Question

in the 14th centry in europe, the bubonic plague killed approximately one third of the population. Bubonic plague is caused by bacteria Yersinia pestis, which is spread by an insect vector carried by rats and other rodents. This disease can be spread to other animals besides humans. How is control of a disease such as bubonic plague complicated by the fact that it spreads across multiple animal species?

Answer 1

once you control one animal species it might have spread to other species already.

Answer 2

Answer:

The fact that a disease spreads through multiple animal species creates problems in its eradication since it is necessary to look for more than one strategy for disease control, additionally this causes the disease to expand at a more dizzying pace.This situation also causes the disease to expand geographically and increases the likelihood of infection in humans.
