Quick answer

Wound Infection is created when a bleeding wound is treated with a non-disinfected dressing/tool or is allowed to close on its own.

Quick answer

The cause of the original bleed does not matter: Wound Infection is created by a non-disinfected dressing or tool, or by letting a bleed close on its own.
Listed infection chances: unclean Bandage 5%, unclean Rags 15%, unclean Bandana 15%, unclean Sewing Kit 30%, letting the bleed heal on its own 40%.
Stage 1 lasts about 20 minutes: periodic pain sounds, light visual blur and stamina recovery about 50% slower. Treat it by disinfecting the wound directly.
Stage 2 is systemic: louder pain, more frequent blur, Fever, shaking hands, severe stamina-regeneration loss, extra Water drain and continuous Health loss at 2.5 per minute. It requires Tetracycline.
Disinfected status can be lost when a dressing is damaged: inspect the current tooltip before it touches an open wound.

Guide details

Prevention window: fresh bleed, no infection symptoms — use a disinfected dressing; direct disinfectant can prevent infection if appropriate
Stage 1: pain noises plus mild blur plus fatigue and slow stamina — apply Disinfectant Spray, Iodine Tincture or Alcoholic Tincture directly to the wound
Stage 2: Fever plus stronger blur and pain plus shaking plus Health and Water loss — Tetracycline required; stabilize Water and Health while sequential doses work
Tetracycline is not the Stage 1 treatment, and topical disinfectant alone is no longer the cure once Stage 2 is systemic

Wound Infection starts with wound treatment, not with the thing that cut you

Current vanilla infection probabilities illustrate the risk difference: an unclean Bandage is lower risk than an unclean Sewing Kit, while letting a bleed self-heal has the highest listed chance. The exact number matters less than the operational rule—dirty treatment is a gamble, and “I will just wait until the bleed stops” is not a safe plan.

Stage 1: pain, blur and slow stamina recovery

Stage 1 lasts about 20 minutes in current vanilla. Expect periodic pain sounds, light visual blur and stamina recovery around 50% slower. This is the window where local wound disinfection is the clear treatment path: Disinfectant Spray, Iodine Tincture or Alcoholic Tincture can be applied directly to the wound.

For Stage 1 Wound Infection, disinfect the wound directly with Disinfectant Spray, Iodine Tincture or Alcoholic Tincture. Tetracycline is not the Stage 1 treatment.

Stage 2: the infection becomes systemic

Once Stage 2 begins, the symptoms become much harder to ignore: louder pain, more frequent blur, Fever, shaking hands, severe stamina-regeneration loss, extra Water drain and continuous Health loss. Current vanilla data lists Health loss at 2.5 per minute; a full-health survivor can die in roughly 40 minutes if the Stage 2 infection is not cured.

Stage 2 requires Tetracycline. Topical disinfectant can still affect the wound locally but is no longer the cure for the systemic stage. Take one effective Tetracycline dose, let the medication effect run, and continue the sequential treatment if the disease remains after the effect expires.

Prevention odds: why disinfecting is worth the time

Disinfected status can be lost when a dressing is damaged. Do not assume an item remains safe forever because you disinfected it yesterday; inspect the current tooltip before it touches an open wound.

Stage decision tree

Wound-closing method | Listed infection chance

Unclean Bandage | 5%

Unclean Rags | 15%

Unclean Bandana | 15%

Unclean Sewing Kit | 30%

Let bleed heal on its own | 40%

What you observe | Treat as | Action

Fresh bleed, no infection symptoms | Prevention window | Use disinfected dressing; direct disinfectant can prevent infection if appropriate.

Pain noises + mild blur + fatigue/slow stamina, infection started recently | Stage 1 | Apply Disinfectant Spray / Iodine / Alcoholic Tincture directly to wound.

Fever + stronger blur/pain + shaking + Health/Water loss | Stage 2 | Tetracycline required; stabilize Water/Health while sequential doses work.

FAQ

Does it matter what caused the cut?

No. The cause of the original bleed does not matter. Wound Infection is created when a bleeding wound is treated with a non-disinfected dressing or tool, or is allowed to close on its own. Prevention is simple: stop the bleed and use equipment that actually shows the Disinfected state.

What treats Stage 1?

Disinfect the wound directly with Disinfectant Spray, Iodine Tincture or Alcoholic Tincture. Tetracycline is not the Stage 1 treatment. Stage 1 lasts about 20 minutes in current vanilla.

Is disinfectant enough for Stage 2?

No. Once Stage 2 begins, topical disinfectant can still affect the wound locally but is no longer the cure for the systemic stage. Stage 2 requires Tetracycline: take one effective dose, let the medication effect run, and continue sequential treatment if the disease remains after the effect expires.

Is a bandage I disinfected yesterday still safe?

Not necessarily. Disinfected status can be lost when a dressing is damaged. Do not assume an item remains safe forever because you disinfected it yesterday; inspect the current tooltip before it touches an open wound.
