The One Rule That Matters Cross-Verified
A zombie bite is 100% infection, and the infection is incurable — two independent 2026 field guides state it in the same terms. The progression after a bite: distress and a queasy moodle within a few hours, then fever, ending in death. There is no cure, no grace mechanic, no trick. Characters with a bite should spend their remaining hours on storage runs and base projects, not on medical loot.
Bites are also not the same threat as scratches and lacerations. Those carry a smaller but real chance — neither guide publishes the exact percentage (treat any number you see elsewhere as unverified) — and their mechanism is bacterial wound infection, which is fully reversible with cleaning and medication.
The Treatment Ladder Cross-Verified
| Step | Item | What it does |
|---|---|---|
| 1. Clean | Disinfectant | Sanitizes damaged tissue before covering — order matters |
| 2. Cover | Bandage → sterilized bandage | Stops bleeding; the sterilized version suppresses infection far better |
| 3. Close | Sutures / needle & thread | Closes large lacerations |
| — | Tweezers | Removes embedded debris (glass, shrapnel) — debris blocks natural healing |
| — | Splint | Immobilizes fractures |
| — | Painkillers | Manages pain and fever |
| Later | Antibiotics + vitamins | Resolve bacterial infection once it appears |
Neglected dressings rot into fresh infection — a bandage is not the end of treatment; check and re-dress.
Why First Aid Pays For Itself Deep-Tested
Higher First Aid improves dressing quality, lowers complication chance, speeds healing, and at sufficient skill auto-applies supplies in a fight. Leveling route: repeated bandaging (sterilized preferred) and treating co-op patients; the Nurse occupation opens at First Aid +3 — the point math is in the trait tier list and the XP table.
Sources & Verification
| Source | Type | Sections Used |
|---|---|---|
| games.gg — Project Zomboid First Aid Guide | Third-party field guide (rev. 2026-08-11, 42.20) | Bite fatality, treatment ladder, First Aid leveling |
| build42guide.wiki — Build 42 First Aid | Community guide (checked 2026-09-27 vs 42.20.2) | Scratch/laceration risk, wound care order, antibiotics |
Both sources state the bite rule in the same terms; published percentages for scratch infection do not appear in either, so this page prints none.
