment it happens.

The confusion comes from the game having two separate infections that share the same word. A wound infection — the kind a plain cut or an unwashed scratch can develop — is a mundane bacterial problem that antibiotics and first aid actually cure. The Knox Infection, the zombie virus itself, is a different system entirely, and treating it like a wound you can bandage away is the mistake that gets people killed on their second week. Only a bite guarantees the Knox Infection; scratches and lacerations only carry a chance of it, on top of the ordinary wound-infection risk you'd get from any untreated cut.

You can tell which one you've got by opening your health panel: a wound there is labeled bitten, scratched, or lacerated, and that label is the ground truth — not the moodles, which lag behind it. If the label says bitten, the honest plan is to use the time you have left, not look for a way out. If it says scratched or lacerated, disinfect it immediately, bandage it — a sterilized bandage lowers the risk further than a plain one — and don't skip that step because the wound looks minor.

The moodles are the early warning that follows once the Knox Infection actually starts: Queasy shows up first, and while it also comes from food poisoning or lingering near a corpse, Queasy with no such explanation and a recent bite or scratch in your history stops being a coincidence. Anxious and a heart icon that won't stop shaking follow as the infection progresses, ahead of nausea and fever. From there it's a matter of days before death and reanimation — there's no fixed countdown worth memorizing, only the certainty that it doesn't stop.

The one thing that changes this rule is the sandbox setup itself. Zombie infection transmission is a sandbox option, and some custom setups turn bite mortality down or off entirely, trading permadeath for a game about scarcity instead of one unlucky bite ending a character. If you're unsure which you're playing, check your world's sandbox settings before assuming the 100% figure applies.
