Major, Walter Reed born September 13, 1851 was a United States Army physician who in 1901 led the team that proposed and confirmed the theory that yellow fever is imparted by a certain mosquito, instead of by direct contact by human. This gave impulsion to the new fields of epidemiology and biomedicine, and most promptly allowed the completion of work on the Panama Canal for solid ten years of 1904 until 1914 by the United States. Reed followed work started by Carlos Finlay and directed by George Miller Sternberg.
The evolutionary origins of yellow fever lied in Africa, with transmission of the disease from mosquitos to humans. Yellow fever originated in East or Central Africa and spread from there to West Africa. As it was extremely common in Africa, the natives had developed some immunity to it. When an outbreak of yellow fever would occur in an African village, most Europeans did not live for a extensive amount of time, the native population usually suffered nonlethal symptoms resembling the flu (influenza). Yellow Fever (A. aegypti), were probably transferred to North and South America from the importation of slaves from Africa, part of the Columbian Exchange following European exploration and colonization.The first outbreak of yellow fever in the New World was in 1647 on the island of Barbados. An outbreak was recorded by Spanish colonists in 1648 in Yucatan, Mexico, where the Mayan's called the illness xekik "blood vomit". Although yellow fever is most prevalent in tropical climates. Africa was not alone, North America had its fair share as well. The first outbreak in North America occurred in New York in 1668 as well as a outbreak afflicted Philadelphia in 1793. English colonists in Philadelphia and the French in the Mi...

...he first case of yellow fever among U.S. troops occurred. For the next several weeks, more innocent soldiers were incredibly sick by dysentery and malaria . Yellow fever soon spread rapidly, which mainly officers and doctors blamed on infected buildings in Siboney. But by July 1899, yellow fever returned to Cuba,but not as severe as the years before when the tragic disease became before our eyes.
Walter Reed discovered a preventative vaccine to prevent the occurrence of allowing oneself to get yellow fever, saving millions of people. During the Spanish American war in Havana, Cuba there was approximately one thousand six hundred deaths were from yellow fever within the three years of the war. As you have read, yellow fever took a huge toll on the world. Because of the vaccine (17D) founded by Walter Reed during 1937, the disease may still be persistent currently.

There is no definitive history or discovery date, but it is assumed that Yellow Fever originated in Africa and was brought to the Americas by Aedes aegypti mosquitoes “hitchhiking” on trade and slave ships. The first believed outbreak happened in 1648 in the Yucatán. It is “believed” because early documentation of disease and illness was not thoroughly investigated or described, they could have been caused by one thing or another. There is ...
The first discovery was made in 1952, in the developing field of virology. Virology is the study of viruses and how they behave. To develop the vaccines for the viruses, researchers infected the HeLa cells with many types of infections, such as measles, mumps, and the infamous poliomyelitis virus, also known as Polio. According to the Centers for Disease Control and Prevention (CDC), whose mission is to save lives and protect people’s health security, Polio is a "crippling and potentially deadly infectious disease caused by a virus that spreads from person to person invading the brain and spinal cord and causing paralysis" (Freeman). Jonas Salk, who was a virologist at the National Foundation for Infantile Paralysis (NFIP), used inactivated viruses (virus particles grown in culture and then killed by a form of heat) to create a polio vaccine. Salk drew blood from about two million children, which the NFIP checked for immunization.Through the collection of many HeLa cells and trial and error, the polio vaccine wa...
The yellow-fever started in Memphis, Tennessee in a restaurant and soon spread fast across the state and neighboring states. “Yellow fever, which is carried by mosquitos, originally came from West Africa and was brought to the United States on slaves ships” (History, 2009). The impact of the yellow-fever blamed and hated African Americans for spreading it in America. Some politicians that wanted to abolish slavery took this event as something positive for the black. The antislavery followers viewed yellow-fever as the slave owners fault since it was their slave ships that brought the infected to US soil. In the end, this influence both has a good and bad affect for the African American
The last time Typhus was recorded was by the British Troops during World War II. They had forty two cases of Typhus in 1942 and that was one year after the allied forces arrived. Then the year after that there was five hundred and eighty two cases of Typhus...
Hygiene was extremely poor prior to and during World War 1, especially for soldiers. Because of this and the fact that fighting soldiers couldn’t clean up wounds quickly enough, there were many deaths caused by infection alone. One big issue was trench foot. This was an awful infection caused by soldiers standing in the trenches for too long during battles. Over the course of the war, hygiene and infectious issues were being better dealt with. These issues led to vaccinations and treatment advancements. The earliest forms of the vaccinations and treatments used today were actually introduced in 1914. Those vaccinations and treatments have been improved upon since World War 1. One of the most fascinating things regarding medical procedures at this time has to be blood transfusions. It was 1917, when the first of hundreds of millions of blood transfusions was made. This idea has been improved upon as
With no treatment half of patients who enter the second phase die within ten to fourteen days. Similar to yellow fever, malaria was transmitted to humans through mosquito bites, causing symptoms such as fever, fatigue, and vomiting. Difficult to recognize at first malaria continues to cause yellowing of the skin, seizures, and even death; these symptoms normally begin after ten to fifteen days after being contracted. Malaria was brought over to early America through slavery and killed millions of people between the seventeenth and twentieth century. Throughout the growth and expansion of America there was been several disease outbreaks both endemic and epidemic such as small pox, measles, yellow fever, and malaria. Starting with the Colombian exchange and slavery these diseases were brought to the new world and spread like wildfires that devastated populations both native and nonnative. Most commonly known for the death toll on the native Americans these diseases were so costly due to low resistance, poor sanitation, and inadequate
Disease and war go hand and hand in war. Throughout history, any major military conflict opens a can of worms of disease and death, by moving people to new environments, as well as, cramming them into confined quarters the perfect habitat for human pathogens to prosper. At the turn of the last century Cuba was seeking independence from Spain, which the Spanish resisted by relocating rebel groups. This relocation and increase in density escalated the already problematic yellow fever epidemic. The fear of relocation caused many Cubans to immigrate to the United States, many with yellow fever in tow. While the United States joined the war effort for many reasons, including the prosperity of the sugar industry, the spread of freedom, or the sinking of the Maine, it was the pressing fear of disease that led to an imminent threat to the people of the Gulf Coast. This threat materialized after the US forces landed in Havana and experienced the disease firsthand. In response to the overwhelming number of infected soldiers, the US Government sent a group of Army physicians to undergo a major sanitation effort to clean up Cuba. The work of Walter Reed and the second Yellow Fever Commission through their sanitation efforts led to many advances in the understanding of disease and population health. Starting with the threat of escaping Cuban refugees to the treating of infected Soldiers to the advancement in epidemiology, yellow fever had a major impact on not only the US entrance to the war with Spain, but to the development of modern medicine and the first American Empire.
A few years before 1918, in the height of the First World War, a calamity occurred that stripped the globe of at least 50 million lives. (Taubenberger, 1918) This calamity was not the death toll of the war; albeit, some individuals may argue the globalization associated with the First World War perpetuated the persistence of this calamity. This calamity was referred to the Spanish Flu of 1918, but calling this devastating pestilence the “Spanish Flu” may be a historical inaccuracy, as research and historians suggest that the likelihood of this disease originating in Spain seams greatly improbable. Despite it’s misnomer, the Spanish Flu, or its virus name H1N1, still swept across the globe passing from human to human by exhaled drops of water that contained a deadly strand of RNA wrapped with a protein casing. Individuals who were unfortunate enough to come in contact with the contents of the protein casing generally developed severe respiratory inflammation, as the Immune system’s own response towards the infected lung cells would destroy much of the lungs, thus causing the lungs to flood with fluids. Due to this flooding, pneumonia was a common cause of death for those infected with Spanish Flu. Due its genetic similarity with Avian Flu, the Spanish Flu is thought to be descended from Avian Flu which is commonly known as “Bird Flu.” (Billings,1997) The Spanish Flu of 1918 has had a larger impact in terms of global significance than any other disease has had because it was the most deadly, easily transmitted across the entire globe, and occurred in an ideal time period for a disease to happen.

Throughout the ages, while the origins to this day continue to be debated, the strength and potency of the disease have rarely been in question. Syphilis, while not viewed as a huge threat due to a decreased number of cases in the mid-late 1990s, needs to be taken more seriously by the public because it is more dangerous than many realize, especially because it is extremely contagious, it is extremely elegant in the symptoms it produces, it has played a larger part in history than many would think, and there is a certain stigma which surrounds the disease, which in turn pushes individuals away from receiving the necessary testing.
The first recorded smallpox outbreak occurred in 1350 BC during the Egyptian-Hittite war. The illness was passed from Egyptian prisoners to the Hittite population affecting both soldiers and civilians. Although it wasn’t until the late 1600’s that people in Europe and Asia accidentally discovered that those infected with smallpox through a scratch on the skin, suffered from a less severe form of the disease than those who contracted it through the respiratory tract. In the early 1700’s doctors began to store samples of smallpox pus and scabs in jars. If an outbreak occurred the doctor would make a small cut in a person’s arm and smeared the pus into the wound. This process of intentionally infecting a person with the smallpox virus in order to make them immune to the disease in the future was called inoculation.
