Abstract
Fevers, chills, loss of appetite, nausea, muscle pains and headaches; all of these symptoms just from a little bite by a female mosquito. Only affecting humans, other mammals, and even more species of mosquitoes. The disease is hard to point out from other flus, especially in the beginning stages. Some people get better within a week period. Some of those who improve in a day think it’s all over but then the fever returns as the pains do. Damage is caused to liver which can only mean the virus is getting worse. I choose this topic because it caught my attention and as I read about it I was intrigued more. I never knew about this virus so I thought about learning something new.

Yellow Fever In the article Yellow Fever introduction explains at one time Yellow fever was the scariest diseases. A wide spread of vaccinations successfully making the virus under control for about 40 years and more in the mid-20s. Although late 1980s it returned putting risk in the West and Central Africa (The Yellow fever initative: an introduction, 2015). Yellow fever is transmitted from a bite of a mosquito in jungles and tropical rainforests. Another word for the Yellow fever is Yellow Jack or Black Vomit. The yellow that in the name is from jaundice which affects most patients. This disease is the first disease that which an insect is who vector carried this infectious disease. The virus replicated near the site at which where it has injected into the body. In the article Philip S. Hench Walter Reed Yellow Fever Collection states when outbreak of this virus started in New Orleans in the early 1900’s the death toll was much lower than the past. From a Cuba doctor named Carlos Finlay told about the mosquitos transmitting the yellow fever virus. Even though he had proof of his finding and experiments his wonder work was oddly ignored until Walter Reed picked up on Carlos work when he was put in charge in the military (Carlos Juan Finlay, 1998-2001). In order to understand the virus when need to look more into it. By learning about this history, symptoms, treatments, causes, and preventions.
History about this diseases makes how causes and spread of infection and treatment more understandable. Recorded in the Yucatan holds the first presumed case of the Yellow Fever Disease in 1648. Displaying the symptoms and explaining how the spread from the disease are similar to later outbreaks. In 1702 New York City has a tragic loss of ten percent of its population due to the yellow fever. 1867 yellow fever returns to New Orleans causing 3,000 lives to be lost. 7,000 people die in 1885-1889 because of the disease. Finally in 1936 a vaccine for the yellow fever was made from researchers one of those who are Max Theiler, at the Rockefeller Foundation Yellow Fever Laboratory in New York City. Where it was first analysis and tested, production increasing as being seen as a threat of world war. The vaccine increases percentages of Hepatitis Diseases, causing him to make a safer vaccine in 1942. In March, a man from Texas returns from his fishing trip in Brazil and dies from the yellow fever accord in 2002. Causing him to be the third victim from the virus in the U.S since 1996. No one from the U.S has died in seven decades from the disease (The Great Fever, 2006).
Causes for the yellow fever are just from the simplest thing in the world form something you would never have thought could possibly cause so much trouble. In the article Yellow Fever Fact Sheet states yellow fever is an acute viral hemorrhagic disease only transmitted by infected mosquitoes. The word “Yellow” in the name of the virus is referring to a jaundice which affects some patients. This infection can cause really bad illness and mostly likely death. Out of all the people affected without any treatment will die which is about 50 percent. 30,000 out of 200,000 people died from the yellow fever, worldwide every year (Yellow fever fact sheet, 2010). The yellow fever is like the RNA virus belonging to genus Flavivrus. The causes from this virus spreads from one host to another mostly from monkeys to humans and usually person to person but only both species get this flu from a mosquito. The mosquitos either breed around homes, jungles, or in both. There are three types of transmission cycles for the yellow fever disease. There is the sylvatic yellow fever; consisting in the tropical rainforests occurring with monkeys that get the virus from an infected mosquito. Then there is the Intermediate yellow fever; which consists in semi-humid and humid parts in Africa. The spread cause from mosquitos and monkeys now increasing the contact from both species. Lastly, there is urban yellow fever which large epidemics then occur only when infected people into a highly number populated areas. With those who are affected and Ades mosquitos. The Urban yellow fever transfers the virus from person to person. The symptoms caused by this awful virus are very painful and makes people’s lives miserable. On the Health line website it describes the symptoms in 3 different stages. This stages are:
Stage 1: Called “acute” stage, the first phase lasts about three to four days. With headaches and fevers the victims may be flushed, loss of appetite, shivers and abnormal backaches.
Stage 2: Called “remission” stage, during this period symptoms go away. As they feel better many people begin to recover fully at this stage although other will being getting worse within 24 hours.
Stage 3: Called “toxic” phase, the most serious phase. Returning symptoms and some new ones begin to appear. Which are decrease urination, abdominal pain, and vomiting which may include blood. Some symptoms are occurred in the heart rhythm problem, liver failure; causing yellowing of the skin and eyes, kidney failure, seizures, delirium, and possibly bleed from the nose, mouth and eyes. This is the most fatal stage of this deadly disease (Yellow Fever, 2012).
Treatments and preventions are very helpful but this disease is has no cure for the viral infection itself. Although medical treatments of the yellow fever are mostly focused on calming down the symptoms as in muscle pain, fever, and dehydration. The risk of internal bleeding avoiding aspirin and any other anti-flammatory narcotics. Since there is no cure for this disease the prevention is very critical. Yellow fever vaccine is preferred for adults and children over the age of 9 months who plan on traveling or living in any countries that’s in any risk with yellow fever disease. Some travel clinics and local health care departments offer vaccines. Just getting the vaccine can help prevent the disease up to 10 years so make sure to schedule checkups every 10 years. If experiencing any of these symptoms or fevers be sure to get a hold of a doctor right away. If not you are in the fatal chances of death without any type of treatment or care from a physician. Although the vaccine is to help for some people the vaccine can hurt them more than help. People are recommend to talk to the care doctors first if having a low immune system such as HIV, cancer or thymus gland problems, any treatment that possible of disrupting immune system like steroid or treatments of cancer, having life-threatening allergic reactions to eggs, chicken, gelatin, or past vaccine for yellow fever. Or pregnant or breast feeding, even 65 or older, and any 9 months and younger children (Yellow Fever Causes And Treatment, 2013).
The yellow fever is a viral disease that can be quite deadly; without proper treatment it can lead to death. The virus slowly kills you within a week and it starts out with fevers, and muscle pains. Going to liver failure and kidney failure turning the skin yellow like jaundice. This disease is mostly prevalent in South America and Africa so if anyone plans on traveling to any of those places in the world need to go get a vaccine immediately. Going on vaccination is the mostly commonly way to get the yellow fever disease.
