This paper will provide a comprehensive overview of Ebola virus disease with emphasis on the clinical aspects: etiology, pathophysiology, clinical manifestations, diagnosis, and treatment.
Ebola virus disease has been identified as one of the most fatal diseases in humans. This disease was first identified in 1976, and it used to be called Ebola hemorrhagic fever since its initial outbreaks in Sudan and Democratic Republic of Congo near Ebola River, simultaneously (WHO, 2015). Since then, there have been perennial outbreaks in Central Africa, but the March 2014 outbreak in West Africa has turned out to be the most catastrophic outbreaks in which over 4,492 people have died from the disease.

Excerpt from the Book
Pathophysiology
Ebola virus disease is believed to be transmitted to humans by the fruit bats which act as natural hosts for Ebola virus. However, it is worth noting that only bat species belonging to the Pteropodidae family have been linked with Ebola transmission to humans and wildlife including porcupines, monkeys, gorillas, chimpanzees, and forest antelopes (WHO, 2015). The virus is transmitted to humans through close contact with bodily fluids including blood and secretions from infected animals. Transmission among humans occurs through direct contact with infected people, in which the virus enters the body through mucous membranes, gastrointestinal lining or broken skin (King et al., 2015). It also occurs when healthy people get into contact with contaminated materials such as clothing or surfaces. After infection, the virus undergoes rapid multiplication in which its proteins are encoded into secretory glycoprotein. This secretory glycoprotein binds g-receptors of the neutrophils, and this binding has been found to inhibit the activation of neutrophils which occurs as an immunologic response. Another form of glycoprotein binds with endothelial cells, and cause destruction to the endothelium through causing intravascular coagulation (Côté et al., 2011).
Summary of Chapters
Introduction: Provides a historical overview of the disease, tracing its identification back to 1976 and highlighting the catastrophic impact of the 2014 West African outbreak.
Etiology: Details the classification of the virus within the Filoviridae family and specifies the different species within the Ebolavirus genus, noting their varying levels of pathogenicity.
Pathophysiology: Explains the modes of transmission from animal hosts to humans and describes the cellular mechanisms through which the virus inhibits the immune response and damages endothelial cells.
Clinical Manifestations: Outlines the progression of the disease from early symptoms like fever and rash to severe late-stage complications, while detailing current diagnostic methodologies.
Treatment: Describes the current reliance on supportive therapy for patient management and mentions ongoing research into experimental agents and vaccines.
Conclusion: Summarizes the key findings regarding the origin, transmission, virulence, and diagnostic challenges of the Ebola virus disease.

Frequently Asked Questions
What is the primary focus of this document?
This paper provides a clinical overview of Ebola virus disease, covering its origins, how the virus operates, its physical symptoms, and how it is currently managed by medical professionals.
What are the central thematic areas covered?
The core themes include the etiology of the virus, its pathophysiology, the clinical manifestations observed in patients, diagnostic procedures, and existing supportive treatment protocols.
What is the primary research goal?
The objective is to synthesize information from various sources to offer a clear, structured summary of Ebola virus disease, with a particular emphasis on clinical and pathological aspects.
What methodology is used in the paper?
The work utilizes a literature review and synthesis approach, summarizing clinical data and epidemiological findings provided by reputable organizations like the WHO and medical research studies.
What does the main body of the text discuss?
It details the viral classification, the mechanisms of human infection, the progression of symptoms from early signs to severe complications, and the limitations of current medical interventions.
Which keywords best characterize the work?
Key terms include Ebola virus disease, Ebolavirus, pathophysiology, clinical manifestations, and supportive therapy.
How does the virus specifically affect the human immune system?
The virus produces a secretory glycoprotein that binds to neutrophil receptors, thereby inhibiting the immune response, while also damaging endothelial cells and causing intravascular coagulation.
Are there currently any curative agents for Ebola?
No, there is currently no specific therapeutic remedy; treatment is strictly focused on supportive care, though various antiviral agents and vaccines are currently under study.
