The Forest Wiki

Infection, also known as blood infection, is a player status effect was added in the v0.29 update.


The player has a 25% chance to acquire it when being physically attacked while bloodied or when hitting a dead body, which comes from skinning animals and fighting cannibals in hand-to-hand combat.

In order to cure the infection, the player must use Aloe Vera. The infection will not go away on its own.

Having the infection status effect lowers the player's base strength.

The impacts on strength are temporary, but requires longer times to chop trees, and reduces the overall effectiveness of weapons and tools. Having an infection also halts the progression of the strength stat, potentially elongating the already slow advancement of the stat.

Effects and Formula[]

  • Effects
    • Lowers Strength by 10%
  • Formula:
    • 25% Chance when hitting a dead body
    • 25% Chance when hit physically while bloody

Known Bugs[]

  • Occasionally the infection will cure on its own. It is unclear whether this is a glitch, or whether the infection failing to go away on its own is. [Testing Required: Reading through the game's source it seems to be scripted to happen after two in game days.]
  • Sometimes the player will receive the infection instantly upon becoming covered in blood, this could be the result of the 25% chance being triggered instantly, or an unintentional effect.
