Spreading and Prevention
The Black Plague was spread from rats to fleas to humans or from direct animal content that was infected with it. It didn't usually spread from human to human, unless they became sick with pneumonia and it was spread from coughing and sneezing. But who would want to deal with any of that? Preventing is the best way to not have to deal with the Plague at all, and there are many ways areas are doing just this. Controlling the Plague in wild rodents is found to be too costly, so other ways of Plague prevention is managing the environment, having public health education, and preventative drug therapy. Reducing outbreaks is another very important factor. The requirements to reduce outbreaks are: treating pets for fleas, using insecticide to reduce the number of fleas, control rat population, and watch for Plague cases in rats/humans in the area.
