War and Plague. Just two horsemen of the apocalypse but never really far away from each other. Where armies march, disease usually follows. From the earliest records of time to modern day, epidemics and contagious diseases are the cause of uncountable deaths. Pandemics like the Spanish Flu or the Bubonic Plague killed millions of people around the world. To survive, mankind had resort to quarantines and plague houses, and put its trust to physicians and the evolution of modern medicine.
