How Did The Bubonic Plague Affect The Human Body

The Black Death was one of the most life-changing pandemics in history. It was first discovered 550 years later in the 1800s by Alexandre Yersin, a french biologist. In his honor, the plague was named Yersinia Pestis. The plague traveled in two major ways. Yersin discovered that it traveled by infected fleas; the flea would attempt to feed on a human or animal and would then regurgitate the disease into the new host, further spreading the illness. Urban areas across Europe were populous with rats, which were one of the main hosts of the plague. These rodents spread the Black Death throughout cities in days. The unaffected still were not safe if they did not come in contact with an infected flea or rat. The plague also traveled pneumonically, or through the air. It caused large boils full of blood and pus, which would pop and spread. Another symptom was coughing, which was one of the many ways of proliferation. The disease eventually spread throughout Europe and killed a third of it’s population. It’s wrath caused many shortages, loss in hope, riots, and even some good things, such as many changes in art, science, and education. Therefore, the Black Death was one of the most life-changing pandemics in history.

The Black Death, also known as the bubonic plague, was a disease that devastated Medieval Europe, between 1346 and 1352 it killed 45 million people, wiping out a third of Europe's population. Today, we know that there were many causes of the Black Death. Medieval towns had no system of drains, sewers or trash collections. In such slovenly conditions, germs could grow, and diseased rats could call these medieval towns their homes and infect the people who lived there. Many historians believed the plague originated in china and spread to other countries by trade routes. Infected people and/or infected rodents such as mice or black rats. The Black Death was caused by strains of the bubonic plague. The plague lived in fleas, and fleas lived on

75 to 200 million people died from the Bubonic Plague it was estimated about 2\3 of the European population died. Bubonic Plague hurts the Immune system by attacking an invading it. The only way to stop the Bubonic plague is by antibiotics and prescription drugs that destroy the virus. If not treated it will enter the bloodstream and attacks the lungs. Which could give the body Pneumonic plague which is deadly and the Pneumonic plague will give people hepatitis which will give the body fatigue and muscle weakness. The cells in the body system fights off bad pathogens. It keeps the body from getting infected with viruses and diseases like the flu. The Bubonic plague entered the Immune System by changing it form to disguise itself so it will let it in when it is in the Immune System. It attacks by shutting it down and kills cells inside. So the body cannot fight it off. Then it enters the bloodstream and without the immune system it cannot be stopped because the immune system fights off the virus. And without it fighting off viruses the body is prone to any diseases and viruses like the t cell which keeps the flu virus away from the body. And the Bubonic plague kills the t cell which now it is prone to the flu. And it also attacks the b cell which makes antibodies which helps the body become healthier and safer.

In the 14th century the Black Death engulfed Europe killing an estimated 50 million people. The pandemic is considered extraordinary because it did so in a matter of months. This disease was carried by fleas, the Bubonic Plague is caused by a bacteria called Yersinia pestis, found mainly in rodents, in this case in rats, and the fleas that feed on them.

What is the plague? The plague or referred to as the Black Death, according to the CDC (2015), “is a disease that affects humans and other mammals and caused by the Yersinia pestis bacteria. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague”. There are three categories of a plague. There is the bubonic plague, which is the most common form. With this form bacteria infects the lymph system and causes it to become inflamed. Symptoms of this type of plague are fever, headache, chills, and swollen and tender lymph nodes, which are called buboes. Then there is the Septicemic, which occurs when the bacteria multiply in the blood. Symptoms of this type of plague are fever, chills, extreme weakness, abdominal pain, shock, and possibly bleeding into the skin and other organs. Also, skin and other tissues may turn black and die, especially fingers, toes and the nose (CDC, 2015). Then there is the Pneumonic Plague, which is the most serious form of plague and occurs when Y. pestis bacteria infect the lungs and cause pneumonia (NIH, 2015). This is the only form of the plague that can be transmitted human to human. Symptoms of this form of the plague are ever, headache, weakness, and a rapidly

Why was the Bubonic Plague (Black Death) so Devastating to European Society? The Bubonic Plague, otherwise known as the Black Death, was a huge epidemic in the mid-1300s. It killed off about 20 million Europeans within 1348 and 1351and was thought to originate from China and move westwards through means of infected fleas and rats through shipping and trade (Document 1).

Bubonic Plague/ Black Death Topic Questions: ( The stuff in colors isn’t plagiarism) What was the Bubonic Plague? The bubonic Plague is a plague spread by infected fleas. The poisoned fleas feed on their hosts, then spit the blood back onto the wound on the animal (such as the rats that spread the Plague during the London Elizabethan Era).

The black death is believed to have began in central Asia in the mid-thirteen hundreds, and killed millions. After it spread across Asia it was then carried down the Silk Road reaching Crimea by 1343. Scientists believe that the plague was carried by fleas on rodents, such as rats, being normal passengers traveling on merchant ships across the Mediterranean. The fleas were believed to have bacteria called Yersinia pestis, which is commonly present in the flea population on ground rodents in certain areas such as Central Asia, Kurdistan, Western Asia, Northern India, and Uganda. Scientists believe that all three outbreaks of the epidemic began in China. The disease was devastating to the economy of Europe and Asia, making it hard for people to find employees, and forcing them to pay higher wages. The plague was supposedly

The cause of the Bubonic Plague was by a living host that transport from one animal to another animal, which is called a vector-borne illness. A Xenopsylla Cheopis, an oriental rat flea, was the vector. When the flea bites, the wound is injected by infected blood and the body’s natural response to inflammatory decreases. The bacteria travels using white blood cells to find the closes lymph node, then spreads and multiplies. Lymph nodes are important because they carry fluids, waste material and nutrients to body tissues and the bloodstream. If they swell up, they can’t filter out the bad bacteria in the body. In the first few days of catching the plague, a person experiences large swelling in the lymph nodes which causes the body immune to

Bubonic plague kills only half the people that get infected, but Septicemic and Pneumonic plague are more infectious and are always fatal. People usually refer to the plague as Black Death or Bubonic Plague. Black Death was coined because of the black swellings and eventual blackened skin from the hemorrhaging blood vessels. Bubonic Plague is usually the term that is spoken of, but it is Septicemic and Pneumonic Plagues that were responsible for the large amount of deaths. The plague continued to be a menace in later centuries.

Imagine going back in time to witness the Black Death that struggled Europe in the 14th century. The Black Death originated in China because China was huge on trading, eventually reaching Europe about 20 years later through trade routes. According to Source 1, the Black Death was a combination of three plagues: bubonic, killing cells and attacking the nervous system, forming black bumps appear on the body, pneumonic which causes a person to cough, spreading the plague and a high fever, causing the person to go in a coma, septicemic which goes directly in the bloodstream, causing a rash. Rats carried a bacterium called Yersinia pestis. Fleas bit rats, carrying the bacteria, then biting humans, causing the plague. Once the disease was contracted,

The causes of the Black Death – the flea, the rat, and the bacillus Yersinia pestis– have been labeled the “unholy trinity” (Boeckl). The flea is able to live in environmental conditions of about 74° Fahrenheit and 60% humidity (Ibid). Before the Black Death reached Europe, they were experiencing those same types of weather conditions. The rat flea, Xenopsylla cheopis and the human flea, Pulex irritans, are both capable of transmitting plague (Boeckl). Sometimes, an infected flea cannot ingest blood because Yersinia pestis obstructs its digestive tract. The blockage causes a flea to regurgitate into a bitten host rather than ingest the host’s blood, thereby infecting the host with plague (Boeckl). Unable to eat, the famished flea will bite with more frequency, accelerating the spread of plague. A flea can be carrying Yersinia pestis without it blocking the flea’s digestive tract, in which case the flea does not transmit plague when it bites a host. Also, Yersinia pestis can only enter a victim through a bite, as the bacilli cannot pass through intact skin (Gottfried).

The black death was a disease triggered by the bacteria Yersinia pestis. Yersinia pestis is a bacterium transmitted by rodents,

The Bubonic Plague and a variation called the septicemic plague was spread throughout Europe by oriental rats that carried infected fleas. Little is known to why the infection never seemed to affect the carrier rats. Infected fleas were being starved by the infection, so they began feasting upon the people they came into contact with. These fleas coming into contact with any human being would infect the human with the disease. These people were now carriers of the Bubonic plague or Black Death. These infected people would then spread the disease by coughing or coming into direct contact with another human being. However, this disease, since not being transmitted via rat would now be called the Pneumonic Plague. (www.insecta-inspecta.com).
