is the bubonic plague a bacteria or virus?
bacteria
the three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. bubonic plague is mainly spread by infected fleas from small animals. it may also result from exposure to the body fluids from a dead plague-infected animal. in the bubonic form of plague, the bacteria enter through the skin through a flea bite and travel via the lymphatic vessels to a lymph node, causing it to swell. diagnosis is made by finding the bacteria in the blood, sputum, or fluid from lymph nodes.

in addition to arguing that the rat population was insufficient to account for a bubonic plague pandemic, sceptics of the bubonic plague theory point out that the symptoms of the black death are not unique (and arguably in some accounts may differ from bubonic plague); that transference via fleas in goods was likely to be of marginal significance; and that the dna results may be flawed and might not have been repeated elsewhere or were not replicable at all, despite extensive samples from other mass graves. other arguments include the lack of accounts of the death of rats before outbreaks of plague between the 14th and 17th centuries; temperatures that are too cold in northern europe for the survival of fleas; that, despite primitive transport systems, the spread of the black death was much faster than that of modern bubonic plague; that mortality rates of the black death appear to be very high; that, while modern bubonic plague is largely endemic as a rural disease, the black death indiscriminately struck urban and rural areas; and that the pattern of the black death, with major outbreaks in the same areas separated by 5 to 15 years, differs from modern bubonic plague—which often becomes endemic for decades with annual flare-ups.
