Recommended: The effects of the ebola virus
In August 1967, a mystery virus infected workers from labs in Marburg and Frankfurt, Germany. Four weeks later, workers from a lab in Belgrade, Serbia, appeared to have the same illness. Twenty five lab workers from the three labs became sick. From the original infected, the virus spread to their medical personnel and a family member that were taking care of them. By the end of the outbreak, thirty one people were infected, and seven people died. The virus was identified to be the Marburg virus, named after the town in Germany with the most infected. (CDC 2014). Prior to the identification of the virus in 1967, very little is known about the history of the virus. It is possible that the disease had existed previously, but no information exists about the virus prior to 1967. The virus was identified by virologists in Marburg and Hamburg, Germany, three months after the initial outbreak. …show more content…
Because of the few differences that the two viruses share, there is no differences in how they are handled by medical personnel. Doctors and nurses that treat or may come into contact with the patient wear protective clothing and follow disinfection procedures which have been found to lower the possibility of infection. Patients with a filovirus are isolated from other patients and the public who may be susceptible to becoming infected. There are currently no vaccines or antiviral treatments for either Ebola or the Marburg virus. Supportive care is required as the patients typically require intravenous fluids or oral rehydration. Depending on the specific outbreak of the virus, the fatality rate may range from twenty five percent to more than eighty percent. The averaged fatality rate of the Marburg virus is eighty two percent, compared to the fifty percent fatality rate of the Ebola virus (that british
[1, 4, 5, 9, 13] There have been no documented cases where a human has contracted the disease from another human. [4] It appears, based on field and lab data, that infection requires direct contact with the virus through means such as contact with infective bodily secretions, urine, or tissues. [12] It is unknown to scientists how the virus can be maintained in the bat populations and avoids extinction as the host species becomes immune to its presence. [14] The incubation period from time of infection to the onset of symptoms is about 5-14 days in experimentally induced animals [4] and 8-14 days in natural field cases.
This virus is similar to Ebola, because it started in the same place. Lab workers in Germany, in 1967, contracted the new virus while working with African Green Monkeys, which had the virus. The virus is described as a hemorrhagic fever. It has a fatality rate up to 90% and spreads through human to human contact. The first symptoms can be as simple as a fever and a headache, then can progress to organ failure, and fatal internal bleeding.
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 medical field is a vast land of beauty but with great beauty comes immense horror. There are many deadly viruses and diseases found in the medical field. In the novel, The Hot Zone by Richard Preston, the author discusses the many deadly viruses found in the field. The viruses are widespread due to the errors that occur when the viruses are in the presence of human beings. The effects of the errors performed by the human race include a decrease in population and wildlife. The viruses are spread in many different ways in the novel, but all are due to human mistakes.
Almost no one on Earth has any immunity at all to this virus, which makes ordinary vaccines useless against it. The sudden spread of the virus into Europe foreshadows an epidemic development that could be worldwide. Ultimately, there is no way to protect ourselves against epidemics. They will keep disappearing and coming back in new forms.
Discovery of this virus divided scientist in two groups; the ones in favor of publication the virus and the ones are against the publication. According to Fouchier in the article “The Deadliest Virus” by Micheal Green, he says that if more people have access to it, it

The Government and Politicians didn’t really care. Most of them ignore it and waited for the last minute. Others, like the President Ronald Regan spent more money on war supplies and other stuff, than helping the CDC find a cure. They were only given a certain limited space, no money, and outdated equipment.
Samples of tissue from patients infected with the mysterious disease were sent to the CDC Special Pathogens Branch for analysis. After a few weeks and several tests, the virologists linked the disease with an unknown type of hantavirus. Because other hantaviruses were known to be transmitted to people by inhalation or ingestion of rodent feces or urine, our next task was to collect as many species of rodent in the area as possible in order to pinpoint the source of the virus (AMNH). While trapping rodents, we decided that it was worth the risk to not wear protective clothing or masks so as to avoid alarming residents of "The Four Corners" region (CDC). After testing approximately 1,700 rodents we had found a link--the prevalent deer mouse carried the unknown type of hantavirus. But why was this mouse suddenly infecting people in this region? I was becoming frustrated, my years of work in medicine were failing me and I couldn't figure out why these people kept getting sick.

Traditionally, the most widely accepted theory was that the venereal form of the disease arrived on the shores of Europe along with Christopher Columbus's crew, when they returned in 1493 from a journey to the New World (PBS,Secret of the dead). Indeed, although no cases of the disease seem to have existed in Europe before Columbus sailed to the New World, it had reached epidemic levels on the continent by around 1500. Even moreso Syphilis, overtime was undesrtood to be a sexualy transmitted disea...
The Ebola virus was discovered in 1976. It has four strains, each from a different geographic area, but all give their victims the same painful, often lethal symptoms.
The symptoms were blisters of the skins with puss and bleeding with high fever. The government was very aware and thought they had a vaccine but the micro-organism morphed into another pathogen that was airborn and the previous vaccine was no
Marburg Virus is an acute and fatal strand of Filoviridae, there should be a heightened awareness of this virus since it is the predecessor of Ebola and devastated the world first with hemorrhaging. There is no cure and it’s believed to be transferred from primate to human contact. While there has only been one case in the United States of America, this virus devastated Europe and Africa over the years.
This disease was first diagnosed in 1918 and it was referred to as the “Spanish Flu” or “La Grippe.” To this day it is thought to of been the same strain as the swine influenza however it is still unclear. For this particular outbreak it’s not exactly know whether humans contracted the virus from pigs or vice versa. Either way between 20-40 million people died from it. The first confirmed case of H1N1 in the U.S. was diagnosed on April 15th, 2009. The CDC quickly began developing a vaccine due to the fact that it was declared a public health emergency about a week later by the government. It tu...
