EBOLA FACT FILE
Ebola Virus Disease (EVD) is a severe and often fatal disease that can occur in humans and nonhuman primates (such as monkeys and gorillas). The outbreaks of EVD occur predominantly in remote villages in Central and West Africa, near tropical rainforests and where contact with animals is more likely to take place. EVD is transmitted into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals (typically nonhuman primates and fruit bats). Once a human is infected it spreads in the community through skin-to-skin contact, direct contact with the bodily fluids of an infected individual, or contact with environments that are contaminated with such fluids. The incubation

It is one of three members of the ‘Filoviridae’ family and comprises of 5 distinct species, three of which are fatal to humans. These fatal species are the ‘Zaire Ebolavirus (EBOV)’, the Reston Ebolavirus (RESTV), and the Sudan Ebolavirus (SUDV). Due to the difficulty in obtaining samples and studying the disease because of the remote areas in which it outbreaks, the cause of Ebola is not yet defined. However, it is greatly suspected that fruit bats carry and spread the virus (through their droppings) without being affected. As mentioned above, the virus is then transmitted to humans through contact with the infected bodily fluids of an infected organism or …show more content…
Diagnosing Ebola in an individual who has been infected for only a few days is difficult, as the early symptoms such as a skin rash and fevers are nonspecific to the Ebola virus and are seen often in patients with more commonly occurring diseases. This can cause the virus to develop so much that it can no longer be treated and the high death toll is a direct result of this. Death of Ebola victims usually occurs during the second week of Ebola symptoms and is mostly due to extreme blood loss.
Pathogenesis of Ebola
Treatment of Ebola
The standard treatment for Ebola is still limited to supportive therapy as no vaccines are yet available for clinical use. The supportive therapy consists of balancing the patient’s fluids and electrolytes, maintaining the patient’s oxygen status and blood pressure, and treating the patient for any complicating infections. Treatment from the day the virus is contracted is important but extremely challenging due to the fact that Ebola is very difficult to diagnose in its early stages of infection. However, if a person has the early symptoms of Ebola and there is reason to believe that Ebola should be considered it is extremely important that the patient is isolated
In 2014, Ebola hemorrhagic fever caused an outbreak in West Africa that officially ended in 2016. The Centers for Disease Control and Prevention (CDC) says, “Ebola is a rare and deadly disease caused by infection with one of the Ebola virus species” (“Ebola (Ebola Virus Disease)”). Ebola is caused when a person is in contact with an infected person’s blood or other body fluids. Prevention of contracting the disease include, not touching the dead body of an infected person, not touching body fluids of an infected person, avoiding places infected people are being treated, not touching bats or nonhuman primates
The filovirus family encompasses two genera: Ebolavirus and Marburgvirus; note that filoviruses are zoonotic, and have recently been traced to some species of African bats (CDC 2014). Currently, there are four species of ebolavirus that cause disease in humans: Ebola virus, Sudan virus, Tai Forest virus, and Bundibugyo virus (CDC 2015 B, 1). For the purposes of this scenario, Ebola virus will be the agent of focus and use. Symptoms of Ebola virus infection range from common illness characteristics, such as fever and fatigue, to the more detrimental characteristics of unexplained bleeding, vomiting, diarrhea, and body pains; symptoms can appear anywhere from two days to three weeks after exposure (CDC 2015 B, 1). Transmission of infection occurs through direct contact between an individual’s mucous membranes or broken skin and body fluids of an infected person (CDC 2015 A). Body fluids can include sweat, saliva, blood, semen, and urine, amongst several others. The US Centers for Disease Control and Prevention has stated that “Although … the viruses display some capability of infection through small-particle aerosols, airborne spread among humans has not been clearly demonstrated”
Ebola virus disease (EVD) is a rare deadly infection that is caused by one of five identified strains of the Ebola virus.
In late 2013, Ebola virus disease (EVD), a deadly and lethal disease, remerged in West Africa spreading to various countries in the region. In humans, the disease is spread through contact with infected bodily fluids leading to haemorrhagic fever (World Health Organization [WHO], 2015). Originating in 1976 in equatorial Africa, past outbreaks with a few hundred cases had been contained within rural, forested areas in Uganda and Congo (Piot, 2012). In 2014, a total of 20, 206 cases and 7,905 deaths were reported to have occurred in up to eight countries worldwide. Of all cases and deaths resulting from the disease, 99.8% occurred in three neighbouring West African countries - Liberia, Sierra Leone and Guinea (WHO, 2014). With a case fatality rate from about 50% to 90%, and the absence of preventative or curative therapies, the Ebola epidemic has led to overall global alarm and further elucidated existing global health disparities that perpetuated the epidemic with these West African countries.
While Ebola is not an airborne virus, it can be transmitted through direct contact with an infected person’s fluids, such as blood, urine, vomit, sweat, semen and sexual contact (Nevins, 2014). With these deadly symptoms and ease of transmission, the Ebola virus can quickly wipe out an entire community. Yet, scientists have found that the severity of the disease in humans varies widely, from rapid fatality to mild illness or even asymptomatic response, further complicating the ability to quickly identify infected patients and reduce the possibility of transmission (Kolata, 2014). Moreover, the virus has different strains and mutates according to the specific environmental conditions in which it exists (Peters et al., 1991).
First discovered in the 1970’s, the ebola virus was contained to West Africa (“About Ebola Virus Disease”). Villagers’ diets consisted primarily of the resources readily available. Among these resources were fruit, vegetables, and animals, namely monkeys. Monkeys carried the ebola virus, and when people ate them, without proper cleaning and cooking techniques, they became infected. Ebola, formally known as Zaire Ebola Virus, is transmitted through bodily fluids like saliva, blood, semen, breast milk, mucus, sweat, tears, feces and urine. ("Ebola in West Africa."). Since it was introduced to a third world country, where hygiene is not regarded as important as survival. Without education, protection and segregated sewage, the virus began to spread. In days people were dying after spreading the virus to those closest to them (Waterman). The bodies, though dead, were still harboring the virus and
Ebola is one of the most deadly diseases known to man. The mortality rate of Ebola ranges from 25% to 90% (World Health Organization [WHO], 2014; Centers for Disease Control and Prevention [CDC], 2010; Cowart, 2014). There is no cure for Ebola and no vaccine to prevent its spread (WHO, 2014; CDC, 2010; Cowart, 2014). The virus itself is spreads between organisms through bodily fluids, such as blood and vomit, which are shed by an infected individual (WHO, 2014; CDC, 2010). These fluids typically carry a large viral load, or number of cells that harbor the virus (WHO, 2014; CDC, 2010). The virus is spread when infectious bodily fluids come into contact with mucous membranes (WHO, 2014; CDC, 2010). As such, infection can occur when infectious fluids enter a cut, enter intravenously, or encounter mucous membranes, such as the eyes, nose, or mouth (WHO, 2014; CDC, 2010).
Ebola is the global killer and communicable disease of the world with 69 % case fatality rate, whereas only Zaire strain virus has 90% case fatality rate. It attacks Guinea, Liberia, Sierra Leone, especially the west African’s region as
Ebola is the virus Ebolavirus (EBOV), a viral genus, and the disease Ebola hemorrhagic fever (EHF), a viral hemorrhagic fever (VHF). The virus is named after the Ebola River Valley in the Democratic Republic of the Congo (formerly Zaire), which is near the site of the first recognized outbreak in 1976 at a mission hospital run by Flemish nuns. It has remained largely obscure until 1989 when several widely publicized outbreaks occurred among
The Ebola Haemorrahagic Fever, or Ebola for short, was first recognized as a virus in 1967. The first breakout that caused the Ebola virus to be recognized was in Zaire with 318 people infected and 280 killed. There are five subtypes of the Ebola virus, but only four of them affect humans. There are the Ebola-Zaire, Ebola-Sudan, Ebola-Ivory Coast and the Ebola-Bundibugyo. The fifth one, the Ebola-Reston, only affects nonhuman primates. The Ebola-Zaire was recognized on August 26, 1976 with a 44 year old schoolteacher as the first reported case. The Ebola-Sudan virus was also recognized in 1976 and was thought to be that same as Ebola-Zaire and it is thought to have broken out in a cotton factory in the Sudan. The Ebola-Ivory Coast was
Ebola is a fever-bound viral disease which belongs to the Filoviridae family and is extremely fatal. When it first appeared in 1976, it claimed 90% of its recipients. Ebola originated from Nzara, Sudan and Yambuku of the Democratic Republic of Congo. Its name originates from the Ebola River where it was first contracted in Yambuku. Since its initial outbreak and more recent understanding of the disease, medical amends have reduced the mortality rate greatly but it still spans from about 25% to 90% nonetheless. Before its outbreak in the United States in 2014, there were roughly 2300 cases with over 1500 deaths. In 2014, the US had its first outbreak of Ebola with 11 total cases documented where there were 2 deaths. Symptoms include fever,
The Ebola virus, which is native to regions of Africa, causes an illness resulting in severe bleeding, organ failure, and even death. Outbreaks in Africa and other regions occur often. The virus is transferred from person to person through contact with infected bodily fluids of sharing needles. Once contracted, a patient will experience sudden symptoms such as fever, headache, aches, chills, and weakness. As the disease progresses, the symptoms become more severe. The symptoms of later cases of Ebola include nausea, vomiting, diarrhea, red eyes, rashes, chest or stomach pain, cough, severe weight loss, and internal; bleeding. There is no medication that can effectively treat the disease. Care for Ebola patients may include
Ebola is a deadly disease that caused by infection with a strain of ebola virus. Ebola spread through contact with blood and body fluids. Ebola can not be spread through water and air. That means it spread by physical contact. It’s believed that the first human was infected animal such as a fruit but or primate (apes and Monkeys). The 2014 Ebola outbreak is the largest Ebola outbreak in history and the first Ebola outbreak in West Africa.
Ebola Virus Disease (EVD) is a rare and devastating disease that causes a public health crisis every time there is an outbreak. (JAMA) It’s most common victims are humans and primates like monkeys, chimpanzees and gorillas. EVD is caused by being infected with one of the five species of Ebola. Only four of the viruses will cause the disease to develop in people, Zaire ebolavirus, Sudan ebolavirus, Tai Forest ebolavirus, Bundibugyo virus and Reston ebolavirus. The strand of the virus that is heard about the most in the news and is responsible for the most recent out breaks in the Democratic Republic of the Congo is the Zaire species of the Ebola virus (CDC).
The Ebola Virus is an extremely deadly virus found in Africa. There have been multiple outbreaks across Africa and one in the United States. The Ebola virus basically causes uncontrollable bleeding externally and internally. Then your organs become liquefied. This usually results in death(www.encyclopedia.com). The following report contains info on the characteristics and history of the Ebola Virus.
