Ebola can infect humans by someone sneezing or coughing and then you breathing it in through either your mouth or your nose. The virus can also get in to an open wound. Once the virus is in your throat the viruses keys (on the outside of the virus) look for a match which they can attach with the locks of your throat. If the keys and locks match, they attach. When attached onto your throat, the virus is taken to the welcoming barrier which from there the virus is taken to the nucleus. Once at the nucleus the virus uses your body’ s machinery to to be able to multiply. Viruses can spread from 1 to 1 million in a short time as all they want to do is spread.
Disease is any change that disrupts the normal function of one or more body functions.

Killers use a special password called: Antibodies
B cells are a third class of important immune system cells. They do not kill the invaders, but they do tell the killers who to kill. B cells produce specific protein called Antibodies. Each B cell watches out for a particular pathogen and when that pathogen arrives, e B cell begins to produce specific antibodies. Antibodies attach themselves to the specific pathogen so that the killers can recognise that these pathogens need to be destroyed.
The first time a pathogen enters the body, It will take the immune system several days to build up its peak and the overall response is relatively weak but the second time that a pathogen enters the body, the immune system will respond quickly and vigorously. Viruses can be spread around your whole body very easily which the means that you can become infected in a day or two. We are lucky to have 100 trillion cells because that means that we could fight off these viruses but Ebola is stronger than other viruses meaning that most times we cannot fight it off. That is why many people die when they have
2.Ebola spreads due to direct contact with body fluids such as blood and saliva, and it most commonly enters the body when people take care of patients with the disease poorly. The outbreak in 2014 was much larger that the one in the 1970s because in the 1970s outbreaks, people who contracted the virus would have most likely died before they could come in contact with any
1) Ebola Virus- Belongs to the family Filoviridae. It has a single-stranded -sRNA genome, so it uses a RNA polymerase to create the +sRNA template, which acts as mRNA inside the host cell. The envelope is made up of peptidoglycan; the structure is made up of 7 structural proteins and 1 non-structural protein. This means it is an enveloped and susceptible to the outside environment. The Ebola virus replicates in Monocytes, Macrophages and Dendritic Cells. When the Ebola virus is ready to leave the host cell it buds out and takes part of the cell membrane with it. Ebola has an incubation period of 8-10 days. (CDC)
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 is described by the author in deep detail telling the progression of which it goes through. It starts with a headache and backache and ends with all of your internal organs failing “bleeding out” like Charles Monet. There are four filoviruses: Ebola virus (EBOV), Sudan virus (SUDV), Marburg virus (MARV), and Ravn virus (RAVV). They are all Level 4 biohazard, which means they are extremely dangerous to humans especially because they are so infectious, have a high death rate, and there are no medicines, treatments, or cures.
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)
The time needed for Ebola virus replication in infected body cells takes less than eight hours. Hundreds to thousands of new viral particles can be produced and released from the host cell within days or even hours before the host cell dies. This replication process is repeated several times in an Ebola patient before symptoms begin to show.
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.
Therefore we ask ourselves, why is it important to discuss the Ebola virus? The answer is simple; because we need to know how the disease infects humans, and how researchers and medical professionals can prevent the virus from entering the organism. It is important to know that humans are not the host organism, or Ebola's natural reservoir; humans simply become infected when they come in contact with the infected host, such as non-human primate, pigs, or even insects.
For humans, Ebola is a viral hemorrhagic fever caused by the ebolaviruses. The virus is from the Filoviridae family. “Ebola is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals such as chimpanzees, gorillas, fruit bats, monkeys, forest antelope, and porcupines found ill or dead or in the rainforest. Ebola then spreads through human-to-human transmission via direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people, and with surfaces and materials (e.g. bedding, clothing) contaminated with
“The disease spread like wildfire” (Osterath). As the year 2014 went along more and more people knew that Ebola was as serious of a disease as any. Ebola started in Sierra Leone a country in West Africa. The first case was recorded in March 23, 2014 “It was the largest and longest ebola outbreak in history” (Osterath). The disease itself is relatively old as it was first seen in 1976 in the country of Sudan and the Democratic Republic of Congo. Ebola comes from people eating wild animals like bats and monkeys who are the natural carrier of the disease. The disease is most commonly transmitted by blood and other bodily fluids.The Ebola outbreak in Sierra Leone was one of the worst outbreaks in history. Ebola killed thousands of people and left the country and its people in a constant state of chaos.
Ebola is so deadly, because it basically takes control over the body’s immune system (Cowart, 2014; Sullivan, Yan, and Nabel, 2003). Since Ebola targets the immune and vascular system, it pretty much targets all organs within the body (Cowart, 2014; Chan, 2014; Sullivan, Yan, and Nabel, 2003). According to Sullivan, Yan, and Nabel (2003), once the virus enters the body, it replicates at an accelerated rate overwhelming the body’s immune system. Upon infection with the virus, the virus invades the body’s monocytes and macrophages, which release cytokines that travel throughout a person’s vascular
To begin with, it is absurd how some people discriminate the people who suffer the Ebola disease. After several researches I was luckily enough to run into Kari Lyndersen’s article named “ The Ebola Explosion” in which she stated, “But the virus is not especially contagious. It's transmitted only via close contact with a patient's bodily fluids, excretions, soiled clothing or bedding.” This quote is able to explain that Ebola is not a
Ebola is one of the deadliest viruses known to mankind! Ebola was originally named Ebola hemorrhagic fever due to its hemorrhagic nature. It is a rare but deadly disease caused by infection from an Ebola virus vector. Ebola can be contracted by humans and nonhumans such as monkeys, gorillas, and chimpanzees. The Ebola virus has been detected in blood and many body fluids, including: saliva, mucus, vomit, feces, sweat, tears, breast milk, urine, semen, and vaginal fluids (Willett 16). Ebola can linger in your body for several days after recovery in organs such as the testes, eyes and spinal column fluid because it is not easily reached by the immune system. Ebola can also live on the surface of an object for several hours; it can live in
Ebola infection ailment otherwise called Ebola hemorrhagic fever (EHF) or just Ebola, is a viral hemorrhagic fever of people and different primates brought on by ebolaviruses. Signs and Symptoms ordinarily begin between two days and three weeks in the wake of getting the infection with a fever,sore throat, strong agony, and cerebral pains.
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?
