The yellow fever is “...a tropical viral disease affecting the liver and kidneys, causing fever and jaundice”(CDC), and often times causing several thousand fatalities per year on average. This illness is frequently found in South America and is transmitted by mosquitoes. Specifically the “Aedes aegypti mosquito”(CDC). Most commonly found in South America due to it’s uncommonly high-temperature range, extreme humidity and lastly the vegetation & population. Out of all of these factors that advance to the tremendous upset of yellow fever, the ultimate factor that is responsible for yellow fevers devastating effects on the South American population is the climate, weather, and vegetation.
First of all, one aspect that leads to yellow

For example, the most common weather pattern in South America is an “average to mild weather pattern for the majority of the year”(out America-travel-experience). Which is a green light to go for the Aedes Aegypti mosquito because there isn’t extreme weather to have to worry about when laying larvae or living in general. Secondly, South America has “warm rain”, which according to the CDC, “When rain floods the Aedes aegypti mosquito eggs with water, the larvae hatch. Generally, larvae feed upon small aquatic organisms, algae and particles of plant and animal material in water-filled containers”(CDC.gov). Furthermore, “ Egg production sites are within or in near to households” (CDC.gov). This means that the mosquitoes typically migrate towards the rain for the sake of breeding purposes. In conclusion, the weather in South America is a big reason towards the growth of yellow …show more content…
First of all, according to rmgsc.cr.usgs.gov states “45% of South America is heavily covered with tropical rainforests and another 15% is covered by trees, bushes, etc.” this means that with the trees and plants that there is a lot of water as well as the sun for the heat and the moisture for the Aedes Agypti Mosquitoes to not only live but also thrive. Secondly, the population plays a big role in the spread of yellow fever. For example, in South America, there is 387.5 million people who live in South America, which means if one person got bit if the disease was contagious with the warm climate and a number of people the disease would spread like a wildfire. In addition “On average 200,000 people die every year worldwide”(history.com staff). Furthermore, “The majority of those infected will be asymptomatic or have mild disease with complete recovery.In the case of more severe symptoms people will become, symptomatic but recover, weakness and fatigue may last several months.Those who recover from yellow fever generally have lasting immunity against subsequent infection”(CDC). This means that the people who do get infected will mostly recover in good health and have an immunity to other viruses and diseases. In conclusion, the vegetation and the population is the last greatest reason to the spread of yellow
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 body. This detail led me to wonder if there was a way that you could prevent Yellow fever. Centers for Disease Control and Prevention says that wearing bug repellent will reduce the chances for getting bit by a mosquito and they also talk about having more clothing on your body will also help because then mosquito's can not bite you. The article also talks about vaccines because we know have a yellow fever vaccine and that will cure yellow fever.
Ecological factors that encourage the Anopheles mosquito, and thus also encourage the prevalence of malaria include: being near the equator, densely populated areas, warmer temperatures, standing water, maintaining water for irrigation and deforested areas. (Holy p.1)
Yellow Fever, an epidemic that broke out in 1793. The people treating this disease was the doctors from Philadelphia and France. And what was happening is that this yellow fever was being treated. Now you this all started in 1793 when yellow fever started breaking out worse than ever. Now where this is happening was in Philadelphia. This happened is because of those pesky infected mosquito. This happened because with the infected mosquito came infected refuges. The worst part is trying to figure out how many people died because no one really knows exactly how many people died. We know it’s somewhere between 2,000 and 5,000 and it’s so sad what happened and that back then we didn’t know enough about this to really help
Yellow fever came in like a wrecking ball, across Philadelphia, wiping out everyone in it’s path. American and French doctors' are finding out cures to save the infected victims. In Philadelphia of 1793, around 2,000-5,000 people were killed by yellow fever. The reasoning behind why they got yellow fever was because the infected mosquitos. The mosquitoes came in by foreign ships, because of the water at the bottom of the ships.
How many people died? 4,000+people died. This happened in Philadelphia during 1793. Who? The American and French doctors. Why? Foreign ships brought mosquitos. How? Infected mosquitos. What is it?… Yellow Fever.
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.
I have decided to discuss the article “Where's Zika Most Likely in the U.S.? The Answer May Surprise You” by Maggie Fox. There is a lot of concern in the news, throughout the healthcare industry, and the United States about Aedes aegypti mosquitoes and its’ role in the cause and symptoms of the Zika virus. Many factors play into an ideal climate for the mosquitoes. Heat, humidity, and heavy rains in the summertime will provide an ideal climate for them to thrive. According to the Center for Disease Control and Prevention (2016), “Zika virus spreads to people primarily through mosquito bites. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon” (Zika virus, para. 1). However, the fear that there will be a major Zika virus outbreak here in the United States is unsubstantiated at this time. The CDC (2016) notes, “Outbreaks of Zika have occurred in areas of Africa, Southeast Asia, the Pacific Islands, and the
Now, vaccinations are recommended for those who want to travel to some parts in South America and Africa (mayoclinic, 2014). Only a safe and very effective vaccine can prevent the Yellow Fever. Five of the most common preventions are being aware of peak mosquito hours (which is usually from dusk to dawn), wearing proper clothing (like long sleeved shirts and long pants), avoiding outside exercises when mosquitoes are active, being in air-conditioned or well screened houses and using an EPA registered repellent (CDC, 2014).
Summary: The yellow fever outbreak that took place in Africa this past year was a hidden disaster which exposed the flaws in the emergency vaccine supply. The epidemic essentially exposed a race between the mosquitos that spread yellow fever and the vaccines that protect people against yellow fever. Early in December 2015 in Africa, the first few deaths by yellow fever were misdiagnosed as merely food poisoning. As soon as the true culprit was exposed, emergency stockpiles of vaccines were exhausted before a small region was protected. However, the outbreak was mitigated due to the help of a colossal vaccine campaign that stretched the supplies by diluting vaccine doses all thanks to special donors such as Brazil and South Sudan. This outbreak barely got any coverage or attention due to the focus being on the Zika Virus epidemic. The yellow fever virus reached Asia via workers who worked in Africa; if the virus got a base in Asia, it would have been very traumatic. The virus was spreading to major
There has been a large outbreaks of yellow fever and everyone in a warm climate is at risk. There has been ample
Yellow fever is a deadly disease caused by a viral infection that is transmitted through the bite of an infected mosquito. Although it is found to be most common in males in their early 20's, yellow fever can affect any sex, race, or age. Since yellow fever is carried by mosquitoes, it is most often found in areas such as Central America, the northern half of South America, and Central Africa where mosquitoes are abundant. The reason why it is found so often in these
It tropical and sub-tropical climates temperature, humidity, and rainfall work together to create a breeding ground for mosquitoes. Mosquitoes are a host for communicable diseases one in particular is called malaria. Malaria is a parasitic disease that infects a particular type of mosquito, Anopheles mosquitoes, which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented (Global Health - Division of
For most of time Yellow Fever was an endemic specific to Africa, however, when world started to become more globalize the disease spread to America through infected mosquitos a broad ships. Because the mosquitos like the warm weather and lay their eggs in standing water, the souther climate of America was an ideal environment for them to thrive, during the summer months. One outbreak of Yellow Fever, in Memphis, had a great impact on the city. Although the Yellow Fever was prominent in the port cities rail roads carried it further inland. Yellow Fever was an awful disease that caused, miserable symptoms and the panic of the people.
This type of mosquito that usually carries the yellow fever is called Aedes aegypti. Among the two kinds, urban yellow fever is the cause of most yellow fever outbreaks.
