The deadly ebola virus essay

These microscopic predators are viruses. In my report, I will answer many basic questions concerning one of the fastest killing viruses, the Ebola virus.

They are very similar except for small serological differences and gene sequence differences. The Reston Strain is the only one which does not affect humans. The Ebola virus was named after the Ebola river in Zaire, Africa after its first outbreak in There are many 7nm spikes which are 10nm apart from each other visible on the surface of the virus.

The average length Sorry, but full essay samples are available only for registered users Choose a Membership Plan and diameter of the virus is nm and 80nm.

The virons are highly variable in length polymorphicsome attaining lengths as long as nm. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein, a polymerase and 4 other undesignated proteins.

The genome consists of a single strand of negative RNA, which is noninfectious itself.

The order of it is as follows: The mechanism used to penetrate the membranes of cells and enter the cell is still unknown. Once the virus is inside a cell, the RNA is transcribed and replicated. The RNA is replicated in the cytoplasm and is mediated by the synthesis of an antisense positive RNA strand which serves as a template for producing additional Ebola genomes.

The virus then assembles and buds off from the host cell, while obtaining its lipoprotein coat from the outer membrane.

This destruction of the host cell occurs rapidly, while producing large numbers of viruses budding from it. The massive destruction of the liver is the trademark of Ebola.

The victim looses vast amounts of blood especially in mucosa, abdomen, pericardium and the vagina. Capillary leakage and bleeding leads to a massive loss in intravascular volume.

In fatal cases, shock and acute respiratory disorder can also be seen along with the bleeding. Numerous victims are delirious due to high fevers and many die of intractable shock. As the infection progresses, vomiting usually blacklimited kidney and liver function, chest and abdominal pain, rash and diarrhoea begin.

External bleeding from skin and injection sites and internal bleeding from organs occur due to failure of blood to clot. After the first person is infected, further spread of Ebola to other humans secondary transmission is due to direct contact with bodily fluids such as blood, secretions and excretions.

It is also spread through contact with the patients skin which carries the virus. Spread can be accomplish either by person to person transmission, needle transmission or through sexual contact. Person to person transmission occurs when people have direct contact with Ebola patients and do not have suitable protection.Eisenhut’s findings made it clear that Ebola patients must be separated from the rest of the hospital population and treated by staff wearing protective gear.

And this posed further questions. Ebola Virus The Ebola virus, named after the Ebola River in Zaire, is a highly contagious virus. History of Ebola The Ebola virus was first documented in Zimbabwe, South Africa and in Kenya in /5(10). Results from a new study may lead to approval of what could be the first drug that ameliorates potentially deadly reactions in children with severe peanut allergies.

The Deadly Ebola Virus Essay - The Ebola Virus is the common name for several strains of virus, three of which are known to cause hemorrhagic fever in humans, which is characterized by massive bleeding and destruction of internal tissues.

Ebola Zaire is the most lethal ofthe three followed by ebola Sudan and then ebola Reston. EbolaReston is the least worried about because it has not proved to be hostile to humans. The question of whether or not this virus could become airborne has struck fear in many. Sep 16,  · In this picture, you can see that the bronchial wall contains cartilage and muscle, as described above.

Also, note that different types of cells make up the lining (epithelium) of the bronchi (as well as of the trachea and bronchioles).
