The Blue Flu

Currently in a dormant state, it is likely that you will never know the true nature of the mutated virus that is now hiding out in your cells. Manifesting in a way much closer to the traditional flu, those that recover see no other indication that the risk of contagion remains, however a fertility test will reveal that they have become sterile. A silent harbinger of doom, those that come in contact with your bodily fluids remain at risk of spreading this sleeping virus to others. Although not caused by FEV exposure, it was an important precursor and was widely believed to have been created by the pre-war government.

Considered a relatively minor flu, raise the Difficulty of all Perception and Intelligence checks by one for a number of days equal to fifteen minus your Endurance attribute. You may further attempt an Endurance + Survival roll to reduce symptoms, removing one more day for each success you achieve, (max 5).
