This infection is a standout amongst the most deadly and horrific infections known to development. Ebola hemorrhagic fever is serious, regularly deadly and it influences monkeys, gorillas and people. The Ebola infection is a part of a group of RNA infections known as filovirus (family Filoviridae). At the point when amplified by an electron magnifying instrument, these infections have the presence of long string-shape, with little snare or circle toward one side. There have been four recognized strains of Ebola. Three of the four types of Ebola infections recognized so far have created ailment in people. Ebola-Zaire was found in 1976 and was name after a stream in Zaire, Africa, where it was initially experienced. Ebola Sudan was found in Western …show more content…
The exact area or inception of Ebola infection is still at this point obscure. Since the common natural surroundings (supply) of the infection is undiscovered, the nature in which the infection first shows up in a human host has not been dead set. Be that as it may, specialists have hypothesized that the first patient gets to be contaminated through connection with a tainted creature. Gathering of creature examples is right now underway to focus this. The possible species in tropical Africa are diverse to the point that a long and blessed pursuit is prone to be …show more content…
Transmission of the infection has additionally happened as an issue of hypodermic syringe being reused in the treatment of patients. Reusing needles is not a rare practice in creating nations, for example, Zaire, Gabon, and Sudan, where the medicinal services framework is extensively under-financed. Patients who have recouped from a sickness brought about by Ebola infection may not posture genuine danger for plague contamination. All things considered, the infection exists longer in the procreative organs, so it might be available in the male testicles for a protracted time of time (up to seven weeks) and thus it is possible they can spread the infection by means of close
On November 28th, Dr. Peter Jahlring of the Institute was in his lab testing a. virus culture from the monkeys. Much to his horror, the blood tested positive. for the deadly Ebola Zaire virus. Ebola Zaire is the most lethal of all strains. of the Ebola.
This revealed to me that no one is exempt from stopping or catching a virus like Ebola.(226 Preston) I live in a society where we don’t have a virus affecting us like there is in Central Africa. This makes me more cautious of the things I would come into contact with such as sick people. It’s not as if that I would disown them if they were sick but I would take more measures to ensure that I wouldn’t catch their cold. Along with this I’ve been looking at the measures I take to ensure no one else would catch my cold or virus and that I can recover from it.
The Hot Zone is a true story about how the knowledge of the Ebola virus was first developed and the background behind it. The Ebola virus kills nine out of ten of its victims and it kills quickly and painfully. It is extremely contagious and the blood and vomit the victim lets out can spread the virus quickly. The Hot Zone goes into detail of the experience of getting to the bottom of the Ebola Virus.
In the Hot Zone: The Terrifying True Story of the Origins of the Ebola Virus by Richard Preston, published in 1995, is a novel about the origins and the development of viral hemorrhagic fevers, especially ebola and marburg. These diseases are all Biosafety Level 4 agents, which means that they are extremely dangerous because they are highly infectious, have a high case-fatality rate, and there are no known treatments or cures. Marburg Virus and Ebola virus are filoviruses belong to a virus family called Filoviridae and they can cause severe hemorrhagic fever in humans and nonhuman primates. Five species of Ebola Virus have been identified: Taï Forest, Sudan, Zaire, Reston and Bundibugyo. The book describes the history of these diseases by explaining
Ebola virus disease is the kind of thing that horror writers dream about, it brings the most frightening of infectious disease symptoms to mind. Just imagine victims bleeding from their eyes, ears and nose. The nonfiction book The Hot Zone by Richard Preston and the 1995 movie Outbreak, are excellent examples of our perception of the disease. Ebola is highly infectious, rapidly fatal, deadly disease with a death rate of up to 90%, after the onset of symptoms. It is transmitted through direct contact with an infected person or primates bodily fluids like blood, saliva, urine, sperm, etc. or by contact with contaminated surfaces or equipment, including linen soiled by the infected person's body fluids. The disease is caused by members of a family
The Ebola virus can be passed from one person into another by bodily contact. Airborne transmission of Ebola has not yet been confirmed, as there is no substantial evidence of this occurring. Researchers are still to this day observing the ways of transmission of this virus from one person to the next. In previous outbreaks, this infection has often occurred among hospital care workers or family members who were caring for an ill or dead person infected with the virus. Blood and body fluids contain large amounts of virus, thus transmission of the virus has also occurred as a result of hypodermic needles being reused in the treatment of patients. Under-financed health care facilities in countries such as Zaire, Gabon, and Sudan find reusing needles a common practice. This contributes the vast amount of fatalities of this virus in these cities.
Ebola can be spread in a number of ways. Ebola reproduction in infected cells takes about eight hours. Hundreds to thousands of new virus cells are then released during periods of a few hours to a few days. In most outbreaks, transmission from patient to patient within hospitals has been associated within the reuse of needles and syringes. High rates of transmission in outbreaks have occurred from patients to family members who provide nursing care without barriers to prevent exposure to blood, other body fluids such as, vomit, urine and feces. Risk for transmitting the infection appears to be highest during the later stages of illness. Those symptoms include vomiting, diarrhea, shock, and frequently hemorrhaging. Even a person who has recovered from the symptoms of the illness may have the virus present in the genital secretions for a short time after. This makes it possible for the virus to be spread by sexual activity. Complete recovery is reached only when none virus’s cells are left in any body fluids. This is quite rare.
The Ebola-Zaire branch was the first to be recognized and has the highest death rate of 89 percent. The Ebola-Sudan subtype has a death rate of 53 percent, and the Ebola Haemorrhagic Fever virus as a whole having a 68 percent death rate. Since the Ebola virus has not been recognized for a long time, it cannot be said for sure how it is transmitted though it is believed to be zoonotic, meaning that it is transmitted by animals and from contact with the virus, making it spread quickly through family and friends. It also transmits itself nosocomially, where it can transmit quickly through a health care environment, like a hospital. This is especially dangerous in places like Africa,...
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.
“The fruit bat may be Ebola’s ‘natural reservoir’- the creature in which the virus finds its primary home.” (p.15) The virus in bats evolve over time and cross over to another species. In this case, Ebola was crossed over into humans and the virus could become worse and worse as it evolves more. Therefore, the diversity of life is seen in the virus itself and the organisms who happen to obtain the
In 1976 the first two Ebola outbreaks were recorded. In Zaire and western Sudan five hundred and fifty people reported the horrible disease. Of the five hundred and fifty reported three hundred and forty innocent people died. Again in 1995 Ebola reportedly broke out in Zaire, this time infecting over two hundred and killing one hundred and sixty. (Bib4, Musilam, 1)
According to the World Health Organization, the reason why there are many Ebola outbreaks in West Africa is because they have “very weak health systems, lacking human and infrastructural resources, having only recently emerged from long periods of conflict and instability.” A hum...
According to the Centers for Disease Control and Prevention Ebola Symptoms are the following: severe headache, fever, muscle pain, fatigue, weakness, diarrhea, abdominal (stomach) pain, vomiting, and unexplained hemorrhage (bleeding or bruising). Symptoms may appear anywhere from 2 to 21 days after exposure to Ebola, but the average is 8 to 10 days (Centers for Disease Control and Prevention, 2015). The remains of a deceased individuals infected with Ebola continues to be contagious with Ebola for up to three days after the individual dies. Ebola lives on through bodily fluids such as: tears, saliva, urine, and blood (The Daily Beast Company LLC, 2014). Furthermore, when one dies the bodily contact continues as the body is washed and “wrapped in a shroud, mat or coffin and placed in the ground by several people, where more contamination is possible” (NewsHour Productions LLC, 2015). These sacred burial rituals have contributed to the spread of the disease named
Ebola is not transmitted by air, a person has to come in contact with it by means of bodily fluid (sweat or feces) in a living person or dead person and Centers for Disease Control and Prevention has even reported that Ebola stays in a man’s semen for up to 3 months after contraction. (Ebola (Ebola Virus Disease)-Transmission) iii. The recent outbreak in the Democratic Republic of the Congo has reported 62 cases and 35 deaths as of September 9, 2014 according to the Centers for Disease Control and Prevention and the reason for this large number is human to human contact. (Ebola (Ebola Virus
Recent studies have supported the theory that fruit bats may be the reservoir for the virus and may help replicate the virus (Nabel et al, 2007). Ebola is a highly contagious virus that’s part of a group called filoviruses- they are viruses that can induce a hemorrhagic fever in humans and primates. The virus is also heterogeneous in shape, which helps it evade standard imaging techniques, making it harder to study the virus in depth (Robinson, 2011). There are 5 different subcategories of ebolaviruses: Zaire, Sudan, Tai Forest, Reston, and Bundibugyo. Ebola Zaire is the one that’s associated with the recent outbreak in West Africa, with up to a whooping 90% fatality rate (Abelson et al, 2012). Reston is the only virus that has not caused disease in humans, only nonhuman
