Plent fever is a horrible disease that is spread through unsanitary conditions. When plents eat things with feces on them, they can get infected with plent fever. Its effects are: weakness, stomach pains, headache, chills, delirium, confusion, loss of appetite, vomiting, and of course a high fever. If left untreated, the infected plent can die. The insidious part about it is that it can stay dormant in a plent's systems for days without showing symptoms, thus spreading itself in the plents droppings. This disease is common throughout Sagan 4 and only infects mobile plents.
