History Of The Ebola Virus

Ebola, a virus which acquires its name from the Ebola River (located in Zaire, Africa), first emerged in September 1976, when it erupted simultaneously in 55 villages near the headwaters of the river. It seemed to come out of nowhere, and resulted in the deaths of nine out of every ten victims. Although it originated over 20 years

Ebola was named for a small river near Maridi, Sudan. Since Ebola first appeared in 1967 there have been over 100 cases of Ebola with more than 50% of the patients dying within days of their acute symptoms. Ebola is classified as a biosafety level four agent because of its extreme pathogenicity and the lack of a vaccine or antiviral drug. Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), has caused disease in nonhuman primates, but not in humans. Ebola has spread between countries starting in Guinea then spreading across land borders to Sierra Leone and Liberia, Nigeria, USA, Senegal and Mali. Ebola has been presented for more than 35 years; however, the largest outbreak began in West Africa in March 2014. Ebola was previously reported in: Nigeria, Senegal, Spain, United States, Mali, and United Kingdom. However, there are no current cases of Ebola in these countries. There were four people who were diagnosed with Ebola in the United States. The two brought ebola into the country while the other two contracted the disease after caring for an Ebola patient in the United States. One man however died from the disease and the other three recovered and are now free of Ebola. Most of these cases were due to people traveling from a country where ebola was present. This outbreak cause severe and

Historically Ebola has had a serious impact on human health and hygiene and still does due to the fact of no vaccine or treatment being discovered, but thanks to improvements in scientific and medical knowledge the virus itself is now controllable.

The filovirus Ebola consists of 4 families: Marburg, Ebola Zaire, Ebola Sudan, and Ebola Reston. It is a rather simple virus in structure; each contain a single strand RNA strand and 7 different proteins, 3 which are only slightly understood and 4 that are completely unknown. The virus harms the immune system like the HIV virus, but Ebola causes an explosive attack. The virus is associated with the measles and mumps family, pneumonia viruses, parainfluenza viruses which include colds, and respiratory system related viruses. Unlike common viruses which are ball-shaped, Ebola’s shape represents that similar to a shepherd’s crook, a long snake-like thread that looks like a worm. Because the Ebola virus has a distinct structure, it has been classified as a “thread virus” in its own family of viruses, the filoviruses.

Ebola was first discovered in 1976 near the Ebola River which is now the Democratic Republic of the Congo. There are five identified ebola virus species: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus); and the Bundibugyo virus (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), causes disease in nonhuman primates. There have been ebola outbreaks in Africa starting in 1976 and lasting until 2016. These outbreaks have occurred as a result of human to human contact with bodily fluids which happens mostly during funerals of the deceased and population migration between countries. Patterns between outbreaks could potentially

Ebola was first recognized in 1976 as the cause of outbreaks of disease in the Democratic Republic of the Congo (then known as Zaire) and in Sudan. About three hundred people in each of the two nations were infected with the virus, resulting in a mortality rate of 88% in Zaire, and 53% in Sudan (Bulletin of the WHO 1978). The disease as it was discovered spread through direct contact of unmans to humans, and then thought, from non-human primates to humans. The epidemic was a result of unsafe and unsanitary hospital practices, and non-sterilized medical equipment. The disease was then contained, however sporadic outbreaks of the Zaire and Sudan Ebola subtypes have risen in the Democratic Republic of the Congo, Gabon, Uganda, and Sudan; one of the latest outbreaks was in the Democratic Republic of the Congo in September of 2007.

Ebola was and still is a greatly talked about problem. Most people know that it is very contagious. The Ebola virus was first discovered in 1976 near the Ebola river in Congo.The greatest outbreak of Ebola started in Guinea in December 2013.Ebola is a virus with several strains and it can cause the disease Ebola hemorrhagic fever. People that are infected with the Ebola virus get their immune system destroyed and eventually start bleeding internally and externally .Depending on the outbreak from 50 - 90% of the infected die from (EBV)

At the beginning of the article, the map demonstrates through shading, that the disease stems from Nigeria, Senegal, Liberia, Sierra Leone, and Guinea. West Africa has a current Ebola outbreak in 2014. Obviously America does not want this disease present in America. The CDC (Center of Disease Control) is helping sort out this situation. The main goal of the CDC, as the text implies, is to help countries all over the world with multiple diseases to prevent the certain disease from spreading. Through the beginning of this program multiple countries have been saved, killing off this disease at its core. Although it is hard for the CDC to stop the disease in this specific situation. According to the article, many Ebola cases could have been prevented through less human involvement with animals. Animals have been spreading Ebola to people through physical encounters with them. Human encounters with animals have spread Ebola through open wounds, or touching slobber. Once interactions with an unsanitary animal occurs, people might start showing Ebola

The first cases of the 2014 epidemic were reported in Gueckedou Province, Guinea in March of 2014. This epidemic was the most geographically extensive outbreak within a single country. The first recorded outbreak occurred in simultaneous outbreaks in Democratic Republic of Congo (then Zaire) and Sudan in 1976, killing 280 out of 318 cases. (MSF UK, 2016) Fruit bats are considered to be the host of the Ebola virus. (MSF UK, 2016) There are five different strains: Bundibugyo, Ivory Coast, Reston, Sudan and Zaire, named after their places of origin. These, except for the Reston strain, have caused disease in humans.

Ebola has been located in many different African countries. Since 1976 there have been around 21 outbreaks of Ebola virus reported. However, in the 2014 outbreak, there was known to be more cases and more deaths of Ebola than all of the historical outbreaks combined together five times more. Your chances of getting Ebola are very slim. However, if you are or if you have been in a place where there has been a recent outbreak of Ebola disease your chances are at a higher risk. Scientist believe that the first person that received Ebola was a two-year-old in southern Guinea. Since 1976 to 2016 there have been 28,637 reported cases of Ebola and, they figure up to 11,315 deaths. The cause of the Ebola virus results in damaged vascular cells that are formed from the blood vessels, damage to the liver, large amounts of viruses in the blood etc. Ebola causes uncontrollable bleeding and, that eventually leads to fluid and blood loss that can cause hypotensive shock which causes death in most of the Ebola- infected victims. The virus destroys and damages the microvascular endothelial cells and this results in external and internal bleeding from the mucosal surfaces. For example, the nasal passage, gums, mouth and even

Ebola is a virus in the family Filoviridae and the genus Ebolavirus. Five virus species have been identified, four of which are known to cause disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus). The fifth

Discovered in 1976 near the Ebola River, Ebola’s first two outbreaks in Sudan and Zaire killed the majority, over half, of the people infected with the disease. Although the natural host reservoir of Ebola has yet to be found, the virus is believed to be animal-borne. A person gets Ebola from a wild animal and then is spread throughout the human population through person-to-person transmission. Healthcare workers providing aide for Ebola victims know that they have a high possibility of contracting the disease because they are exposed to infected blood and body fluids. It could take from two to twenty-one days for the Ebola Virus to show symptoms in humans, and

This viral disease is very rare which causes severe bleeding and 90 percent in deaths of those who are infected. Ebola showed up without warning in the late 2000 in the northern district of Gulu in Uganda, Africa. Health care workers separated patients from others so they wouldn’t spread and get worse. There are 40 people that died in the first wave of the epidemic. The virus killed 224 people then out of nowhere it stopped and seems to have gone back into the jungle, this was in February 2001. There is a lot we still don’t know about the Ebola virus but the scientists began to piece of the things they don’t know together. The virus was discovered in the Democratic Republican of Congo in 1976. There are four different types of Ebola viruses. They are all named from where they are discovered at: Ebola – Zaire, Ebola – Sudan, Ebola – Ivory Coast, and Ebola – Reston. In 1989, the United States the Ebola – Reston virus was found in Reston, Virginia. There were sick monkeys imported from Philipines to a research lab. Some lab workers showed signs of the virus in the blood but didn’t become ill. Still don’t know where the virus is coming frombut think it resides in rain forests of Africa and Asia. The Ebola virus might as well be animal borne passed to primates like monkeys and apes and humans by another

The ebola virus disease is a deathly illness first discovered in the late twentieth century. This disease is viral, spreading from human to human through any bodily fluid contact. Due to this process infection, it is easy enough to become unprotected and cause a mass-distribution of the disease among the human populace. Regretfully, this disease had gone undetected within West Africa until March of 2014, when it had branched off from just the one country Guinea to four of its surrounding countries. This probes as one of the world’s newest health issues since there is no vaccine to prevent this disease from sweeping across the rest of nation and infecting us all.

The first outbreaks of Ebola occurred in Africa between 1st September and 24th October 1976, there were 318 cases of the disease in northern Zaire. The outbreaks were centred in the Bumba Zone of the equator and most of these cases were recorded within a radius of 70km from Yambuku .There were a total of 280 deaths and only 38 serologically confirmed survivors.
