The Black Death was a devastating global pandemic of bubonic plague that originated in Asia and spread to Europe in the mid-1300s, killing approximately 50 million people in Europe. It spread through contact with infected rats and their fleas, which would bite humans and transmit the disease. Sailing ships provided an ideal environment for the spread of infected rats and fleas between ports. Physicians at the time did not understand the disease and relied on ineffective and sometimes dangerous treatments. The pandemic eventually declined due to the practice of quarantining the infected and improved hygiene and medical practices.

The Black Death
The Black Death arrived in Europe in 1347 from Central Asia, carried by fleas on black rats. Over the next three years, it killed an estimated 25-50 million people across Europe, anywhere from one-third to one-half of the total population. Transmitted through flea bites and respiratory droplets, the plague's symptoms included fever, chills, vomiting and the appearance of swollen and infected lymph nodes. While it left devastating social, economic and political impacts, some areas fared better through early quarantines and isolation practices. The Black Death remained a threat in Europe for centuries and still occurs sporadically today.
Zoonosis history and bacterial zoonotic diseases
Zoonoses are diseases that can be transmitted between animals and humans. Some key points:
- Zoonoses have affected humans throughout history, with examples like the bubonic plague in the 14th century killing one third of Europe's population.
- World Zoonoses Day is celebrated annually on July 6th in recognition of Louis Pasteur developing the first vaccine against rabies in 1885.
- At-risk groups like the immunocompromised, elderly, and those with HIV/AIDS are more susceptible to severe illness from zoonotic infections involving bacteria like Salmonella, Campylobacter, and parasites like Toxoplasma and Cryptosporidium.

Black death
The Black Death was a devastating pandemic that originated in Asia and spread to Europe between 1346-1353, killing an estimated 75-200 million people. It was caused by the bacterium Yersinia pestis, which was often carried by fleas on rats and spread to humans. There were three main forms: bubonic plague caused swollen lymph nodes, pneumonic plague led to lung infection, and septicemic plague caused blood poisoning. In the absence of modern medicine, treatments were ineffective and mortality rates were extremely high. The Black Death had profound social and economic impacts on medieval Europe. While rare, plague still occurs today but modern sanitation and antibiotics have controlled its spread.
Plagues And People by: Geetha Mahendran
Plagues have had a significant impact on human populations throughout history. Parasites spread disease which often killed large portions of populations that lacked immunity. This led to societal changes as populations developed immunities or declined. The rise of trade networks helped spread plagues to new populations without prior exposure, like the Black Death in Europe. The colonization of the Americas also introduced new diseases, devastating indigenous populations. Advances like vaccines have helped control plagues, but the relationship between parasites and people remains an ongoing factor in human development.
History of epidemics of plague
The document summarizes the history of three major plague pandemics:
- The Justinian Plague from 541-544 CE originated in Africa and killed over a third of Constantinople's population, contributing to the demise of the Byzantine Empire.
- The "Black Death" pandemic from 1347-1352 CE was the most devastating, killing an estimated 30-60% of Europe's population.
- The third pandemic lasted from 1894-1959, killing over 15 million people mostly in India, before being controlled through public health measures and antibiotics. Major outbreaks occurred in Hong Kong, Australia and India during this period.
14.4 a century of turmoil
The document summarizes the Great Western Schism, early reformers like John Wycliffe and Jan Huss, the Black Death plague pandemic of 1347-1350, and the resulting social turmoil in Europe. The plague is believed to have killed between 1/3 to 2/3 of Europe's population and led to widespread fear, religious fanaticism, and breakdown of social order as people struggled to understand and respond to the catastrophe.
Unit 6.1 black death
The Black Death plague arrived in Europe in 1347 from Central Asia, carried by fleas on black rats. Over the next three years, it killed almost half of Europe's population. The plague spread quickly through towns and villages across England between 1348-1349 due to filthy living conditions that supported rat populations. Medieval people did not understand germ theory and employed ineffective cures like applying frogs to boils caused by plague. By 1350, approximately 2.5 million people in Britain had died from the pandemic.

This document provides an overview of medicine in the Middle Ages and Renaissance. It discusses that during the Middle Ages, medical knowledge declined as Roman and Greek works were lost. Disease was often attributed to religious causes, and medical practices were limited. The Renaissance brought revivals in learning, anatomy, and the scientific method. Figures like Vesalius, Harvey, and Paracelsus advanced understandings of anatomy and circulation through observations and experimentation, moving away from past authorities like Galen. Overall, medicine transitioned from being primarily religiously-based to increasingly scientific and evidence-driven over these eras.

THE BLACK DEATH
The Black Death plague arrived in Europe from Central Asia in 1347 and killed almost half of Europe's population over the next three years. It likely arrived via infected rat fleas on merchant ships sailing from the Black Sea to Italy. The plague spread quickly through England between 1348-1350, infecting nearly all of Britain and killing around 2.5 million people. Medieval towns lacked sanitation, providing ideal conditions for rats carrying fleas infected with the plague bacteria to thrive.

Black plague
The Black Plague, also known as the bubonic plague or Black Death, was caused by the Yersinia pestis bacteria which infected fleas. These fleas would bite rats, dogs, humans and other animals, spreading the plague. Symptoms started as headaches, fever and vomiting before progressing to coughing up blood, respiratory failure and death. It killed 25 million people in Europe, approximately one-third of the population at the time. Doctors treating patients wore masks and long robes to avoid infection, which led to the costume tradition of Halloween masks.
The Plague
The Black Death plague of the 14th century was caused by bacteria found in rodents in Central Asia. It spread along trade routes, killing an estimated 20-40 million people in Europe, Asia, and Africa between 1347-1400. Symptoms included fever, chills, and swollen lymph nodes. Mongol armies besieging a Crimean city used infected corpses to spread the plague to Europe, where it devastated populations and economies and ended the feudal system due to labor shortages.

The Black Death
The Black Death was a devastating pandemic that originated in China in the 1330s and killed an estimated 30-60% of Europe's population by the late 1340s. Caused by the bacterium Yersinia pestis, it spread rapidly through trade routes and infected populations with little immunity. There were three main forms: bubonic, pneumonic, and septicemic plague. Factors like poor sanitation, war, and famine exacerbated its spread. It disappeared in the late 19th century due to improved hygiene, the spread of the more resistant brown rat replacing the black rat, and the bacterium slowly dying out in human hosts.
Tetanus
The document discusses three diseases: brucellosis, tetanus, and plague. It describes the causative agents, symptoms, modes of transmission, populations at risk, and methods of prevention and control for each disease. Brucellosis is caused by Brucella bacteria and transmitted from animals to humans. Tetanus is caused by Clostridium tetani bacteria entering the body through wounds. Plague is caused by Yersinia pestis bacteria and usually involves transmission from infected rodents to humans via flea bites.
Renaissance medicine by TriAngels (medical group) history of medicine
During the Renaissance period from 1400 to 1700 CE, there was a revival of learning in Europe with new ideas spreading due to the printing press. Knowledge of anatomy and medicine grew, aided by the study of ancient Greek and Roman ideas as well as discoveries from the New World. However, doctors were still unable to cure many diseases and their understanding of germ theory and treatment was limited. Public health measures to address issues like waste and hygiene were also lacking. While some trained physicians emerged, most people still relied on country doctors, barber-surgeons, apothecaries and quacks with little medical education for their healthcare needs.
Cholera
1. Assess the patient's level of dehydration by checking vital signs, hydration status, and symptoms.
2. For severe dehydration, begin intravenous rehydration then transition to oral rehydration solution once hydration is improved.
3. Continue giving oral rehydration solution along with zinc supplementation for children under 5.
4. Monitor the patient's hydration status and provide antibiotic treatment. Discharge once hydration is fully restored.

Black Death.pptx
- 1. Black Death
- 3. What is it • The Black Death was a devastating global epidemic of bubonic plague that struck Europe and Asia in the mid-1300s. • It would kill approximately 50 million people in Europe—almost one- third of the continent’s population.
- 4. How did it spread • The bubonic plague spreads through contact with body fluids. • Fleas bit infected animals, like rats, and then bit humans, infecting them with the disease. • “Plague pneumonia" • Spreading person to person via coughing or sneezing. • Sailing ships provided ideal breeding ground for the Plague: • Sailors were living in cramped quarters, and rats and mice were a common sight on ships, as were the fleas that lived on them. At each port, some of the rats left the ships with the cargo, and others hopped on board.
- 6. Symptoms of the infected
- 8. How do you treat it • Physicians relied on crude and unsophisticated techniques such as bloodletting and boil-lancing (practices that were dangerous as well as unsanitary) and superstitious practices such as burning aromatic herbs and bathing in rosewater or vinegar. • Meanwhile, in a panic, healthy people did all they could to avoid the sick. Doctors refused to see patients; priests refused to administer last rites; and shopkeepers closed their stores. Many people fled the cities for the countryside, but even there they could not escape the disease: It affected cows, sheep, goats, pigs and chickens as well as people.
- 11. How did it end • The eventual weakening of the pandemic was likely due to the practice of quarantining infected people that originated in Venice in the 15th century and is with us to this day. • Improved sanitation, personal hygiene, and medical practices also played a role in ultimately slowing the plague’s terror march.
