Zoonotic Disease: Plague Study

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

The roots of this fearsome plague are very chilling to think about knowing that a mere flea can be the cause of the bubonic plagues epidemic. The more specific medical or scientific term for this disease is Yersinia Pestis. This was named after the doctor, Alexandre Yersin, who isolated the bacteria in 1894 during the pandemic that began in China in the 1860’s. The earliest traces of Y Pestis can be found all the way back to the Gobi Desert of Mongolia in the 1320’s. The cause of the sudden eruption is yet to be solved but the earliest major toll it has taken in our history books is in China in the 1330’s during the expansion of trade in the middle and high

Plagues are basically diseases that meant to kill all humans that came in contact with. Talking about famous plagues, it reminds me of the black plague also called the bubonic plague in the 1300s that took the lives of millions in Europe, the great plague of London that was caused by some kind of rat infestation infecting the food and the plague in China's Yunnan province that also spread to India also killing millions of people. I am not sure what other plagues I have missed as I may not have heard about them. Several research questions that capture the most interests in my topic are as follows (according to table 1.1):

The prevalence of disease in the thirteenth century was very common in Europe,and Africa, later on spread to parts of Asia. Currently the bubonic is not that common but is still infecting a small portion of the earth. The Bubonic Plague is an infectious disease caused by the bacteria Yersinia Pestis, a zoonotic bacteria, usually found in small animals and their fleas. It is transmitted between animals and humans by the bite of infected fleas, direct contact, inhalation and rarely, ingestion of infective materials.

The Bubonic Plagues a highly lethal infection caused by the microbe Yersinia pestis. This plague is most commonly associated with the plague of the 14th century, when it wiped out nearly half of the entire European population. The Bubonic Plague spread rapidly throughout Europe and was an often fatal illness, characterized by enlarged lymph nodes with pus filled buboes, gangrene, septicemia, and severe lung infections, followed by the quick onslaught of death. The Black Plague is the worst natural disaster in European History. The plagues devastation impacted all aspects of European life and was the turning point from medieval to modern Europe. The incidence and virulence of the plague decreased over the years and became limited to certain areas by the end of the 20th century. However, the black plague has recently re-emerged around the world. The expanded knowledge from genetic research has introduced the threat of multidrug resistance and a modern day pandemic of the “Black Death.”

In the fourteenth century, there was a plague that spread quickly, called the Black Death, or the bubonic plague; it killed 20-30 billion people in Europe in the 14th century (“The black plague…”). In China, it killed 12 million people in the 19th century and slowly traveled to America with the help of rats on ships from other countries. The bubonic plague was found in rodents, like rats, and also in fleas. If a person was bitten by an animal with the virus, then they would contract the bubonic plague. Thanks to better working conditions, antibiotics, and better sanitation, there were only 2,118 cases of the bubonic plague in 2003 worldwide. Only one in every seven people died (“The

The bacteria found in the Black Plague is known as Yersinia pestis that is a bipolar and plump, lightly-staining, coccobacillus. Remaining a dangerous threat even today as well as what was previously stated that it is a plausible agent for bioterrorism. And as stated, areas such as America, Asia, and Africa are foci endemic areas. Where wild rodents, such as squirrels and rats, are the sustenance pushing for the spread and infection of the disease. The transmission being from animal-to-animal through fleas and infection to humans through contact or bites. Instances of human-to-human infection are uncommon except for the pneumonic plague, the disease caused by plague bacillus also known as Y pestis. The germ was named after Alexander Yersin who had discovered it in 1894 during a pandemic in China that started in1860. Causing numerous casualties by how fast and effective the disease was spreading, it had seemed that there was no end in

Plague is an infectious disease that affects rodents, other animals and humans caused by Yersinia pestis bacteria. Yersinia pestis is the causative agent of the Plague. It is a virulent pathogen causes painful, severe illness as well as death. “Yersinia pestis is a Gram-negative, bipolar-staining coccobacillus member of the Enterobacteriaceae family, and is an obligate intracellular pathogen that must be contained

The first problem I'm going to be talking about is what happened in the past prior 1900’s. In the course of just a few months, 60 percent of Florence’s population died from the Plague and probably the same proportion in Siena(Benedictow). The great of Plague London In 1665, over 250 of Mompesson’s flock had died, possibly one-third of the population of Eyam(Dobson08). The Plague has killed so many people in the last past prior 1900’s that people are really scared now. In the present 1900’s there was about 121 cases and 113 deaths(Reasearches08). The case has the mortality rate approximately of 50%-60% pneumonic Plague(“Plague”). In India 1994 the disease has had about

The Black Plague was caused by the yersinia pestis found in rodents. The origins of the plague can be traced back to the Gobi Desert in Mongolia around the 1320’s. Soon after the plague struck China, India Persia,

The bacteria Yersinia Pestis is the cause of the black plague. Y. Pestis was discovered by Alexandre Yersin in 1849. The plague was the cause of one of the world's most horrific epidemics in the entire world. The plague is an infectious disease that first appeared in 1347 in China and made its way to Asia and then the Black Sea. The Black Plague has caused death to about 75 million lives. The plague is a deadly bacterial infection that can cause death if left untreated. The plague got its name the “Black Death” due to the fact that this disease caused black boils on the skin and that its victims were always on the verge of death when seen. The Plague would then soon arrive in Europe

The “plague” is known as the “Yersinia pestis” bacteria, which is a rare zoonotic disease. These diseases are spread from animal to human (Newquist 239, Adamloakun M.D. 718). The bacterium lives in rodents such as rats and is carried by fleas (Newquist 238). When the fleas bite humans, the bacterium spreads.

plague in and of itself is a bacterium called yersinia pestis and is carried by rodents (Scogna).

It was believed in the middle ages that this disease was caused by poor hygiene, bad eating habits, corrupted humid air, and a lack of rest. Once a person was thought to be infected the doctors would move them to a non-infected area thinking that this would heal the persons illness instead this transported the disease even further than normal. In modern times we have made leaps and bounds to control this illness. One of the main problems of the plague is that it is not treatable until the victim gets tested and confirmed that the plague is the illness. Once that is done they will start receiving high doxycycline doses and many other types of antibiotics. The mortality rate for someone that is not treated is 50-90% compared to treated cases of 1-15%.

The outbreak of Yellow Fever started Luanda (Goldschmidt). Since then ten out of the eighteen provinces in Angola have been affected by the virus (Goldschmidt). As of December 2015, one thousand one hundred have been victimized of the virus, and one hundred and eighty-two people have died from the virus, as on average per year in a mixture of countries 60,000 people die from Yellow Fever (Goldschmidt). And it isn’t just in Angola and countries in Africa, from the epidemic in Angola and other countries surrounding Angola, it is starting to spread to
