(4 point Flaw) (Vampire)
Your blood carries a lethal and highly contagious disease. The disease can be anything from rabies to HIV, and Kindred who drink your blood have a 10 percent chance of becoming a carrier as well. You must spend an extra blood point each night on awakening, or you will begin manifesting symptoms of the disease (increased chance to frenzy for rabies, reduced soak rolls for HIV, etc.).
