Bubonic Plague; 250 million deaths

Bubonic plague is the best known manifestation of the bacterial disease plague, caused by the Gram-negative bacterium Yersinia pestis (formerly known as Pasteurella pestis). It belongs to the family Enterobacteriaceae. The term "bubonic plague" was often used synonymously for plague, but it does in fact refer specifically to an infection that enters through the skin and travels through the lymphatics, as is often seen in flea-borne infections. Bubonic plague kills about half of infected patients in 3–7 days without treatment, and may be the Black Death that swept through Europe in the 1340s, killing tens of millions.

This disease outbreak was mainly caused by fleas and rodents infected with Xenopsylla cheopsis. Humans were infected after being bitten by an affected rodent.

  1. Each year, there are approximately 73,000 cases of E. Coli. This number may seem low in comparison to other infections, but in knowing how preventable it is; it is a big number. After reading through your website, it is clear that your organization has the same passion for E. Coli awareness, as Disease.com. Here, at Disease.com (a non profit website dedicated to the preventions and treatments of diseases) we realize how important establishing awareness is. That is why we have worked with several elite non profit organizations in the past. If you could, please list us as a resource or host our social book mark button, it would be much appreciated. Together, we can turn 73,000 into 0.If you want more information on that please email me back with the subject line as your URL.
