The Yellow Fever Virus

Ava Schwartz Yellow fever compare and contrast In 1793 Philadelphia suffered from a deadly disease that spread all through the town; it was called yellow fever. The Philadelphia Doctors and the French doctors were attempting to treat yellow fever. The doctors had many ways to try to fix this, but they did not have the technology we do today. Yellow fever occurred 1793. The outbreak happened in Philadelphia. This sad event that killed many people was all because of infected mosquitoes. They came over with the ill refuges. About 2,000 to 5,000 people died. All in all, this was one of the one of the worst things to occur in history

Jamie Lucas Jeff Foster Microbiology March 9, 2017 SMALLPOX Smallpox is caused by the variola virus an extremely contagious disease. That can be spread through any type of contact with the virus. The virus is a member of the genus Orthopoxvirus, in the Poxviridae family. Smallpox has been considered eradicated in the United States since 1972. Virologists have speculated that it evolved from an African rodent poxvirus 10 millennia ago. The name is derived from the Latin word for "spotted" and refers to the raised bumps on the face and body of the patient. (Medscape.com) Smallpox has been to blame for the extinction and almost extinction of many cultures. The disease has been used as biological warfare since the beginning or war. At times,

The Disease Yellow Fever Throughout history many different diseases have infected the world. Such diseases consist of measles, mumps, malaria, typhus and yellow fever. Many of these diseases are caused by different things and originated in different countries. Yellow fever is a deadly disease caused by a viral

Throughout the 18th and 19th centuries, as the country grew and trade flourished, periodic epidemics struck regions of the nation as population density increased. Outbreaks of influenza, cholera took over the nation, and in the south, one of the most prevalent was yellow fever. Due to these diseases, a lot of public health policies were either created or changed to better suit the new issues arising. In this essay, I will argue that the Yellow Fever Epidemic of 1878 brought upon many changes in the health realm in terms of public sanitation. In order to prove the epidemic s place in the history of health policies, I will be discussing the creation of the new sewer system, waste disposal techniques, and other projects created.

While reading An American Plague, I noticed an interesting detail that Yellow Fever could actually be prevented. Murphy (2003) notes that doctors noted the symptoms of the sick patients from the disease Yellow Fever. Some of the symptoms were pain in the back and painful aching in the

The reason why it was called the Yellow Fever was because your eyes would turn yellow, thus showing that you had the disease. Not only that, you’d have liver failure and your

France was at war with many countries. John Adams later would write 10,000 citizens marched in Philadelphia, threatening to drag Washington and make him declare war. Adams thought that the yellow fever prevented chaos. At the start, people believed that the two-thousand five-hundred city’s African-Americans were immune to the fever. Philadelphians initially blamed the outbreak on refugees from France. People believe the disease spread person to person. Recommendation for ridding of the disease were smoking tobacco, cleaning yourself with vinegar, carrying a tarred rope, covering the floors of rooms with a two-inch-deep layer of dirt, chewing garlic, hanging a bag of camphor around your neck, lighting bonfires, and setting off guns in the

224 years ago, in 1793, a yellow fever epidemic roared over Philadelphia. This was a devastating time for all Philadelphians. Although there were no cures, there were treatments. There were two types of doctors back in this time; the French doctors and the American. Mosquitos are the cause of this. They (the mosquitos) got infected by the refuges. The mosquitos spread the yellow fever to mankind. This epidemic killed a couple thousand people.

Yellow fever is a virus that is usually found in South America and sub-Saharan Africa, where the virus is spread via mosquitoes. Symptoms of yellow fever often are not noticeable until four to six days after infection and vary in severity. The two phases of yellow fever include the acute phase and the toxic phase. In the acute phase, infected persons will experience mild symptoms such as fever and muscle pain. The acute phase lasts three to six days before evolving into the toxic phase. Symptoms of the toxic phase include high fever, bleeding from body orifices, jaundice, vomiting, and abdominal pain, and, eventually, the toxic phase becomes deadly, leading to low blood pressure, organ failure, shock, coma, or even death.

Yellow fever, a viral hemorrhagic fever, was one of the deadliest diseases to hit North America. It is transmitted by female mosquitoes of the Aedes aegypti species. When a person is infected with the disease, the symptoms of high fever, nausea, vomiting, yellowing of the skin (also known as jaundice) and muscle aches occur. The cause of Yellow Fever was not known to colonial doctors. It would not be known until 1900. Until then, eighteenth century doctors used the only knowledge they had to fight the

Yellow Fever, a disease that can’t be cured as of this century. In 1793, Yellow Fever had come to Philadelphia and killed thousands of people. There were some that have lived thru the epidemic which were the lucky but those who were not all died from Yellow Fever. One of the people that survived the epidemic was a teenaged girl name Mattie Cook. She survived the Yellow Fever disease and had to undergo many challenges thru this epidemic.

Yellow fever was carried by mosquitos that had bitten people containing yellow fever. The symptoms of yellow fever consisted of Mild cases cause fever, headache, nausea, and vomiting. Serious cases may cause fatal heart, liver, and kidney conditions (Mayo clinic).

Yellow Fever is a dangerous viral infection. Yellow fever gets its name from the fact that the disease typically causes the skin to become yellow as well as producing a fever. Brian R. Shmaefsky, author of the book Yellow Fever explains that "Yellow fever is also known by other names. Throughout history yellow fever was called black vomit, vomito negro, sylvatic fever, and Yellow Jack. Black vomit, or vomito negro, is known as very dark vomit that many infected people produce. Sylvatic fever gets his name from the fact that the disease is common in areas with jungles or forests. The name Yellow Jack was given by the newspapers because yellow fever was perceived to be as destructive as any enemy troop". In cartoons the disease was pictured as a skeleton wearing a yellow military jacket. The Virus is transmitted by mosquitoes in tropical regions, so it cannot be spread person to person by direct contact. The disease is principally spread in tropical regions of Africa and America. Every year it is recorded 200,000 cases of Yellow Fever, and 30,000 of that die. However, because of the poor record-keeping, the data recorded do not reflect the reality. Moreover, in the last years, epidemics are increasing the number of people affected by Yellow Fever. Even though there are ways to prevent it, it is dangerous because it can cause death and also it has many symptoms.

Mosquitoes pass malaria to humans through their salivary glands. Once the parasites have entered the blood stream, they go to the liver. In the liver they mature and undergo reproduction, forming merozoites. These merozoites enter the blood stream and inject themselves into red blood cells. Once inside the blood cells, they reproduce rapidly and within forty-eight to seventy-two hours, the blood cell bursts, releasing hemoglobin into the blood stream. It is the destruction of these blood cells and the hemoglobin released into the blood stream that actually causes most of the symptoms.

Of the many diseases spread by insects, none are actually caused by the insects themselves but by other organisms passed on when they feed or bite. Insects are capable of spreading diseases caused by many different types of microorganisms including bacteria, viruses, protozoan and others. Mosquitoes have earned the
