Dengue Fever : Symptoms And Symptoms

It started in central Asia, 1338 awakened by a drought, slowly makings its way to Europe. It finally hit Europe in 1345, 8 years later from the awakening, it first affected Crimea when a trade was being done with the merchant's Italian sailors and Mongolian's but it got out of hand until the point where the Italians were held up in a castle with nowhere to run for a year. The Mongolians soldier finally backed off but when their men starting dropping dead they had the idea to throw the infected dead bodies over the castle wall and into the castle, it was the first bioweapon created. Some of the Italian sailors managed to get away but they ended up carrying the mysterious death with going from town to town but no one would let them stop as infected rats had hidden within the cargo. But it was too late, in 1347, Sicily, the sailors docked but they were forced to move on, the brief encounter, however, allowed the infected rats to climb ashore and start spreading the disease. Soon it spread throughout trade routes such as the silk trade route which

Not unlike many of today’s flu outbreaks, bubonic is thought to have also originated in China. As early as 1346, rumors surfaced in Europe of a terrible plague which had ravaged Central Asia, India, Asia Minor, the Middle East and

Individuals with mild symptoms of West Nile Virus make up about twenty percent of the populations of infected humans. This form of the disease is known as West Nile Fever. The symptoms of West Nile Fever include: fever, headache, tiredness, body aches, nausea, vomiting, swollen lymph glands, and a skin rash appearing on the back, chest or stomach. A headache and high fever are the most common indicators for a West Nile Virus infection. These mild symptoms can last anywhere from a few days to several weeks. (California Government, 2005).

The diseases often spread quickly ahead of the Europeans. One example is that of the Spaniards. When the small pox disease first entered America in 1518, it only affected those who where around the Spaniards. However, over time, the disease spread, crossing

Once anyone gets a bite from a mosquito the side effects and symptoms won´t start showing up until 3-15 days after the initial bite, that is only if the mosquito was infected. Some cases are a lot worse than others (Centers). The mild or less severe case would be a headache and a fever. The more severe case would be headache, fever, body ache, swollen lymph glands, and in the worst possible scenario, death. No one can help weather you get a really bad case of

As the disease progresses the pulse slows and weakens, bleeding of the gums, and bloody urine occur. In more severe, usually fatal cases, jaundice occurs, which is what the disease is named for. Jaundice is when the patient's skin turns yellow and is the final definitive test to detect yellow fever, although by that stage it is usually too late. In the rare cases where people recover from the disease, the person develops an immunity to the disease.

A small amount of patients recover from the disease and then get even worse symptoms of it. The high fever returns and the liver and kidneys are affected poorly. Bleeding can occur from the mouth, nose, stomach, or eyes. Vomiting can also occur and will be very painful. Those who enter the toxic state of the Yellow Fever disease die within 7-10 days.

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.

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.

The yellow fever is basically malaria, which is spread by thousands of female mosquitoes in Philadelphia from August to the beginning of December. The fever had come from the caribbean ships and from there, it spread

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).

The Yellow Fever virus came from Central or East Africa. With transmission between primates and humans, the virus has been spread from there to West Africa. The virus was probably brought to the Americas with the slave trade ships from 1492 after the first European exploration. The first case of Yellow fever was recorded in Mexico by Spanish colonists in 1648. Consequently, the virus started to spread also in North America. In Philadelphia in 1793, more than the 9% of the population die. The American government had to escape from the city that was the temporary capital. One of the most famous outbreaks happen in Europe in Barcelona in 1821.How explains the article "The 'plague' of Barcelona. Yellow Fever epidemic of 1821", the outbreak of

There are two different conditions of Yellow Fever, mild and severe. Mild cases’ symptoms include fever, headache, nausea, back pain, body aches, vomiting, and weakness in the arms, legs, and muscles. More severe cases’ symptoms consist of vomiting blood, bleeding from nose, mouth, and ears, slow heart rate, liver failure, kidney failure, seizures, and comas. A person with Yellow Fever can easily be diagnosed by doctors by the color of their skin. A person with Yellow Fever shows skin that is starting to turn yellow from

Although throughout history only about 2% of humans infected happened to be fatal, the other 98% suffered through a wide variation of symptoms that focused on different aspects of the body1. In humans, Rift Valley fever can have an incubation period of 2 to 6 days with some patients showing no signs and a majority of the others suffering from flu-like symptoms, such as vomiting, headaches, limb pains, and diarrhea2. These minor symptoms can last from 2 to 7 days before the patient’s adaptive immune response is implemented and begins its fight against the virus, followed by a complete, or nearly complete, recovery2,3. Though these symptoms seem like common ailments that exist everywhere today and are practically harmless in the long run, Rift Valley fever has the potential to turn them into a lifelong nuisance.

The symptoms of yellow fever are varied. The virus has an incubation period of three to six days. The first symptoms will be fever, muscle pain, backache, headache, shivers, and loss of appetite, nausea, and vomiting. Frequently a slow pulse accompanies the fever. Most people improve after three to four days, however in 15% of the cases; patients go into a toxic phase within 24 hours. Fever reappears, and they exhibit jaundice and abdominal pain with vomiting. Bleeding occurs from the mouth, eyes, nose and stomach. The kidneys fail to produce urine, and blood appears in the vomit and feces. Half of the patients who experience this toxic phase die in ten to fourteen days. Due to the fact that many of these symptoms are identical to malaria and other diseases native to the areas, yellow fever is difficult to recognize. Blood tests can identify the virus, but may not be easily available to people in poorer developing countries.
