Ebola Impact on Human Health & Hygiene Essay
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.
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

In 2003 a vaccine using an adenoviral vector carrying the Ebola spike protein was tested on crab-eating macaques. The monkeys were challenged with the virus twenty-eight days later, and remained resistant.
Outbreaks of Ebola, with the exception of Reston Ebolavirus, have mainly been restricted to Africa. * The Zaire virus, formerly named Zaire Ebolavirus, has the highest case-fatality rate, up to 90% in some epidemics, with an average case fatality rate of approximately 83% over 27 years. The first outbreak took place on 26 August 1976 in Yambuku. * The Sudan Ebolavirus was the second species of Ebola emerging simultaneously with the Zaire virus. It was believed to have originated amongst cotton factory workers in Nzara, Sudan. The most recent outbreak occurred in May 2004 in Yambio County, Sudan. The average fatality rates for SEBOV were 54% in 1976, 68% in 1979, and 53% in 2000 and 2001. * The Reston Ebolavirus was discovered during an outbreak of Simian hemorrhagic fever virus (SHFV) in crab-eating macaques from Hazleton Laboratories (now Covance) in 1989. Since the initial outbreak in Reston, Virginia, it has emerged in Siena Italy, Texas, and among pigs in the Philippines. Despite its status as a Level-4 organism, it is non-pathogenic to humans although hazardous in monkeys. * The Ivory Coast Ebolavirus also referred to as Tai Ebolavirus, was first discovered among chimpanzees from the Tai
The Ebola virus was first discovered in the year 1976 in Africa. Since then, there have been
It is vital to understand deadly viruses and their history in order to prevent future outbreaks. Ebola leaves very few clues after annihilating its victims, so it is incredibly important to analyze those clues. Ebola’s close relationship to monkeys contains key knowledge that could hold the secret to its success. Paying close attention to how Ebola is spreading and mutating could lead researchers to the answer for preventing the contraction of it. Discovering where and how the virus first emerged could lead to Ebola’s end.
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
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
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.
Although Ebola caught the world’s attention during the 1995 outbreak in Zaire, the first outbreak occurred in 1976. As the chart below displays, 71% of the people infected died as a result of Ebola during this first outbreak (Bulletin of the World Health Organization, 56 (2): 247-270, 1978). With the current outbreak, this ratio has dramatically decreased as a result of scientific research leading to early detection, but the current infected population is more than 20 times the amount of any previous outbreak and this number continues to grow as no vaccine exists to prevent the disease.
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
The first two Ebola outbreaks were in 1976, in the countries of Zaire and western Sudan. These were large outbreaks, resulting in more than 550 cases and 340 deaths. In 1979, Ebola mysteriously appeared in
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
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.
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, 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
Normally infecting fruit bats, the Ebola virus found a mutation allowing it to spread to humans. This virus is an acute and often fatal illness. This virus first erupted in two outbreaks in 1976 (one occurring in Nzara and Sudan, while the other occurred in a village near the Ebola river, where the virus takes its name.) The current outbreak, starting in West Africa with the potential to spread throughout the world, is larger and more complex than previous outbreaks. This virus has caused more deaths than all other past Ebola outbreaks combined. With approximately five people infected with the virus every hour in Sierra Leone alone, how far – and how fast – will the Ebola virus go?
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.
The Ebola virus was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of the Congo (CDC, About Ebola). Ebola was also known as Ebola hemorrhagic fever which is a zoonotic disease caused by direct contact with infected or dead animals ("The Natural History of Ebola Virus in Africa."). According to the Centers For Disease Control, there are four to five types of Ebola viruses but only four are known to cause diseases in human which are: the Ebola virus; Sudan Virus; Taї virus; and Bundibugyo. The fifth is the Reston Virus which causes diseases in nonhuman but does not affect humans. The whereabouts of where the virus came from is unknown but researchers believe that the virus is animal-borne (animals that carry the virus) and that bats are the carriers based on evidence and similar viruses they have found. Four of the five virus mostly occur in an animal host native to Africa (Centers for Disease Control and Prevention (CDC)). The virus does not affect the host’s deoxyribonucleic acid (DNA)-encodes genes but the ribonucleic acid (RNA)-encodes proteins.
