They led to important developments in infectious disease control-many of which we still use. The plague epidemics of the past are a reminder of the social as well as medical impact of epidemics. The plague resurfaced roughly every 10 years from 1348 to 166540 outbreaks in just over 300 years. Using techniques such as genome mapping, scientists have been able to identify the exact strains of bubonic plague that they encounter and their origins, making it easier to track the spread of epidemics. Genetic evidence of the Yersinia pestis bacterium in several plague burial grounds from 1348–1590, has also confirmed that the Black Death was, in most cases, bubonic plague. London never really caught a break after the Black Death. In 2017 the deadliest outbreak in modern times killed 170 people and infected thousands on the island. But drug resistant forms of the bacteria were identified on the island of Madagascar in 1995. With modern antibiotics the mortality rate has fallen from over 60% to 11%. For example, Edgar Allan Poe s short story The Masque of the Red Death (1842) is set in an unnamed country during a fictional plague that shares many things. The Black Death appears in some modern literature and media, used as a subject or a setting. A few small pockets of infection remain around the world, particularly in central Asia where the disease is endemic. With such clothing, doctors in Rome tried to protect themselves from the Black Death (1656). The fleas also infested clothing and could be carried to other locations in that way.īy the 1930s plague epidemics were a thing of the past. Did the Black Death shape the human genome Study challenges bold claim. When the rats died the fleas moved onto human hosts. Known as house rats or ship rats, black rats liked to live in close proximity to humans. The fleas were transported around the world overland and on ships by black rats. In 1898 Paul Louis Somond established the mechanism for transmission was via fleas, which transferred bacteria from infected hosts to the non-infected through their bites. French-Swiss bacteriologist Alexandre Yersin isolated the bacterium that caused the disease in 1897, and it was named Yersinia pestis after him. From Hong Kong it entered the ports of India, where at least 12 million people died over 20 years.īy the end of the 1800s, developments in bacteriology and infection control meant that medical researchers were able to observe and investigate the disease in detail for the first time.Ī team of European scientists was sent to colonial Hong Kong in the 1890s to study the epidemic. Between 18 there were over 24,000 cases in Hong Kong. The third pandemic wave began in Southern China in 1865, spreading south and west. Outbreaks of plague continued in Asia throughout the 1800s.
