This paper develops a response and resource management plan for the Ebola virus, drawing on the 2014 West African epidemic. It provides foundational information about the virus, including its symptoms, diagnosis, transmission, and treatment options. The paper then outlines an incident command structure, communication strategy, and resource requirements for managing an outbreak. Additional sections address social and mental health programs for affected individuals and families, protocols for safe dead-body management, and precautionary measures for healthcare providers. Together, these components form a practical framework for public health authorities responding to an Ebola outbreak.
The Ebola epidemic, which began in 2014, is the largest epidemic witnessed in recorded history. In its initial stages, the Ebola virus affected a large number of people in West Africa, but it continued to spread and now poses a significant threat to nations across the world (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014). This paper develops a response and resource management plan that highlights the basic facts regarding the virus and the healthcare implications associated with it. In addition, it addresses the command and communication structure, resource requirements, social and mental health programs, dead-body management, and precautionary measures relevant to managing the epidemic.
Ebola, previously referred to as Ebola hemorrhagic fever, is a rare and dangerous disease caused by infection with one of the species of the Ebola virus. The virus has the tendency to cause disease in both humans and non-human primates, such as gorillas, monkeys, and chimpanzees. In 2014, the Ebola virus struck a number of African countries. The virus was first discovered in 1976 near the Ebola River, located in the Democratic Republic of the Congo. Following that discovery, the African region witnessed various intermittent outbreaks of the virus (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
Authorities have been unable to identify the natural reservoir host of the Ebola virus with certainty. Researchers have, on the basis of evidence and study of similar diseases, indicated that it is an animal-borne disease and that bats may serve as the reservoir. This is supported by the fact that four out of five known types of the virus occurred in an animal host native to Africa. Because the natural reservoir has not been conclusively identified, the mechanism by which the disease first appears in humans during an initial outbreak remains unclear. Researchers have suggested that humans may become infected through contact with an infected animal, such as a non-human primate or a fruit bat (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
The Ebola virus does not become contagious until symptoms begin to appear in the infected person. The most common signs and symptoms include fever, fatigue, severe headache, muscle pain, weakness, vomiting, diarrhea, abdominal pain, and unexplained hemorrhage (bleeding or bruising). Symptoms may appear anywhere from 2 to 21 days after a person is exposed to the virus, with an average onset of 8 to 10 days (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
The two main determinants of the speed and success of recovery from Ebola are the immune system of the affected individual and the quality of clinical care provided. People who recover from the virus develop antibodies that may last ten years or more. It has not yet been determined whether survivors are immune to the virus for life, or whether they can become infected with other Ebola species. Some survivors have also developed complications such as muscle and joint pain and vision problems (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
It is very difficult for medical officials to diagnose Ebola in an individual who has been infected for only a few days. This is because the early-stage symptoms of Ebola, including fever, are not specific to the virus and are commonly associated with other diseases such as malaria and typhoid. However, if an individual presents with fever and healthcare officials have reason to believe the person may have Ebola, the individual should be isolated immediately and public health professionals notified (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
Healthcare professionals can collect and test blood samples to confirm the presence of the virus. Ebola can only be detected in the blood after the appearance of symptoms beyond fever, which accompany an increase in viral circulation throughout the body. This detectable level may take approximately three days to develop. The laboratory tests used to diagnose Ebola are organized by stage of disease as follows (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014):
Early stages of disease: Antigen-capture enzyme-linked immunosorbent assay (ELISA) testing; IgM ELISA; polymerase chain reaction (PCR); virus isolation.
Later in the course of disease or after recovery: IgM and IgG antibodies.
In deceased individuals, for investigative purposes: Immunohistochemistry testing; PCR; virus isolation.
Once a person is infected with the Ebola virus, he or she can transmit the virus to others in a variety of ways. Ebola spreads when an individual comes into direct contact — through broken skin or unprotected mucous membranes in the eyes, nose, or mouth — with the blood or body fluids (including saliva, feces, sweat, vomit, urine, breast milk, and semen) of an infected person; objects such as needles and syringes contaminated with the virus; or infected fruit bats or primates, including apes and monkeys (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
It should be noted that Ebola does not generally spread through air, water, or food. In Africa, one contributing factor to transmission has been the handling of "bush meat" — wild animals hunted for food. Contact with bats infected with Ebola also spreads the disease. There is no evidence that mosquitoes or other insects serve as a source of Ebola transmission. Researchers have also noted that only a limited number of mammal species — including bats, monkeys, apes, and humans — can become infected with the virus (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
Once infected individuals recover from the virus, they no longer pose a transmission risk to the community. Although the virus has been detected in the semen of male survivors, it has not been conclusively determined whether sexual transmission is possible. Healthcare professionals therefore advise male survivors to refrain from sex for three months after recovery as a precautionary measure, or to use condoms if abstinence is not possible (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
No FDA-approved vaccine or specific antiviral treatment is currently available for Ebola. Healthcare professionals treat symptoms and complications as they appear. Basic interventions that, when applied early, significantly improve survival chances include: provision of intravenous fluids and electrolyte balance; effective maintenance of blood pressure and oxygen levels; and appropriate treatment of any secondary infections occurring during the course of illness. Experimental vaccines and therapeutic drugs are under development but have not yet been fully tested for safety and effectiveness (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
The spread of Ebola has raised significant public health concerns. It is recommended that informative programs be conducted to educate the public about careful hygiene practices — for example, washing hands with soap or alcohol-based sanitizers after contact with blood or body fluids, avoiding objects that may have been contaminated, refraining from attending funerals of Ebola victims, and avoiding contact with bats, non-human primates, their body fluids, and raw meat. Travel to regions in Africa with active Ebola outbreaks should also be restricted. Upon returning from affected areas, travelers should monitor their health for 21 days and contact healthcare officials immediately if any symptoms of Ebola appear (Staff Members of the National Center for Emerging and Zoonotic Infectious Diseases, Division of High-Consequence Pathogens and Pathology, 2014).
