Case Study: Ebola virus How to create a case study The case studies are meant to be an enjoyable, interesting, and informative assignment. This is your chance to show that you understand the key teaching points about a microbe and to communicate these points to in a written format. Have at least 3-4 key referenced points in each of the five areas. The chart below suggests the type of information requested for the pathogen. Outlines can be in whatever form you prefer (bullets/charts/outlines/diagrams or a mix).

Be sure to include two discussion questions (and provide complete answers) that you can incorporate into your case study (place them at the end of your write-up). These questions should help connect your case to other material in the course. For example, what other microbes have an A-B toxin? What other viruses are transmitted by fecal-oral spread? Pertinent references can be listed at the bottom of your outline in a small font.

Use Council of Science Editors (CSE) Style format for all references. Your textbook may be listed as “Microbiology: A Human Perspective Eugene W. Nester et.al. McGraw-Hill Publisher 7th edition/ 2012â€. Typical Case What does a typical case look like?

Use the standard format for a patient presentation with chief complaint (CC), history of present illness (HPI), key physical exam details (PE), lab findings, signature signs, and any other important findings. Description of the infectious agent If it is a bacterium, how is it classified? If it is a virus, what kind of nucleic acid does it have? Does it target specific cellular types (tropism)? Does it form a spore?

Is it aerobic? Is it intracellular? Can it only be grown in a specific type of media? How is it distinguished from other members of the species? Does the pathogen have a significant history with humans or animals?

Epidemiology What do you feel are the most important points about the epidemiology of the disease? Incidence? Portal of entry? Source? Is it a normal microbiota component in the human body?

Does it only occur in certain populations or certain geographical areas? Is there a vector involved? What and who is the vector? Is it zoonotic? Does it appear seasonally?

Are there currently any outbreaks of this pathogen? What is its ecological niche? Is there a reservoir? Are there currently any outbreaks or epidemics of disease from this pathogen? Pathogenesis What is the range of diseases caused by the agent?

What organs are affected? What symptoms might the patient have? What is the disease course? Will the patient recover? Are there any long-term sequelae of infection?

Latency? Prophylaxis/Treatment Is there an antitoxin? Specific antibiotics or a class of antibiotics that are used? Is there a vaccine available? Is treatment curative?

Does infection make you immune? Is this immunity life-long? Is there drug resistance? Are there novel treatments? Discussion Questions With Responses Two (2) discussion questions with responses and scientific literature references are required to complete the Case Study; These questions should help connect your case to other material in the course.

For example, what other microbes have an A-B toxin? What other viruses are transmitted by fecal-oral spread? Is this pathogen a candidate for use as a biological weapon? Addenda For the Case Study, you are asked to provide at least the information requested in the boxes. The boxed questions are suggestions for the minimum amount of information within each category.

The more detailed the information, the better the study. You may consult your textbook, CDC, Google Scholar, NCBI, WebMD, etc. to find the information. For example, if you perform a Google search using the name of the pathogen and the word ‘vaccine’, you will find information on current vaccines (if any), those in clinical trials, vaccines used only in animals, etc. Be sure to provide two (2) discussion questions (as well as provide answers) with your case study. Your library privileges from UNE give you access to all of the scientific literature so you are able to find references, abstracts, and complete articles in most cases.

Your library privileges from UNE also give you access to the medical textbooks. Do this: Go to the UNE library page here: Click on the “Databases by Title†under UNE Online Resources (the page will be here: Scroll down to the Database “AccessMedicine†and click on it. You will see a log-in page and you can use your UNE e-mail log-in information. You should be seeing the AccessMedicine Search bar in the middle of the page. Type in your Case Study pathogen and get started.

Finally, use Google Scholar. Make a noun string of your pathogen’s Latin name and a qualifying term like “vaccines†or “virulence factorsâ€. Be sure to unclick the “patents†box before you search. The site is: I enjoy reading a narrative, but you may use bullet points for each section (the choice is yours). Council of Science Editors (CSE) Style format is fine for all references.

Be sure to consider the directions carefully and include all the requested information (especially the two discussion questions with responses and scientific literature references). What information belongs in my case study? Have at least 3-4 key referenced points in each of the five areas shown in the Case Study Information Chart (see below). The left-hand heading in the chart suggests the type of information requested for the pathogen. Outlines can be in whatever form you prefer (bullets/charts/outlines/diagrams or a mix).

Be sure to include two discussion questions (and provide complete answers) that you can incorporate into your case study (place them at the end of your write-up). These questions should help connect your case to other material in the course. For example, what other microbes have an A-B toxin? What other viruses are transmitted by fecal-oral spread? How much information should I provide for my case study?

For the Case Study, you are asked to provide at least the information requested in the chart below. The boxed questions are suggestions for the minimum amount of information within each category. The more detailed the information, the better the study. You may consult your textbook, CDC, WHO, Access Medicine, Google Scholar, NCBI, WebMD, etc. to find the information.

So: • Read the rubric carefully, provide all information, discussion questions/responses, and references in APA format. Remember that the Case Study is a teaching tool and you are, essentially, teaching me about the pathogen you selected.

Paper for above instructions

Case Study: Ebola Virus

Typical Case Presentation

- Chief Complaint (CC): High fever, severe headache, muscle pain, and unexplained bleeding.
- History of Present Illness (HPI): A 45-year-old male returns from a business trip in West Africa, presenting with symptoms that began four days after his return. Initial symptoms included fever (38.5 °C), fatigue, and gastrointestinal disturbance, followed by a rash and bleeding from mucosal surfaces.
- Key Physical Exam Details (PE):
- Vital signs: Tachycardia (heart rate of 120 bpm), hypotension (blood pressure of 90/60 mmHg), and elevated temperature.
- Increased bleeding tendencies (gum and gastrointestinal bleeding).
- Acute renal failure evident with oliguria.
- Lab Findings: Positive result for Ebola virus via Polymerase Chain Reaction (PCR) assay and key laboratory findings include thrombocytopenia, elevated liver enzymes, and leukopenia.
- Signature Signs:
- Hemorrhagic manifestations (e.g., conjunctival hemorrhage).
- Rash (maculopapular).
- Multiple organ involvement as evidenced by renal compromise.

Description of the Infectious Agent

- Classification: Ebola virus is classified as a member of the Filoviridae family. It is a non-segmented, negative-strand RNA virus.
- Nucleic Acid Structure: The virus contains a single-stranded RNA genome encapsulated in a nucleoprotein complex.
- Target Cellular Types: Primarily targets endothelial cells, macrophages, and hepatocytes, leading to cell death and promoting a dysregulated inflammatory response.
- Characteristics:
- Obligate intracellular pathogen.
- Cannot be cultured in standard growth media; requires biological assays in a biosafety-level 4 laboratory.
- Unique surface glycoproteins allow it to elude the host immune response.

Epidemiology

- Incidence: Ebola outbreaks typically have a case fatality rate between 25% to over 90%, with varying incidence depending on the virulence of the strain and local conditions.
- Portal of Entry: Infection occurs through direct contact with body fluids of infected humans or animals, including blood, saliva, and vomit.
- Transmission and Reservoir: Bats (specifically fruit bats) are considered the natural reservoir. Human-to-human transmission occurs primarily via contact with infected bodily fluids.
- Geographical Distribution: Endemic in Central and West Africa, with outbreaks recorded predominantly in Guinea, Liberia, and Sierra Leone.
- Zoonotic Aspects: Considered a zoonotic disease, with evidence of transmission from animals to humans, particularly following hunting and consumption of bushmeat.
- Current Outbreaks: At various points, outbreaks have occurred, with significant trails noted from 1976 onwards, following the discovery of the virus.

Pathogenesis

- Range of Diseases: The primary disease caused is Ebola virus disease (EVD), characterized by severe hemorrhagic fever.
- Affected Organs: Mostly affects the liver, vascular system, and immune system, leading to multi-organ dysfunction.
- Symptoms: Symptoms range from fever, fatigue, and loss of appetite to more severe conditions including hemorrhagic fever and shock.
- Disease Course: Symptoms typically appear 2-21 days after exposure; the disease can progress rapidly, and mortality is common without prompt supportive care.
- Recovery and Immunity: Survivors develop antibodies lasting for several years, but the long-term immunity's effectiveness remains uncertain (Leroy et al., 2004).

Prophylaxis/Treatment

- Available Treatments:
- Treatment involves supportive care to manage symptoms, hydration, and electrolyte balance.
- The FDA approved the use of the monoclonal antibody cocktail ZMapp as an experimental treatment.
- Vaccination: The rVSV-ZEBOV vaccine has shown efficacy in preventing EVD in clinical trials and is now deployed in outbreak responses.
- Natural Immunity: Survivors may develop antibodies, but immunity is not absolute, and reinfection can occur.
- Drug Resistance: Current therapeutic agents retain effectiveness, but concerns arise over emerging variants. Research continues on treatments like Remdesivir (Wang et al., 2020).

Discussion Questions with Responses

1. What other viruses are associated with hemorrhagic fevers, and how do they differ from Ebola?
- Other identified viruses include Marburg, Lassa, and Crimean-Congo hemorrhagic fever virus (CCHFV). While they share symptoms and can cause high mortality, they differ in their epidemiology, transmission routes, and treatment modalities. For instance, Lassa fever is endemic in West Africa, primarily transmitted via contact with rodent excreta, differing from the zoonotic transmission of Ebola (Harrison et al., 2019).
2. How does the Ebola virus compare to other viral pathogens in terms of potential use as a biological weapon?
- Ebola virus, due to its high mortality rate and ability to cause outbreaks, poses a significant threat as a potential biological weapon. Its rapid onset and severe symptoms can incite fear and societal disruption. However, stringent biosafety measures and international regulations limit its potential use in bioterrorism scenarios (Peters & LeDuc, 1999).
