Ebola Virus Disease: Transmission, Impact, and Prevention
This paper examines the 2014 West African Ebola epidemic, described as the largest in history. It covers the origins and symptomatology of Ebola virus disease, modes of transmission, and the populations most at risk. The paper analyzes how the outbreak disrupted communities across West Africa and stresses the importance of understanding local social structures—including beliefs in sorcery and witchcraft—when designing effective public health interventions. It also addresses the need for adequate protective equipment, culturally sensitive education, increased funding for vaccines, and international precautions such as travel screenings to prevent further spread of the disease beyond West Africa.

What makes this paper effective
- Grounds its argument in specific epidemiological detail—fatality rates, incubation periods, case counts—before moving to broader social analysis, giving the paper a credible empirical foundation.
- Balances biomedical and sociocultural perspectives, acknowledging that community beliefs and infrastructure gaps are as important as clinical factors in controlling disease spread.
- Uses concrete examples (cancelled weddings and soccer matches, alternative greetings) to illustrate abstract points about community disruption, making the analysis more vivid and accessible.
Key academic technique demonstrated
The paper demonstrates effective synthesis of multiple scholarly sources across disciplines—epidemiology, transcultural nursing, and public health—to build a multidimensional argument. Rather than simply summarizing each source, the author integrates findings from Hewlett & Hewlett, the CDC, Hampton, and others into a coherent narrative about why Ebola is difficult to control and what must change.
Structure breakdown
The paper moves logically from disease definition and symptoms, through transmission mechanics and risk populations, to community-level disruption, and finally to culturally informed prevention recommendations. Each section builds on the last, escalating from clinical facts to social context to actionable policy suggestions. The conclusion briefly zooms out to the international dimension, rounding off the argument without introducing new claims.
Introduction to Ebola Virus Disease
The West African Ebola epidemic of 2014 is the largest in history and has killed many hundreds of people (Hampton, 2014, p. 1). Formerly known as Ebola hemorrhagic fever, Ebola virus disease was first identified near the Ebola River, for which the disease is named. Symptoms of the disease may not be present for up to three weeks due to the virus's incubation period. Moreover, symptoms are general and resemble those of other diseases, making definitive diagnosis difficult before laboratory testing. Symptoms include headache, fever, muscle pain, vomiting, and diarrhea.
Hampton (2014) notes that fatality rates are as high as ninety percent. Those who survive will develop antibodies that can last up to ten years (CDC, 2014). However, there are as yet no known cures or vaccines (Brumfield & Wilson, 2014). Although fewer than 2,400 cases were recorded before 2014, over 700 individuals had already died from the disease in that year alone (Brumfield, 2014).
Transmission and Risk Factors
It is uncertain exactly how the disease evolved, but there are several different strains of Ebola (Li & Chen, 2014). Direct contact with a carrier is the only known means of disease transmission. The virus can be carried in bodily fluids and can therefore be transmitted via needles as well as through direct contact with an infected person's blood or saliva. The primary high-risk zones are in West Africa, although outbreaks in the United States and Europe have been recorded due to contact with infected patients.
As Hewlett & Hewlett (2005) point out, a lack of protective gear, a lack of precautionary behaviors, belief in supernatural elements related to health and healing, and stigmatization are all factors that inhibit control of the disease and facilitate its spread. A lack of awareness of how the disease is transmitted may also lead to hazardous burial practices for those who have died from it (Turner, 2014). Although the primary populations affected are communities in West Africa, all persons who come into contact with someone who has been exposed to an infected individual are technically at risk of contracting the disease.
Community and Healthcare Impact in West Africa
Ebola heavily impacts individuals and communities with poorly developed health infrastructure in West Africa. The effects of the disease extend beyond local communities to the international healthcare community as well. Healthcare workers assisting at-risk populations in Africa may not always be taking appropriate precautions, and even when they are, exposure remains possible through daily contact with infected individuals.
The disease has had a significant and disruptive effect on communities throughout West Africa. For example, large public events ranging from weddings to soccer matches have been cancelled in an attempt to slow the spread of the disease in countries such as Uganda and Congo (Hewlett & Hewlett, 2005). Likewise, the risk of transmitting the disease via handshakes has led to the development and use of alternative greetings such as bumping elbows or snapping fingers (Hewlett & Hewlett, 2005). Although temporarily inconvenient, such measures should help prevent the unbridled spread of the disease in the communities at greatest risk.
Conclusion: Ongoing Risk and Global Implications
Outside of West Africa, the chances of contracting Ebola are low. However, Guinea, Liberia, and Sierra Leone remain high-risk areas that have yet to fully contain the disease. Travel bans help prevent the spread of the illness beyond the borders of these nations, but healthcare workers remain at risk. Continued investment in protective infrastructure, culturally informed public health education, and the development of vaccines and treatments are essential to bringing the epidemic under lasting control.
