What Are the Causes of Ebola? There is only one cause of Ebola. The cause of Ebola is an infection with the Ebola virus. There are no other causes of Ebola. Causes of Ebola: The Ebola Virus The Ebola virus got its name from a river in the Democratic Republic of the Congo (previously Zaire), in Africa, where the disease was first acknowledged. Ebola virus is one of two members of a family of RNA viruses known as Filoviridae. There are four identified subtypes of Ebola virus. Three of the four have caused disease in humans: Ebola-Zaire Ebola-Sudan Ebola-Ivory Coast. The fourth Ebola virus subtype, Ebola-Reston, it has caused disease in nonhuman primates (gorillas, chimps ect) but not in humans. The exact origin, locations, and natural habitat of Ebola virus remain unknown; however, on the basis of available evidence, and the nature of similar viruses, researchers believe that the Ebola virus lives in an animal host that is native to the African continent. They continue to search for the exact animal. Just as scientists are unsure of the animal host for the Ebola virus, they are also unsure how an outbreak of Ebola virus occurs. Researchers have hypothesized that the first patient becomes infected with Ebola virus through contact with an infected animal. Causes of Ebola: Transmission Once Ebola virus infects the first human, scientists do know how Ebola virus is spread from human to human. Transmission of Ebola occurs through direct contact with patients who have Ebola, or their body fluids (such as blood or secretions). The spread of Ebola most often occurs during the late stages of an Ebola infection. When someone becomes infected with Ebola, he or she will not feel sick immediately. For 2 to 21 days, the person feels normal; however, inside his or her body, the Ebola virus is multiplying. This period between…...

...According to the Ebola Response Roadmap (2014), their objective is to halt the spread of Ebola within 6 to 9 months; ultimately preventing the Ebola virus from being spread internationally. Due the rapid transmission rate of Ebola in Liberia, Guinea, and Sierra Leone, WHO launched an Ebola Virus Disease Outbreak Response Plan on July 31, 2014. It has been reported that over 3,000 people have been infected with the Ebola Virus and 1,400 people have died; many of them being volunteer healthcare workers. As a result of this, the national authorities in conjunction with WHO and other partners have increased control measures to keep the virus contained. Although there is a great effort being made to contain the Ebola virus, the record outbreak is still being transmitted at an alarming rate. The Ebola Response Roadmap outlines three major objectives: to attain nationwide coverage with corresponding Ebola response in the countries that have a vast transmission rate, to employ immediate response teams to areas with contained transmissions and/or with primary cases, and to promptly detect and respond to all Ebola cases in a timely manner (Ebola Response Roadmap, 2014). The Emergency Response Framework outlines three levels for responding to an outbreak. A Level 1 emergency is a single country or multiple countries with a minimal threat which requires a minimal scale response. A Level 2 emergency is single or multiple countries with a moderate threat which requires a moderately......

...New York revises controversial policy on Ebola quarantines amid pressure New York Gov. Andrew M. Cuomo (D) on Sunday revised a controversial policy to quarantine returning health-care workers from Ebola-stricken nations, under pressure from the Obama administration and medical experts over the aggressive measures. Elaborating on the procedures, Cuomo said health-care workers who have been in contact with Ebola patients but do not show symptoms of the deadly virus can return to their homes but will be forced to remain there while being monitored by state health officials for symptoms. He said those being monitored can interact with family and friends. “It’s not like this is the toughest duty,” Cuomo said in a news conference late Sunday with New York City Mayor Bill de Blasio (D). The change separates the state’s quarantine process from that of New Jersey, which has come under scrutiny after the weekend retention of a nurse who showed no symptoms of Ebola. Kaci Hickox, who returned from Sierra Leone after working with Doctors Without Borders, has been held in isolation at a site attached to a New Jersey hospital. On Sunday, Hickox told CNN’s Candy Crowley on “State of the Union”: “This is an extreme that is really unacceptable, and I feel like my basic human rights have been violated.” Cuomo said New York’s new policy is more in line with those of the Centers for Disease Control and Prevention. He said people who are quarantined in their homes will be able to interact......

Ebola Virus Disease

...Ebola virus disease Key facts * Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. * The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. * The average EVD case fatality rate is around 50%. Case fatality rates have varied from 25% to 90% in past outbreaks. * The first EVD outbreaks occurred in remote villages in Central Africa, near tropical rainforests, but the most recent outbreak in west Africa has involved major urban as well as rural areas. * Community engagement is key to successfully controlling outbreaks. Good outbreak control relies on applying a package of interventions, namely case management, surveillance and contact tracing, a good laboratory service, safe burials and social mobilisation. * Early supportive care with rehydration, symptomatic treatment improves survival. There is as yet no licensed treatment proven to neutralise the virus but a range of blood, immunological and drug therapies are under development. * There are currently no licensed Ebola vaccines but 2 potential candidates are undergoing evaluation. Background The Ebola virus causes an acute, serious illness which is often fatal if untreated. Ebola virus disease (EVD) first appeared in 1976 in 2 simultaneous outbreaks, one in Nzara, Sudan, and the other in Yambuku, Democratic Republic of Congo. The latter occurred in a village......

...EBOLA VIRUS (EBOV)1 Ebola Virus (EBOV) Alaina White Microbiology 11/04/2014 EBOLA VIRUS (EBOV)2 Ebola Virus (EBOV) The Ebola virus causes a serious illness, that causes haemorrhagic fever in humans and animals which, if it is not treated in time is often fatal. Diseases that are fatal like Ebola, affect the body's vascular system, which makes it hard for the blood to circulte through the body. According to the World Health Organization (WHO), the first notification of the ebola virus was mentioned in the Ebola River valley in Zaire for the time of an outburst in 1976 (Olival et al., 2013). Researchers claim that the virus is zoonotic (animal-borne), with 4 out of 5 subtypes that happen in animal hosts close to Africa (MacNeil et al., 2010). Literature Review It has been proven by scientists that the Ebola virus can be transferred from one human beng to another by means of bodily contact. The common geographic territory that ia mostly influenced by divergent subtypes of the Ebola virus is Central Africa, especially the cities of Zaire, Sudan, and Gabon (Chepurnov, Bakulina, Dadaeva, Ustinova, & Chepurnova, 2009). Ebola virus infection runs its course from 14 to 21 days. Firstly, the infection can be identified with symptoms that are uncommon for the flu, including malaise, fever, and muscles pain. With the progress of infection, patients experience acute bleeding and coagulation abnormalities such as a rash, gastrointestinal bleeding (Chepurnov, Bakulina,......

...Name: Professor: Title: Date of Submission: Origin and Spread Ebola Background According to WHO, Ebola which is a serious, acute illness if untreated is very fatal (WHO.Int). Ebola virus disease first appearance was in two simultaneous outbreaks back in 1976. One was in Yambuku in the Democratic Republic of Congo and the other in Nzara, Sudan. The name Ebola sprout from Yambuku neighbors a river known as Ebola River. In 2014, the first case was notified in March which is the most recent and is still a current outbreak in the West of Africa. Ideally, this is the most complex and largest Ebola outbreak since the 1976 first appearance. The numbers of deaths are the highest (WHO.Int). The spread began in Guinea before spreading to the bordering nations including Liberia and Sierra Leone, then to Nigeria through one traveller on air, and to Senegal through on traveller on land. Ebola hemorrhagic fever also the Ebola virus disease or simply Ebola is a disease of primates including humans whose cause is Ebola viruses. Fever, headaches, muscle pain and sore throats are the initial signs and symptoms that develop between two days and three weeks upon contracting the virus. Decreased function of the kidney and liver then follow in addition to rash, diarrhea and vomiting. At this time, it is likely to observe both external and internal bleeding. The risk of death in relation to Ebola is significantly high. Killings between 25% and 90% are recorded of those infected which extends......

...1. What is Ebola? * Ebola is a disease of humans and other animals caused by Ebola viruses. It is called Ebola Virus Disease/EVD or Ebola Hemorrhagic fever/EHF or simply Ebola. 2. Where does the 2014 Ebola outbreak take place? * “The Ebola outbreak in West Africa is the world’s deadliest to date” says a BBC News. EVD outbreaks occur intermittently in Tropical regions of sub-Saharan Africa. The largest out break to date is the 2014 ongoing epidemic in West Africa. The outbreak began in Guinea in February and has since spread to Liberia, Sierra Leone, and Liberia. 3.  How many Ebola patients and Ebola deaths have been reported across the countries inside and outside of Africa since the 2014 Ebola outbreak? * The scale of Ebola outbreak appears to be “vastly underestimated” says the UN’s health agency. As of January 2015, this outbreak has 21,724 reported cases resulting in 8641 deaths. 4. How can the cultural practices in the West African countries spread Ebola? * Cultural practices of burial ceremonies where mourners have direct contact with the body of the deceased person do increase the threat of spreading Ebola if the deceased was infected. Other cultural practices that give rise to human to human contact, through broken skin or mucous membrane, through sharing bedding and clothing. 5. How long does a patient start showing a sign of the disease after becoming infected, describe early and final signs and symptoms? * Signs and......

Ebola Viral Disease: What Is to Be Done?

...Ebola viral disease: What is to be Done? On March 21, 2014, there was a report of a disease that was ripping through African countries. It was soon discovered that the disease was the Ebola viral disease also known as EVD. In a matter of a few short months, the Ebola virus was reported in three of Guinea’s Conakry city districts named Gueckedou, Macenta, and Kissidougou, in Liberia’s Foya district, and in Sierra Leone (Dixon, Meredith G., and Ilana J. Schafer). On October 23, 2014, there was the first recorded Ebola case in the United States. There would be three more confirmed cases before the news would declare that the United States was Ebola-free. Those that had been infected with the virus had picked them up while in Guinea and had been transported to the U.S. for treatment. There was a scare when two health care personnel tested positive with the virus while caring for others. However, due to Emory Hospital’s fantastic protocols, the virus was contained and eventually cleared from the United States (Centers for Disease Control and Prevention). Nonetheless, the Ebola viral disease is a deadly virus most commonly found in African countries in which outbreaks have occurred throughout history; but through careful procedures, and a change in current ideals, it can be contained and even prevented on a broader scale. The first main concept is the Ebola is a deadly disease that has affected hundreds around the world and currently does not have a cure. According......

Ebola

... Ebola Ebola first appeared in 1976 in 2 separate incidents which occurred at the same time. The first one in Nzara, Sudan the other in Yambuka Democratic Republic of Congo in a village near the Ebola river, from which the disease gets its name. The reason why Ebola is spreading so frequently now is because the latest case have started in Guinea und has spread into Liberia and Sierra Leone, It is stilled being carried by persons from one to the other so it has not changed. The Human is being infected by coming into contact with an animal that has the disease which then infects that person who then in turns infects other people he comes into contact with. The ways that an infected person infects another person is from direct contact through broken skin or mucous membrane with the blood or other bodily fluids or secretions of the infected person. The incubation period range from 2 to 21 days. I now from personal experience that the Military has a 21 day incubation period for all those that come back from the West Africa Region, but it is not on the same post where you are stationed but on one of the 6 posts that are specially set up for this, this areas are like you normal place of duty or home, you are there just to be checked if you have the disease as you go about your daily routine. People that are exposed to Ebola are encouraged to seek out medical attention right away so that they can get proper medical attention and if they have the disease they can be......

...International Effort to Combat Ebola By : Karinna – FE – Management – 2014 karinnali@yahoo.com / 081282689585 The disease that sent the world into frenzy used to be HIV AIDS, now, we have a new source of people anxiety, Ebola. There’s practically no one in this whole world that hasn’t heard about Ebola. The first Ebola case happened in 1976, simultaneously in 2 places, one in a village near the Ebola River in the Democratic Republic of Congo, and the other in a remote area of Sudan. Since then, Ebola has not been noticed by the international world until the current outbreak happened in March 2014 in West Africa Now, the number of death caused by ebola has reach over 4.000 and still counting. The countries with the highest death number caused by ebola are Guinea, Liberia and Sierra Leone. The disease, however, has now spread to other countries out of the Africa continent. United States of America got it’s first ebola case earlier this month. Thomas Eric Duncan travelled from Liberia to USA on September 20 and died on October 8, just a week after he was diagnosed with ebola. The extremly high death rate, up to 90%, has made many countries take precaution to prevent eloba to spread or infect their country. One of US airport, JFK, located in New York, has started to do inspection towards passengers and crew arriving from the three countries with most patients suffering from ebola. JFK is now doing health screening and ask the passengers series of questions about wheter they......

Ebola

...while avoiding measures that will create unnecessary interference with international travel or trade. Discuss this view. (15 marks) Ebola was first detected in 1976 in Sudan and Zaire (named after the Ebola River in Zaire). The first outbreak of Ebola – Sudan – infected over 284 people, having a mortality rate of 53%. A few months later, the second Ebola virus emerged from Yambuku in Zaire – the virus being called Zaire – this virus had the highest mortality rate of any of the Ebola viruses, infected 318 people. There are 3 more strains of Ebola, including the strain that is now being spread. This strain being spread now is Zaire and it is killing several people. The Ebola outbreak that broke out in West Africa is spreading faster than efforts to control it. On the 1st of August the virus has claimed to have lost 728 lives in Guinea, Liberia and Sierra Leone and statistics at this time has claimed that Ebola kills up to 90% of those infected. This virus is spread by contact with infected blood, bodily fluids, organs – or contaminated environments. Patients will have a much stronger change of survival if they receive early treatment. Initial flu like symptoms can lead to external haemorrhaging from the eyes and gums, and internal bleeding that can lead to organ failure. Currently there is no vaccine to prevent, or a treatment to cure Ebola. However it has been rumoured that we are on track to finding them. There will be trial dates set near the end of 2014 and into the......

Ebola Virus Disease Research Proposal

...Research Proposal on Ebola Virus Disease Arvaya Y. Corbins Bryant & Stratton College Research and Writing III 11/17/2014 Abstract America may not be totally prepared for what the Center for Disease Control (CDC) is currently encountering. The author examines the pandemic of diseases such as Ebola, Enterovirus, and MRSA suggesting possible ways of containment to prevent further spreading in hospitals, as well as proper diagnosis, and handling. This information was obtained through interviews with the Infection Prevention Director of Columbia St. Mary’s via Fox 6 News. Information was also obtained, evaluated, and studied from media outlets such as the Journal Sentinel, research website, Center for Disease Control and Prevention and an Ebola symposium. Lastly, the author expresses the importance of clear and concise communication between all Administration and Staff at Columbia St. Mary’s. This communication stems anywhere from clear and plain signage on doors, and entry ways of Emergency Departments, Urgent Care facilities, and Physicians’ offices. This signage communication will help an individual detect any flu like symptoms associated with the Ebola virus disease (EVD), so the proper steps can be taken immediately to isolate the disease itself. Introduction This research proposal is intended to make clear to the reader the signs, symptoms, and severity of the Ebola Virus Disease (EVD). In addition to this,......

...Ebola Kelly Minefield SCI/163 December 7, 2015 Bryn Van Patten Ebola The Ebola epidemic is the largest in history affecting multiple countries in West Africa. Two imported cases including one death and two locally acquired cases in healthcare workers have been reported in the United States. The risk of an Ebola outbreak affecting a large number of people in the U.S is very low. It is important to be educated about Ebola and other epidemics so that we can take every step to lessen the chances of an outbreak. Infectious Agents Ebola is an elongated filamentous virus, which can vary between 800 - 1000 nm in length, and can reach up to 14000 nm long ("Pathogen Safety Data Sheet - Infectious Substances", 2014).. The pleomorphic viral fragment may take on several distinct shapes, and are contained within a lipid membrane. Each virion contains a single-strand of non-segmented, negative-sense viral genomic RNA ("Pathogen Safety Data Sheet - Infectious Substances", 2014).. Ebola virions enter host cells through endocytosis and replication occurs in the cytoplasm. When infected, the virus affects the host blood coagulative and immune defence system and leads to severe immunosuppression ("Pathogen Safety Data Sheet - Infectious Substances", 2014).. Early signs that you are infected are flu-like. ......

Ebola

...March 26, 2014 the Zaire ebolavirus(EBOV) was confirmed to be the cause of the outbreak in West Africa. Up until 2014 this species had only been located in Gaban, Republic of the Congo, Central Africa, and Democratic Republic of the Congo. EBOV is considered the most deadly of the five known species of Ebola, holding true with approximately 11,000 deaths of approximately 28,000 reported cases from the start of the outbreak in March of 2014 to the present. Unfortunately there is no magic pill or cure that will destroy the Ebola virus, however with rapidly advancing technology a vaccine may be available within the year. The Ebola virus “was first identified in 1976 by Professor Peter Piot.” (Boulton, 2014, p. 988) Sudan cotton workers contracted the Ebola virus presumably from bats and when treated at the local hospital infecting many health care workers and then spreading the disease to nearby villages. This species was labeled the Sudan ebolavirus (SUDV). During the same year a few months later, in Zaire, a teacher was infected by eating bush meat, once treated at a neighboring hospital the disease spread due to re-using of contaminated needles. This species was labeled Zaire ebolavirus (EBOV). In 1989 another species was discovered, Reston ebolavirus (RESTV). Monkeys imported from the Philippines’ arrived in Virginia infected with the virus. Yet another species emerged in 1994. During a necropsy, an anthropologist was infected with Tai Forest ebolavirus (TAFV). The last......
