Smallpox is an acute contagious disease cause by the variola virus, a member of the poxvirus family. The only host of this disease is through human. It is transmitted through close contact. The name smallpox is derived from Latin word for “spotted” and then refers to the raised bumps that appear on the face and body of an infected person. There are two kinds of smallpox; Variola major and Variola minor. Variola major is the most severe one and most common smallpox with extensive rash and high fever. Both cause skin lesions though the symptoms of the Variola minor are considerably fatal. The symptoms of smallpox are as follows; high fever, fatigue, vomiting, headaches. In addition, a rash on the face, arms and legs and other parts of the body …show more content…
According to Linda Newson, “population size is critical for understanding the incidence of infection. Since endemic infections are characterized by latency and recurrence” . Here I will argue that highly dense population and slavery created conditions extremely favorable for the transmission of smallpox, and that it created huge impact on Spanish conquest. Did slavery and highly dense population increase in the spread of smallpox or it goes beyond these measures? The beginning of smallpox as a character illness is lost in ancient times. It is believed to have appeared in around 10,000BC, around the same time of the first agricultural settlement in northeastern Africa. “It appears conceivable that it spread from that point to India by method of aged Egyptian dealers. The earliest evidence of skin lesions resembling those of smallpox is found on faces of mummies from the time of the 18th and 20th Egyptian Dynasties (1570–1085 BC). Unknown in the New World, smallpox was introduced by the Spanish and Portuguese conquistadors.” (Edward …show more content…
Many of the Aztecs had fallen ill or died from smallpox, which was said to have brought over by slave abroad Cortes’s ship. Certain conditions in Mexico made are worse for the high death rate from this disease. The spread of the smallpox appeared to have been aggravated by the extreme climatic conditions of the time and by the poor living conditions and harsh treatment by the native people. The Mexican natives were treated virtually as slaves, they were poorly fed and clothed and were greatly overworked on farms as laborers. This harsh treatment appears to have left them very exposed to the epidemic
... The plague was brought over by the Spanish who where immune to the disease, but the Aztecs weren't so lucky. Many where killed over the course of seventy days, including the new King Cuitlahucs (92). Obviously this had a dramatic impact because they lost their leader. Those that remained where very weak with a milder form of the disease (93). Obviously this affected their strength to fight.
In closing, the variola virus affected a great amount in that era including, military strategy, trade, and native populations. Elizabeth A. Fenn’s book Pox Americana: The Great Smallpox Epidemic of 1775-82 sheds light on a significant aspect of that era that had not been given proper credence beforehand. She also illuminated the effect of smallpox when it came to race and social status. With regard to race, smallpox decimated much of the non European populations partly because of their lack of an innate immunity to that virus and Europeans lack of regard for those of a different race. Fenn’s argument on social status showed how the poorer strata’s of society suffered more severely from the variola virus because of their lack of finances to get inoculated; thus, the poor often suffered a worse strain of the virus which often lead to death.
The spread of disease through trade nearly diminished the whole population (Doc 2, Doc 4, & Doc 6). According to Geoffrey Cowley and Dinesh D’Souza, the Europeans who crossed the Atlantic have each battled an illness resulting in the Native Americans later becoming immunologically defenseless (Doc 2 & Doc 6). The Native population of Central Mexico in 1519 began at 25.3 million, but in 1605, the population drastically dropped to 1 million (Doc 4). The vast majority of Indian casualties were not due to hard labor nor deliberate destruction but occurred due to the contagious diseases spread by the Europeans; smallpox, measles, influenza, and typhus (Doc 6). The Indians, having not developed any immunity to the unfamiliar illnesses transmitted by the Europeans, quickly began to diminish, leaving behind a small population. A document that would have been useful would’ve be one from a women’s view on the economy. Men wrote all documents so this additional document could have provided information about how the Columbian Exchange impacted the women population and their views on
The Columbian exchange was the widespread transfer of various products such as animals, plants, and culture between the Americas and Europe. Though most likely unintentional, the byproduct that had the largest impact from this exchange between the old and new world was communicable diseases. Europeans and other immigrants brought a host of diseases with them to America, which killed as much as ninety percent of the native population. Epidemics ravaged both native and nonnative populations of the new world destroying civilizations. The source of these epidemics were due to low resistance, poor sanitation, and inadequate medical knowledge- “more die of the practitioner than of the natural course of the disease (Duffy).” These diseases of the new world posed a serious
Smallpox according to Feen took its toll on American’s as well as those of the colonist and British soldiers. One other item of interest I found in the introduction was the map of how the virus moved itself across North America. The virus from what I can see only need a host to travel. After closer examination you can see that they virus followed the routes of the soldiers or that of other militia as they made their way through parts of North America and Canada. Once it started there seemed to be no stopping i...
Smallpox has been believed to be a prominent killer for thousands of years. Before 900 AD smallpox and measles were easily interchangeable to many physicians. These two diseases possessed similar symptoms, such as fevers and rashes, making it very difficult to distinguish between them. It was not until the Persian physician, Rhazes Ar-Raz Abmiz, that measles and smallpox were able to be clinically distinguished in 900 AD. Much later in 1751, Thomas Sydenham found further differentiating characteristics between the two diseases(Aufderheide, 202). Through the years, with its many outbreaks in varying areas across the planet, smallpox claimed millions of victims. Many rulers and soldiers were killed by this incredibly infectious disease. To prevent and hopefully stop the increasing numbers of deaths due to smallpox, many physicians slaved away to invent and find a cure for this disease. The first effective method of prevention was called variolation. Variolation was later modified and improved with vaccinations(Hopkins, 15). Today wild smallpox is no longer a risk. The last natural case of smallpox was reported in Somalia in 1977. While the last reported death due to smallpox was reported to be a year later in the UK(McNeil, 165). Smallpox is not completely out of the picture. After the 2001 attacks with anthrax, a strong paranoia of smallpox being used as another possible mean of bioterrorism has arisen(Oldstone, 32).
The introduction of smallpox led to the death of countless native peoples, an estimated 90%. In addition to its initial impact, smallpox created disorder among the natives as their leaders fell ill, leaving them vulnerable to attack. Arguably the most famous incident of this was in the Inca, where the death of an emperor created civil war, leaving the empire, which eventually fell to Pizarro, weak and fragile by the time the conflict ended. On the other hand, the Europeans came out virtually unscathed. Though syphilis, the only significant disease to travel back with the Western sailors, did wreak some havoc of its own in Europe, its impacts were hardly comparable to the mass deaths caused by its counterparts.
Imagine it, you’re a Native American in 1763. Men come on your land handing out blankets ,after a day of using the blanket you begin to get a fever. Two days later you begin to receive a rash, bumps filled with pus all across your body, sound familiar?You didn’t know then but we know now that this was smallpox,but what is smallpox? How did it start? Is the virus still active? What is its history? No matter what your question is (In regarding to smallpox) it will be answered today in my essay.
Small Pox is a contagious and possibly fatal virus that has been thought to be around since 10,000 B.C. Smallpox has killed 1 in 3 people infected. Nearly one of ten of the population had been wiped out because of smallpox. The virus was caused by the Variola virus and can only be transmitted by people. Small pox is characterized as a skin rash with vesicles containing fluid that then enlarge to contain pus. Small pox infects a person through the mouth and nose, and then it grows in the mucous membranes. “The last case of Small Pox in the United States was in 1949” (Smallpox Disease Overview). The last case of smallpox in the world was in 1977 in Somalia. An infected person can infect up to 2 to 5 other people but in order for the people to be infected they have to already have the rash and fever.
The Bubonic plague, scientifically named “Yersinia pestis”, widely known as “Black Death”, was an infectious disease, which, during 1347-1352, wiped out about a third of the world’s population, roughly 25 million people. A similarly deadly disease, Smallpox, scientifically named “Variola”, was a virus that caused about 300 million deaths in the 20th century. Both were massively destructive plagues that wreaked havoc wherever they were found. Smallpox was spread by contact with the infected person or clothing that has the virus on it. It is also airborne, which makes Smallpox deadlier.
There are two clinical forms of smallpox: Variola major and minor. Variola major is the most common and severe form. There are four types of Variola minor: Ordinary, modified, malignant, and hemorrhagic. Ordinary is the most common form, and its case-fatality rate is near 30%. Modified is a milder form and smallpox is rarely fatal in this case. Malignant smallpox’s fatality rate, however, is near 97%, and Hemorrhagic is roughly at 100%. Variola minor is less common and less severe than its counterpart. However, if a person survives this form, they have lifelong immunity against...
The origin of the disease was lost in early history, but smallpox was a disease that dates back to ancient times that did not discriminate against anyone, affecting all levels of society. It conquered kings, queens, emperors, and attacked the lower classes as well. It is spread by physical contact and begins by invading the body through the lungs, spreads throughout the bloodstream, infects the organs, and finally leaves a terrible rash on the skin. A person who has smallpox was typically distinguished by a fever, headache, and vomiting. A pink rash appears after a few days and the hives grow until they eventually dry up and leave a sunken scar. Unfortunately, once the infection has occurred in, there was no effective treatment to cure the disease and over 30% of the cases were fatal, making smallpox the most
This is a disease that only affects humans.This disease is a serious, highly contagious, and often life-threatening infection marked by a rash of round pox (blisters) on the face, arms, and legs. It is caused by the Variola virus. The last case of smallpox in the United States was in 1949. n addition to flu-like symptoms, patients also experience a rash that appears first on the face, hands and forearms, and then later appears on the trunk. People may experience in areas in the back or muscles, rashes, small bump, blister, scab, or scar fever, malaise, or chills, headache or vomiting. Rashes and blisters are the most visible symptoms.The virus starts in the lungs. From there, the virus invades the bloodstream and spreads to the skin, intestines , lungs, kidneys, and brain. The virus activity in the skin cells creates a rash that starts as macules. After this, vesicles form. Then, pustules appear about 12-17 days after a person becomes infected. Survivors of smallpox often have severely deformed skin from the pustules. The variola virus causes Smallpox. There are two forms of the virus. The more dangerous form, variola major, led to smallpox disease that killed about 30% of people who were infected. Variola minor caused a less deadly type that killed about 1% of those who got it. There's no treatment or cure for smallpox. A vaccine can prevent it. But the vaccine's side
Smallpox is caused by the variola virus and is a contagious disfiguring and often deadly disease that has no existing cure or treatment. It was eradicated worldwide in 1980 by a global immunization campaign. Samples of the virus has been kept for research purposes.
“Smallpox is a viral infection caused by a virus known as the Variola virus that has been in existence for over 3000 years”. The first outbreak known was in the western area. With that said people should know about the way it is transmitted, what the treatment is and the vaccine for it and is it still needed today, how is it detected and the symptoms. To begin, smallpox is transmitted from contact with someone how has the disease. Most of the time just long, face to face contact with someone how has it is why smallpox’s spreads from one person to another. Smallpox can also be transmitted through the contact of body fluids or contaminated object like bedsheets. It’s rare that smallpox can infect someone through the air of an isolated area. Secondly, “Smallpox has been
