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.

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 control monkeys were never injected with the Ebola virus; they were placed across the room from the sick monkeys. After the control monkeys were found to be infected with Ebola it was proposed that “Ebola drifted across a room. Most likely the control monkeys inhaled it into their lungs” (Preston 93-94). Finding out that Ebola was possibly spread through the air posed as a large problem as Karl Johnson explained to Preston in an interview, “If Ebola had spread through the air, the world would be a very different place today… It would have been exceedingly difficult to contain that virus if it had had any major respiratory component” (Preston 121). The Ebola strain that Johnson encountered appeared to not be spread through the air, however there is substantial evidence that other strains are. “In 2012 Canadian researchers found that Ebola Zaire, which is involved in the current outbreak, was passed from pigs to monkeys in the air” (Cohen 1). Ebola is aggressive enough that some researchers believe it is able to enter a person’s bloodstream through a small scrape (Preston 142-143). Ebola was actually spread by medical staff in some areas such as the Yambuku Hospital where nuns used five needles a day for hundreds of their patients. This mixed blood and gave Ebola the opportunity to spread (Preston 102). It

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.

The last Ebola outbreak was merely a year ago. This tragedy is fresh; I remember watching the news in fear that Ebola would come to America…until it did. First in Texas then again when two American doctors were flown from Africa to Emory. The idea of Ebola being in my back yard was absolutely terrifying! I couldn’t stop imagining what I’m going to do when I’m a medical student and a biohazard level four patient is in the same hospital as me.

The Ebola outbreak that started in Guinea in March 2014 and that spread to Sierra Leone and Liberia later, is not the first Ebola outbreak in human history. In fact, 25 Ebola outbreaks were recorded since the virus was first discovered in 1976. But this year’s outbreak has been the severest one because of its widely geographic spread[ http://time.com/47018/ebola-breaks-out-in-west-africa/] and the lack of health infrastructure in those three countries hardest hit. Although in February, the United States and 28 other countries announced the Global Health Security Agenda, one of whose goals was to prevent and reduce the likelihood of outbreaks, the US response in the early months was not enough given the size of the disaster.[ http://ic.galegroup.com.ezaccess.libraries.psu.edu/ic/ovic/NewsDetailsPage/NewsDetailsWindow?failOverType=&query=&prodId=OVIC&windowstate=normal&contentModules=&display-query=&mode=view&displayGroupName=News&limiter=&u=psucic&currPage=&disableHighlighting=false&displayGroups=&sortBy=&source=&search_within_results=&p=OVIC&action=e&catId=&activityType=&scanId=&documentId=GALE%7CA382718305]

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

Ebola could only be transmitted through humans aswell as animals , it can be transmitted through handiling dead or ill humans aswell as chimpanzens , Ebola is transmitted through direct contact with infected body fluids or tissue.

Ebola is a nightmare virus that is known for its deadliness and with a ninety percent fatality rate it has certainly earned its reputation. The virus shows up with symptoms like influenza, aka the common cold, however the symptoms gradually or in some cases, take great turns for the worst. The virus overtakes its victims usually causing multi-organ failure resulting in death. There are rare cases where a victim can be treated, but it is only if the virus is caught early enough to treat the symptoms that may last for a few days to three weeks during which they remain contagious. Men can still transmit the virus through their semen for up to seven weeks after recovery. (Ebola 2) The World Health Organization website provides

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

First of all, Ebola is spread by “direct contact with body fluids”(Towner, 2008). Additionally, Ebola does not become infectious until the patients start seeing symptoms. In Africa, Ebola outbreaks over the past 40 years has “been brought under control with standard infectious disease measures”,

With no cure or vaccination available for the Ebola Disease Virus (EDV) it seems nearly impossible to control. It spreads very much like the common flu except that it is only passed by direct contact so there are no airborne particles yet. Furthermore, the places most at risk are hospitals, funerals, and unreported homes that contain Ebola patients, dead or alive. These places are where the Ebola virus is most easily spread from infected to non-infected. Moreover, what makes containment so difficult is that for the first three to six days people infected with Ebola show no symptoms. As a result, infected people carry the disease to new areas, and once they start showing symptoms they become a risk. Once an area has found a case of Ebola it is then isolated and all borders are closed, but people will still sneak across by land, causing further spread of the disease. However, with the help of analyst they have been able to predict the spread of Ebola over land to a degree. This is especially useful because the only way to stop Ebola at the moment, is to completely stop the spread of it over land and to have prevention packs ready. Through the use of Ebola kits, Study of regional spreading, and with

The symptoms of Ebola are a fever, headache, joint and muscle aches, vomiting, stomach pain, sore throat, diarrhea, weakness and occasionally read eyes, rashes, hiccups, and internal and external bleeding and since these symptoms are not specific to Ebola, it is difficult to clinically diagnose and can often be confused with other viruses. The ELISA testing, short for enzyme-linked immunosorbent assay, and virus isolation are a couple of examples of the types of laboratory testing that can be done to diagnose and Ebola patient. Because of how easily it can be transmitted, it is extremely difficult to treat and there is no approved, official treatment. As of now, there is not standard treatment but usually the patients are given fluids and oxygen, have their blood pressure monitored and other necessary treatment. To prevent transmission and spreading the virus, the doctors use extreme caution and wear head to toe protective gear and isolate the patient. Even though the Ebola virus is common in Africa, there has been no known outbreak in the United States. Another difficulty facing scientists and the treatment for Ebola is that the natural reservoir for the virus unknown. The natural reservoir of a virus is it’s long term host of the

In 2013, the most widespread epidemic of the Ebola virus in history broke out in West Africa. My first introduction to the virus was in the following year, when popular media and news outlets across the United States picked up the story as Ebola became less of a foreign illness and more of a true threat to the nation’s health in the event that someone happened to carry it back from Africa. For years, I have had a fascination with medicine and pathology, and when I first read the news, my thoughts went first to how the virus had managed to spread so quickly. Now, as the threat has faded from the news and the concerns of the domestic United States, my attention has turned to the nature of the spread of infectious diseases. I was

Ebola then spreads through direct contact with blood or other bodily fluids. Caregivers can contract this disease by coming in contact with blood, vomit, or other fluid. Ebola patients bleed intensely, so the chances of a caregiver contracting it is high. Also, many caregivers use rituals that require bathing the bodies, making them more vulnerable to infection. The disease is spreading from small, isolated villages to large cities, where it will be much harder to isolate patients.
