Diseases now come in '''stages'''. When a character is hit by an attack that causes disease (or exposed to some disease-producing effect), they must make a Fortitude save or else immediately enter Stage 1 of the disease. Multiple failed saves do not advance the character further in the disease progression. Each disease has different effects described for each of its stages and the effects are cumulative between stages.
Diseases also have a '''cycle''', which is how often the character must make a new Fortitude save to see if they improve or advance further with the disease. These Fortitude saves are taken at the first initial disease saving throw DC + the current stage the character is in. As they advance in the disease, it becomes harder to cure. A success means the disease does not advance for that cycle. A success by 5 or more means that it improves by 1 Stage. A failure means that the disease advances 1 stage. Bed rest reduces the DC by 2 and a [[SRD:Heal|heal]] check can be substituted for the saving throw in the case of long-term care.
Like the original rules, diseases can be caused by Contact, Ingestion, Inhalation, or Injury. Any disease can be caused by injury if it is carried by a monster, but otherwise, the listed infection type is the only way the disease can spread.
Generally, the base save DC for a disease should be 10 7 + 1/2 the monster's CR + its Constitution modifier. If the creature does not have a Constitution score, use its Charisma modifier instead.
