Diseases are dangerous pathogens that can negatively impact a Survivor or creatures. On a PvE server, the contraction of diseases is limited to members of the same Tribe. Wild creatures cannot contract diseases.
Types of Diseases
Swamp Fever is a disease that can be contracted by a Survivor or tamed Dodo either by being bitten by the Diseased Leech found in the swamps of the Ark or from an infected Survivor or creature. Swamp Fever persists after death until the Survivor levels up and can be cured with the Lesser Antidote. Swamp Fever reduces stats, lowers stamina regeneration, increases movement speed, decreases food, water, and oxygen consumption, puts a green cloud over the Survivor's head, and makes the Survivor cough periodically until cured.
