Europe has a long and complex history of disease outbreaks and epidemics. Some of the most significant and well-known European diseases include the Black Death, influenza, and cholera. These diseases have had a profound impact on the continent and its people, shaping the course of history and shaping the way that we understand and approach public health today.
The Black Death, also known as the bubonic plague, is perhaps the most infamous of all European diseases. It is believed to have originated in Asia and spread to Europe through the Silk Road, arriving in the early 1340s. The disease was highly contagious and spread rapidly through the continent, killing millions of people in a matter of years. The plague was especially devastating in cities, where crowded and unsanitary conditions facilitated the spread of the disease. The Black Death had a profound impact on Europe, killing between 30% and 50% of the population and altering the social and economic landscape of the continent.
Influenza, or the flu, is another disease that has had a significant impact on Europe. This highly contagious respiratory illness is caused by a virus and spreads easily through the air. Flu outbreaks occur regularly and can be severe, especially in crowded and confined spaces such as schools and offices. The flu can also be deadly, particularly for vulnerable populations such as the elderly and those with underlying health conditions.
Cholera is a bacterial disease that is spread through contaminated water and food. It causes severe diarrhea and dehydration, and can be deadly if left untreated. Cholera outbreaks have occurred throughout European history, often in the wake of wars and other disasters that have disrupted sanitation systems. The disease is still a threat in some parts of Europe today, particularly in areas with poor access to clean water and sanitation.
In conclusion, European diseases have had a significant impact on the continent and its people. The Black Death, influenza, and cholera are just a few examples of the many diseases that have shaped European history and continue to pose a threat to public health today. Efforts to prevent and control these diseases, such as vaccination and improved sanitation, have played a crucial role in protecting the health of Europeans and ensuring that future outbreaks are less severe and less widespread.
Study shows surge of bad disease genes in Europeans
If the people would have continued with what they had started, they would not have been conquered for before August 21, 1521, the Spaniards were almost defeated. Archeological evidence suggests that there were several periods of significant spurts of population growth and sudden declines in the Americas long before European contact. The most deadly were smallpox, malaria, viral influenza, yellow fever, measles, typhus, bubonic plague, typhoid fever, cholera, and pertussis whooping cough. Comparing the two sets of genes, the team discovered several immune-related gene variants that were rare among the living. Through the Columbian exchange the Europeans brought multiple new diseases to the Native American population, including small pox.
European diseases left a genetic mark on Native Americans
So, why did the native peoples not have diseases that could be communicated to the Europeans? How many natives were killed by European diseases? The Native Americans had zero resistance to the new diseases since they had never been exposed to them before. Conrad includes irony, imagery, and symbolism to criticize white imperialism and argue that Europeans cause destruction and native societies. Unfortunately for seventeenth-century Native America, the cities and towns of Western Europe produced the bulk of North American colonists. He also states how germs travel through animals and bugs and how the germs can destroy white blood cells at a rather rapid pace. There is no question that these diseases were devastating, but their impact has been exaggerated. The Europeans were said to be thoroughly diseased by the time Columbus set sail on his first voyage Cowley, 1991.
Today, we know that viruses can travel long distances either on people or on their trade goods. Today the vectors, or carriers, of many of these diseases, have already been detected on the European continent — and with climate change this trend is expected to continue. Further investigations in Croatia found that nine healthy inhabitants had IgG antibodies against dengue, indicating a past infection with the virus; further research revealed that even more individuals had been exposed. The Natives also had their common diseases such as polio, hepatitis, encephalitis, and syphilis. Sickness , No Resistance.
With a temperature increase of 2-4°C, diseases like dengue, Chikungunya and others could well become a reality in Central and Northern Europe. It can also help explain why different people have so many different reactions to the same drug, said Joshua Akey of the University of Washington in Seattle who led the study. Epidemics, perhaps smallpox or influenza, swept through the region and claimed many lives. With Europeans came all of the common diseases they had already dealt with in the past such as smallpox, measles, malaria, yellow fever, influenza, and chicken pox. It was the devastation brought by deadly diseases infecting an unsuspecting population that had no immunity to such diseases.
These factors in themselves had a more detrimental impact on some Native groups, and for the indigenous population as a whole, these factors worked in a deadly cabal with germs to cause epidemics, exacerbate mortality, and curtail population recovery. The natives were not the only ones affected by the dead, however, for the The Role of Disease in European Exploration and Colonization The Role of Disease in European Exploration and Colonization Human mobility, in terms of European transcontinental exploration and colonization, began to truly flourish after the 1400s. How did diseases affect the Native American population? Genetic counselors review the results of your test and invite you to take part in a genetic counseling session. Swedlund; The University of Arizona Press, ISBN-9780816500246 This book does not specifically address what happened in the Chesapeake region to the Powhatan Indians, but I have to think that findings in this book must apply to some degree to the Jamestown story as well. Moreover, within the next fifty years, the population of natives which began at an estimated one million would drastically decrease to merely five hundred men, women, and children said one Spanish observer. The study finds that in the past 5,000 years, European-Americans have developed a huge batch of potentially harmful genetic mutations — many more than African-Americans. These alien maladies seem to haunt all classes of our society and are especially deadly for our children.
But, by far, the greatest killer was small pox. In the 20th Century, researchers Borah, Cook, Dobyns, McNeill, Crosby expanded on the lack of immunity factor among virgin populations to account for the massive die-off of Natives. Is there nothing we can do? Health and the Rise of Civilization. The worst being the syphilis, this disease was spread through sexual contact and managed to make its way back to Europe and became an epidemic… Essay On Native American Disease When so many humans live together in relatively close quarters, particularly with lack of good, or any, sewage systems, disease spreads quickly with the general population continually getting exposed to numerous bacterium. But climate change means that several such health threats may already be on our doorstep. Mayan civilization had already experienced a long period of decline by the time it encountered European explorers and invaders, but the Inca Empire was at its peak when the Spaniards conquered it in 1532. That question will never be answered.
Basically any European who crossed the Atlantic during the 16th century had battled illnesses, such as smallpox and measles, during childhood and emerged fully immune. They then sequenced DNA samples from 25 Tsimshian living near Prince Rupert today. Mass epidemics were virtually unknown in the New World prior to the invasion of the Europeans. Disease and Social Diversity: The European Impact on the Health of Non-Europeans. In recent years, the impact on health has been underestimated — but the evidence is mounting that it could be more devastating and progress faster than initially thought, especially if we fail to respond in time. This page will likely take me a while to complete, as I'll have to find and acquire source material for reliable information. Also, for comparison, John Rolfe 37 years; John Smith 51 years, Thomas Rolfe 65 years Comparison to Mayan and Inca culture mortality "Pre-Columbian Virginia was not a disease-free environment, but the people's living conditions were far healthier than those in English cities, so that epidemics of alien diseases could not wreak nearly the same havoc that they did in urban Mexico and Peru, which endured an estimated 90 percent mortality.
The diseases proved to be so deadly and contagious because the Indians had no immunity to them being exposed to the foreign germs for the first. By far, the native peoples of the Americas lived in a much cleaner and healthier environment. What can you do? Most were mutations that are known to weaken proteins, Akey said, and most of these harmful mutations were also in the people of European descent. Between 1492 and 1650 the Native American population may have declined by as much as 90% as the result of virgin-soil epidemics outbreaks among populations that have not previously encountered the disease , compound epidemics, crop failures and food shortages. They had a good diet and were very active. Numbers from Nowhere: The American Indian Contact Population Debate. The catastrophic epidemics that accompanied the European conquest of the New World decimated the indigenous population of the Americas.
And 73 percent of these mutations only appeared in the human genome in the past 5,000 to 10,000 years. Kim TallBear, a native studies researcher at the University of Alberta in Edmonton, Canada, says the study is well designed and provides "deeper genetic resolution on what we already know. The purpose of the counseling session is to provide you with more information and resources to help ensure the best possible outcome for any children you might have. The hope is that more people will take advantage of genetic screening in order to be more informed of their chances of being affected by Gaucher and of available treatments. A substantial difference between the Spanish colonies in Mexico and Santa Fe was that: Mexico had more Spanish settlers because of gold.
Initial European reports about the New World speak of a veritable Eden, populated by healthy, long-lived people, who could cure illness with indigenous Smallpox, measles, Impact Although a precise determination of the population of the Americas in 1492 is probably impossible, there is no doubt that contact with Europeans resulted in a massive demographic collapse of the Native American population. Early seventeenth-century France, England, and the Netherlands were unhealthy places to live, especially in the towns and cities. One reason for this was a messenger bearing the news of the invasion to his people could carry the diseases as well as his message. One native population called the Tainos started with about 1 million people and dwindled down to about 200 in the span of about 50 years. Very lean women often have a harder time conceiving; if they are malnourished, they will have more difficulty carrying fetuses to term.
