Because many Europeans had once had smallpox or were at least around it, they developed immunity. This immunity helped Europeans to be uninfected when smallpox epidemics occurred in the New World.In the Old World, the most common form of smallpox killed perhaps 30 percent of its victims while blinding and disfiguring many others. But the effects were even worse in the Americans, which had no exposure to the virus prior to the arrival of Spanish and Portuguese conquistadors. Tearing through the Incas before Francisco Pizarro even got there, it made the empire unstable and ripe for conquest. It also devastated the Aztecs, killing, among others, the second-to-last of their rulers.
Some of the effects included the different political and social changes which changed Europe. First of all, the Bubonic Plague brought many political changes to Western Europe that collapsed the Middle Ages and medieval society. Because of the fact that the plague was spreading because of the people coming in from the east, Europeans didn't want them to keep bringing in the plague. This lead to the decrease and disruption of trade, which meant prices went up because there weren't any goods coming in. Next, another change that the Bubonic Plague brought to the west was the fact that serfs were leaving the manors they worked on to see if they could find a better lifestyle and wages.
I. There are numerous amounts of diseases all over the world. In present time, these diseases are cured or contained by vaccines. A couple centuries ago, doctor Edward Jenner developed the first vaccine in 1796. He discovered this vaccine by observing his ambience.
Smallpox outbreaks have occurred from time to time for thousands of years, but the disease is now eradicated after a successful worldwide vaccination program. The last naturally occurring case in the world was in Somalia in 1977. After the disease was eliminated from the world, routine vaccination against smallpox among the general public was stopped because it was no longer necessary for prevention. In 1970, when smallpox was nearly eradicated, a previously unrecognized orthopoxvirus named monkey pox was identified in humans. The first known human case occurred in the Equateur province of Zaire (now known as the Democratic Republic of Congo (DRC) when a 9-year-old boy developed smallpox like illness, which was eventually confirmed as human monkey pox by the World Health Organization (Ladnyj et al., 1972).
During a visit to Mexico, Dobyns read Jesuit records of births and deaths and there was much more death. Diseases, such as smallpox, decimated Indian population and allowing Europeans to easily conquer the natives. Since so many people died, Dobyns calculated that the population of the west was actually 112 million in 1491, more than Europe at the time. He estimated that after 130 years after contact with Europeans, the Native American population decreased by 95 percent. Some criticized Dobyns’s publishing's as politically driven.
Diseases such as diphtheria, the bubonic plague, influenza, typhus, and scarlet fever were scattered throughout the New World as the Europeans settled inland. The Native Americans who had little to no resistance against these diseases succumbed. It is estimated around 90% of Native Americans population perished due to the diseases listed above. However the explorers weren’t the sole transmitters these diseases. Critters and livestock like mosquitoes, black rats and chickens that migrated along with the Europeans also carried the bacteria.
Prior to the discovery of the New World by Europeans, Native Americans populated what is presently North and South America in massive numbers; however, due to massive population loss, mainly caused by diseases introduced by Europeans and Africans, the Native Americans were unfortunately forced to live as inferiors to the Europeans. A major issue that faced native populations of the New World was the fact that the Europeans introduced foreign animals that carried diseases the natives had never seen before. Specifically in Mexico and Peru, the natives had alpacas and llamas in small and isolated groups, so diseases were not able to originate in them [McNeil 178]. On the other hand, the animals that the Europeans brought over, such as cattle,
Native populations rapidly decreased after 1492 because of disease, enslavement, and war. When the Europeans traveled to the New World they brought diseases with them that caused many deaths. Also the Europeans wanted slaves to work for them so they didn’t have to do anything by themselves. War began to break out because of the many deaths happening. The most important cause of the decline was disease because it caused the most deaths and also one people were noticing the diseases they would move around trying to avoid it, but only to make it worse by infecting more people.
The Europeans, unintentionally, started an epidemic that would spread throughout the Americas and single handedly kill millions of Natives. Europeans brought diseases such as cholera, malaria, measles, mumps, smallpox, typhoid, and yellow fever to name a few. The only known disease that the Natives probably had was syphilis. Although the Europeans inadvertently shared their diseases they did share other
Now that pharmacists have progressed in the study of medicine we now have vaccines to limit the spread of Chickenpox. It wasn’t mandatory to take it until the 90s, so many kids born in the 2000s have and may never have Chickenpox. Chickenpox was like any other disease in the 1800’s- when people started to become aware of the unsanitary conditions, and change their lifestyle-it slowly started to vanish. “People develop antibodies, and the diseases eventually die out, scarlet fever is an example (Health Facts 1).” Similar to Scarlet Fever, Chickenpox ultimately died out, and now has almost
