Bubonic Plague 1411 HOW CAN YOU HIDE AN EPIDEMIC? PERHAPS IT IS EASY: 1. Start with an unknown genus of bacteria. 2. Behave as a stealth pathogen that is difficult to detect or isolate. 3. Maintain a large and diverse pet and wildlife reservoir in nature. 4. Facilitate transmission through multiple vectors and by other means. BARTONELLA, HIV, PCR AND VASOPROLIFERATIVE DISEASE!
