Diseases are a type of condition in Fallout 76.

Causes and effectsEdit

Fo76 Disease icon

When the player character consumes unclean food and liquid, there is a chance of acquiring a disease. Being attacked by diseased creatures and sleeping on floor mattresses can also cause disease. Eating uncooked meat and drinking dirty water has the highest risks for disease.

Diseases cause a variety of effects including increased damage and needs, such as hunger.

As of patch, the player character must be level 15 or higher to acquire a disease.


Diseases can be avoided by cooking food, eating pre-War packaged food, and drinking boiled or purified water. Sleeping on raised mattresses and avoiding physical contact with diseased creatures will also avoid disease.

Maintaining a character's food and water needs each increases resistance of disease by 25%, even more (35%) with the perk Rejuvenated. Taking antibiotics also temporarily increases disease resistance, but using RadAway will temporarily reduce disease resistance by 50%. The perks Iron Stomach and Thirst Quencher greatly reduce the chance of disease from consumed food and liquid, respectively, while the perk Vaccinated protects against diseased creatures.


Diseases are time-limited and will expire. They can be cured prior to their expiration with disease cures or antibiotics. Alternatively, drinking from a sulfur water fountain (one is located at a white gazebo near the Whitespring golf club) will cure a disease.

Intentional diseasesEdit

Intentionally catching diseases is useful with the Plague Walker mutation or attempting to complete the challenge for acquiring all diseases. Note that similar to mutations, diseases have a 30 minute cooldown for catching another disease, or 45 minutes for the same disease. Leaving the server resets this cooldown so that another disease can be immediately obtained upon joining a different server.
