Black Death

Introduction

Black Death was an epidemic that spread to Western Europe and Britain in 1347-50. It caused havoc because about one-third of the European population died from the disease. The plague was weather related, because temperature and humidity were associated with multiplication of the carrier insects—Oriental rat fleas—which transmitted the bacteria from rats to human beings. After a flea fed on blood from the skin of an infected rodent, the ingested plague bacteria (Yersinia pestis) multiplied in the flea's upper digestive tract, blocking the flea's stomach. When the flea fed again on a human or another rodent, the blockage caused the freshly ingested blood to be regurgitated back into the bite, along with the plague bacteria.

The infected human beings then carried these bacteria throughout their circulatory system. Cartwright (pp. 56-61) mentions the first signs of illness in humans appeared within about a week. The plague caused a high fever, and the lymph nodes throughout the body, especially those in the groin and the thigh, become swollen and extremely painful. The enlarged lymph nodes, called buboes, become filled with pus, and the disease spread through the infected bloodstream and the lymphatic system. The disease also caused spots on the skin that were initially red and then turned black, which some believe inspired the name Black Death. In 60-90 percent of untreated victims, the inflection became overwhelming, leading to death within a few days (Cartwright, pp. 56-61). This paper discusses Black Death in a concise and comprehensive way.

Black Death: A Discussion

Pneumonic plague is caused by the same bacteria, as in the case of bubonic and septicemic plague. It is acquired when plague bacilli, discharged into the atmosphere via infected droplets during coughing or heavy breathing, is inhaled by the victim. This form of plague is highly contagious; the largest epidemic occurred in Manchuria in 1910 and 1911, when 60,000 people died.

This urban community plague, originating in China, first spread with the movement of the Mongol armies and traders. In the beginning, Caffa—a Crimean port on the Black Sea—was afflicted by the disease in Europe in 1346. The Italian traders from Genoa brought the disease to the western European soil, from where sea traders and caravans carried the disease to France, Germany, Denmark, Poland, Finland, and Greenland. From its central Asian foci it diffused southward to Africa, eastward to China, and northwestward to Russia. Within three years, the disease reached the British Isles, and the first afflicted ports were Bristol and Southampton (Platt, pp. 34-41).

The impact of Black Death in England was not only immediate; it also lasted for at least two centuries. About half of the English population died during the bubonic form of plague that first appeared in the summer of 1348 in England. The bacteria also mutated into a dreadful pneumonic form in the winter (Platt, pp. 34-41), and London was attacked by both pneumonic and bubonic plague. The Parliament was prorogued; three archbishops of Canterbury died in quick succession.
