  1. A dry scab and mild itching
  2. A small bruise around the cut
  3. Spreading redness, warmth, swelling and pus ✔

Why: These signs, plus fever or red streaks, mean infection. Bites and deep punctures are the riskiest, and they need medical care.

Huh, didn't know that: Infection risk grows with dirt, delay in cleaning, and the type of wound.
