For your next research paper, you can focus your topic on the Ebola virus itself or health in third world countries.
In previous outbreaks of Ebola, about 90 percent of those infected die. There is no vaccine or cure for the highly infectious disease. This most recent outbreak of the Ebola virus is believed to have originated in late or early in Guinea in West Africa. After a period when it looked like the virus was slowing down, it gained momentum again and even spread to the capital of Liberia for the first time.
Because Ebola often touches remote areas and the first cases sometimes go unrecognized, it is likely that there are deaths that go uncounted during outbreaks.
This region of West Africa, particularly the countries of Guinea, Liberia and Sierra Leone where the Ebola virus has hit hardest, has a long history of adhering to their own traditional medicine and a wariness of outside medical assistance. The fear of health officials is most likely only adding to the severity of the epidemic. Reports indicate that many of the sick are being hidden and buried without any protection to prevent further spread of the disease. And not even the doctors themselves are immune or safe.
The lead doctor fighting Ebola in Sierra Leone has died of the disease, and two other American doctors working in Liberia have tested positive for the disease.

Antiviral drugs also show promise in experimental infections [ 91 ]. The expense of preclinical and early clinical work would be justified by the potential commercial use of the drug against RSV, while the efficacy against Ebola virus would provide an alternate model to demonstrate broad-spectrum preclinical efficacy. The epidemic in Kikwit posed certain serious problems. The medical infrastructure was poor to begin with and suffered greatly from the epidemic. Because of fear and of stigmatization, new cases were cared for at home and often in secrecy.
It became urgent to rehabilitate the medical infrastructure and to convince patients to come to the hospital, where they could be isolated and their families could be observed. This contrasts with the outbreaks, which occurred in villages where leaders enforced quarantine in local houses.
This action, combined with the collapse of the medical care system, effectively ended the epidemics. The importance of the medical care facility in amplifying the spread of Ebola virus is emphasized by the fact that only the hospitals in Kikwit and Mosango, DRC, had extensive transmission: We do not know if Ebola virus transmission would have continued indefinitely, burrowed into the massof people in the city, if measures to begin hospital use had not succeeded.
In any case, the infection of health care workers [ 69 , 55 ] ended with the arrival of proper patient-isolation supplies and training in barrier-nursing techniques [ 55 , 69 , 92 ]. The coordination of medical logistics and plans for rational triage of the patients were key in the effort [ 93 , 94 ]. The lesson is obvious: The hospital is the link that must be strengthened.
This will require both money and training, but the improvements will be useful in preventing many other infections, including those with hepatitis C and human immunodeficiency viruses. How this might occur without marked economic and cultural changes is not clear; despite intensive training, health care workers in Kikwit abandoned most of the improvements in medical hygiene within 3 months of the end of the epidemic, due in part to a lack of supplies and a reversion to previous practices.
Unfortunately, the massive aid that comes with emergencies does not continue in reduced form to help prevent future emergencies. Surveillance is also a problem. The case definition that was adopted was accurate in the epidemic setting, but it would be much less so in sporadic infections or at the beginning of an epidemic [ 69 ]. The finding of copious amounts of Ebola virus antigen in skin opened the way to confirm cases by taking simple skin biopsies, which could be placed in formalin and analyzed later by immunohistochemistry [ 53 , 92 ].
This obviates the need for cold chain or special precautions while processing or shipping infectious material. One could argue that Ebola diagnostics should be placed at many sites in the potentially endemic areas, but this may be unrealistic given the small number of expected cases and the economics.
Such tests could be devised on the basis of antigen detection on paper strips [ 27 , 27a ], but the logistics of production, distribution, quality control, and shelf-life considerations are formidable. It would seem that laboratory capability for diagnosing common diseases, such as shigellosis or typhoid, would be much more practical as a first step. This would also make it easier to sort out which patients to suspect for Ebola virus infection, remembering that the initial diagnosis of the epidemic in Kikwit was bloody diarrhea until clinicians suspected otherwise weeks later [ 95 ].
Thus, the algorithm proposed by Lloyd et al. If a patient dies, as the majority of humans infected with EBO-Z do, a skin biopsy is obtained and sent for analysis. Today, the Centers for Disease Control and Prevention is the main site for analysis, but as demand builds, the technology can be transferred to regional centers.
The delay in definitive diagnosis is not the problem one might anticipate. The protocol calls for barrier nursing to begin at once, thus decreasing the chance of spread. In the Kikwit outbreak, almost 5 months passed from the beginning of the outbreak until the first samples were obtained. The ability to obtain a skin sample safely and without cold chain problems should encourage more use of this technique and may well give an earlier warning.
What information is needed to deal with Ebola virus? The major questions are tied to important issues in biology. For example, how will we be able to elucidate the natural reservoir without intensive studies of the many animals resident in the tropical forest? Do we really have a viable hypothesis as to the true reservoir?
Certainly we would put bats high on our list of suspects [ 77 ], but should we do this to the exclusion of other species [ 74 ]? Very little is known about the virology of Ebola. For example, this agent has less than a dozen genes, compared with the expansive genomes of poxviruses or herpesviruses. How does it accomplish its task of natural maintenance and also cause disease in humans? The virus appears to be relatively refractory to the antiviral effects of interferon [ 75 ], but the mechanism is unknown.
Recent studies have shown that the virus inhibits gene induction by interferons and double-stranded RNA in endothelial cells, effects that could be relevant to pathogenesis [ 96 ].
We have no structural studies of the virus that could yield information on the function of some of the unmapped genes. Additional knowledge of the three-dimensional structure of the virus and its proteins could be helpful in designing inhibitors of the fusion process [ 97 ] and of the polymerase. The clinical description of the disease is still incomplete, due in part to the lack of infrastructure during epidemics and the difficult and dangerous circumstances.
For example, does pancreatitis contribute to the demise of patients [ 36 ]? What are the variations in clinical pathology findings?
Much additional work on the virology and immunology remains. Finally, we need a pre-planned response team that is already integrated, prepared to execute selected functions, and equipped.
This team may have to wait 20 years for the next epidemic; however, its chance to respond may come much sooner. Most of the known information on filoviruses can be found in Marburg Virus Disease  , Ebola Virus Haemorrhagic Fever  , and this supplement. Marburg and Ebola Viruses  has just been published and contains, but is not limited to, particularly good summaries of recent work on the molecular biology of filoviruses.
Much of the Russian literature has never been properly surveyed and synthesized in the English language. This supplement contains reviews of Russian work on antibody therapy [ 85 ] and pathogenesis [ 99 ], and other information on pathogenesis [ ] and vaccine immunology is available [ ]. We gratefully acknowledge the work of the many field and laboratory investigators who contributed their original findings to manuscripts included in this supplement, especially to those who delayed publication so that their work might be shared in this compendium of recent research.
We also recognize the many other dedicated individuals not included in the author lines who participated in many different ways in the international responses to the Kikwit and other outbreaks, especially those whose lives were lost while assisting in the epidemic responses and caring for the sick or dead.
Finally, we thank the editorial board and the staff of the Journal of Infectious Diseases , especially Donna Mirkes and Claudia Chesley, for their patience and hard work.

Ebola Virus Visits the United States: EBO-Z, Kikwit, DRC, The description of the large African EHF outbreaks in was largely based on retrospective information, so the Kikwit epidemic provided a better opportunity for more detailed investigations while the epidemic was in progress.
Clinical disease The clinical syndrome seen among patients in Kikwit resembled that seen in [ 13 , 11 ], but bleeding was less common and other significant findings were identified, as reported by Bwaka et al. Epidemiology and surveillance The presence of the international teams allied with several organizations from the DRC during the end of the epidemic provided an opportunity for several studies to better define the transmission of Ebola virus among humans.
Ecology and natural history The epidemic also provided an opportunity to search for the elusive reservoir of Ebola virus in connection with an acute outbreak. Virology and pathogenesis Ksiazek et al.
